Calories ... and Taubes, NuSI, Ludwig & Co.

Preface


This is going to be a bit of a ramble ... one of those "oh the odd coincidences of blogging life" type posts.  It was brought on by my post citing ItstheWooo's use of traditional ELMM methods to lose and control her weight and her irrational -- I think we're up to five posts now -- tirade in response.  I'll have more to say regarding this and specific defamatory comments published on her site, but for now, here's how it started.

When Kosloff posted the 11 "experts" post, it got rather more roundly shared about the internet than usual thanks to someone's brain fart over at Whole9.  Now Kosloff didn't see fit to actually link to the sources of his copious quotes (bad Yalie), but I recognized my wording amongst Wooo's diatribe:

“Ya know blog, I’m not sure if [the CICO advocates] are actually purposefully pretending to misunderstand the hormone hypothesis argument, or if they really are too stupid to understand it. I just can’t tell. In my view it is beyond evident physiological factors are responsible for fat mass gain; calories and the mechanisms to obtain them (sloth/gluttony) are merely reactive to the body state which is controlled by baseline physiology.  So, when [the CICO advocates] for years and years and *years* keep writing mind numbingly stupid shit like this:
‘We again are asked to ignore the obvious — that Americans are definitely eating more, on average, with no concurrent need for those calories, and likely moving a bit less as well.’
I just don’t know what to think anymore. Are they morons? Are they so, so stupid they really can’t see the inverse projection of this system, which much more intelligent people have gone to great lengths to simplify and make child-friendly illustrations for them? Are they *pretending* not to understand because they have a vested interest in eating as much neurotransmitter plastering glucose/insulin whenever they want? Are they so rigid minded and dogmatic, not unlike a cartoonish villian such as Javert, that they can’t at all waver from their convictions no matter how ridiculous those convictions reveal themselves to be?”
Without links I was left to Google to track down where I said that and it turns out it was here:  Will NuSI clear the bar?   That post was written almost a year ago, and while I don't think my words above need any context, the article was a response to yet another editorial by Gary Taubes promoting NuSI and how we will one day know the answer to obesity and the mystery that is Donald Trump's hair.  My synopsis:
We get the rehashing of how WWII stopped Bergmann and Bauer's Lipophilia Hypothesis from becoming the working hypothesis for obesity, and yet another primer on calories vs. carbohydrates. We again are asked to ignore the obvious -- that Americans are definitely eating more, on average, with no concurrent need for those calories, and likely moving a bit less as well. The obesity epidemic that supposedly was instigated by the low fat craze is blamed on the fact that much of our additional caloric load is in the form of carbohydrates. This is not supported by one of Gary Taubes' own paradoxical cultures, the Pima, who did not eat a low carb diet prior to the 1900's, let alone billions of humans all over the globe. Or .... despite the "modern paleo's" insistence, the paleolithic diet in the literature -- both cited for the basis of the diet and that used in clinical trials.
Horrible stuff I tell ya.  Can someone please explain to me why, if we are unquestionably eating more as a country, we need to look further for the cause of the rising obesity rates?  Taubes says we're eating more because we're growing fatter, but that makes no sense.  Sorry, but some en masse hormonally induced horizontal growth disorder is not possible, nor is it explained by any honest observation of all of the evidence.    Before going off on another rant against me and things I have NOT said, how about you address this concept.  Americans are eating more.  We weigh more as a result.  If you want to make it into some moral judgment, be my guest.  I am not.   How does the *fact* that we are eating more without any increase in the need for those calories (and likely less need for them) not explain the obesity epidemic??  Three, two, one ....


With that introduction ...


Gary Taubes is an intriguing man.  Sometimes I do wish I had the stalking and sleuthing abilities so many ascribe to me to figure out what makes the guy tick, but alas I do not.   Have you ever wondered how it was that Gary Taubes received a three-quarter of a million dollar advance to write Good Calories, Bad Calories ... from Knopf?  I realize Knopf is a subsidiary of a larger publishing house, but still.  Taubes' book Nobel Dreams was published in the late 1980's, and it hardly made him a household name.  Despite being in my general field of interest, I never heard of the book back when, it does not appear to have sold all that incredibly well, and it doesn't appear to have been all that well received by this reviewer in the NYT:
... Yet, disappointingly, ''Nobel Dreams'' does not appall us. Despite all the cues to shock and cynicism that Mr. Taubes has planted in his text, its effect is strangely muted. Indeed, it requires an effort even to lift an eyebrow. First, Mr. Taubes never makes of Carlo Rubbia the monster that his drama seems to require. The case against Mr. Rubbia often seems lame and petty: ''He was considered one the three toughest men to work for at CERN,'' writes Mr. Taubes, speaking of the European Center for Nuclear Research, ''and as far as I can tell, few physicists who worked for him liked him.'' ...
... More damagingly, Mr. Taubes -who studied physics at Harvard, aeronautical and astronautical engineering at Stanford and journalism at Columbia - fails to make satisfyingly clear what Carlo Rubbia and his team of physicists were up to. ...

... Foreseeing long before the end of the book how the story is going to turn out, we find it increasingly hard to pay attention. This seems a shame, because the author appears to have had a compelling story to tell. But something seems to have distracted him as well - some urge to strut instead of inform. Instead of a conduit, he acts as an obstruction. Or in the jargon of physics, he decays instead of conducting.
I'm aware of articles published in the interim, but there are no other books to be found bearing Taubes' name.  [Edit: thanks to Glenn in comments, there was another book in 1993]  And then,  some 15 years later, Gary Taubes writes two articles, the second of which seems more popularly designated as "the article", a NYT Magazine piece entitled:  What if It's All Been a Big Fat Lie?  Taubes opens with:
If the members of the American medical establishment were to have a collective find-yourself-standing-naked-in-Times-Square-type nightmare, this might be it. They spend 30 years ridiculing Robert Atkins, author of the phenomenally-best-selling ''Dr. Atkins' Diet Revolution'' and ''Dr. Atkins' New Diet Revolution,'' accusing the Manhattan doctor of quackery and fraud, only to discover that the unrepentant Atkins was right all along. Or maybe it's this: they find that their very own dietary recommendations -- eat less fat and more carbohydrates -- are the cause of the rampaging epidemic of obesity in America. Or, just possibly this: they find out both of the above are true.
I've read this piece a few times over the years.  In some ways it lacks even Taubes usual "flair" for lack of a better word.  Not only that, but to this day Atkins has never been shown to have been "right all along".   Indeed he's pretty much been shown to be wrong.   Did anyone really find that single article so compelling as to warrant a $700,000+ advance to write a science book?  Perhaps we'll get the scoop in a decade or so when he writes his memoirs ...   It's just odd ... such advances are for superstars writing sure-bet #1 best sellers.   So then I click on page 2 of Big Fat Lie, and something jumps off the page at me:
The science behind the alternative hypothesis can be called Endocrinology 101, which is how it's referred to by David Ludwig, a researcher at Harvard Medical School who runs the pediatric obesity clinic at Children's Hospital Boston, and who prescribes his own version of a carbohydrate-restricted diet to his patients. Endocrinology 101 requires an understanding of how carbohydrates affect insulin and blood sugar and in turn fat metabolism and appetite. This is basic endocrinology, Ludwig says, which is the study of hormones, and it is still considered radical because the low-fat dietary wisdom emerged in the 1960's from researchers almost exclusively concerned with the effect of fat on cholesterol and heart disease. At the time, Endocrinology 101 was still underdeveloped, and so it was ignored. Now that this science is becoming clear, it has to fight a quarter century of anti-fat prejudice.
Ludwig has made a lot of waves of late, co-authoring a NYT opinion piece Always Hungry? Here's Why,  and a corresponding editorial in JAMA Increasing Adiposity. Consequence or Cause of Overeating? with NuSI VP of Research, Mark Friedman.   The obesity clinic is now the New Balance obesity clinic ... I guess since they're a sneaker and fitness apparel company such corporate sponsorship is OK, but I wonder where the line will be drawn in this regard if this is some new trend ;-)

But anyway .... I was curious to see if Ludwig was quoted in GCBC.  Search initiated .... nothing.  Searched WWGF, ditto.   I'm not sure why I searched on Friedman's name but here's an interesting thing that turned up when I did.  From GCBC:
Drafts of this book were read in part or in whole and corrections suggested by Robert Bauchwitz, John Benditt, Kenneth Carpenter, Michael Eades, Richard Feinman, Mark Friedman, Richard Hanson, David Jacobs , Cynthia Kenyon, Ron Krauss , Mitch Lazar, Jamie Robins, Bruce Schechter, Jeremy Stone, Clifford Taubes, Nina Teicholz, and Eric Westman. I am deeply grateful to all these individuals for their time , their efforts, and their acumen . Any errors in either fact or form, however, remain mine alone.   {KL 13153}
Either that Men's Health article is even more fishy for plagerism (sic) or maybe Nina Teicholz did the writing for Taubes' book?  The mind boggles at the appropriateness of the IHC acronym once again ...

But let's get back to Ludwig.  He was implied to be on board with the Endocrinology 101 over a decade ago.  A big wig researcher at Haahvaahd.  Why wasn't he in the book?  In the intervening years Ludwig has enjoyed scientific comfort in continual NIH funding on low glycemic index diets.   Perhaps it was because he was busy researching and writing a book called Ending the Food Fight:  Guide Your Child to a Healthy Weight in a Fast Food/Fake Food World , published in 2007.   This book was loved by seemingly one and all:  Willett, Nestle, Pollan, Weil, Hyman, Agatston and Brownell.  That website (ht CharlesG) is a wealth of information.  

Ludwig has been on the insulin kick for a long while, but he has not taken anything even remotely resembling the Atkins approach.  He's America's Jenny Brand-Miller and he's about low-glycemic index, but the book is also not just about diet, but activity and forming good habits.  From the Q&A:

What is Ending the Food Fight about?
Ultimately, the solution to obesity is simple: eat less and exercise more. However, for the vast majority, and especially children, this simple solution hasn’t worked. ... [talks about other factors besides diet]
... Bookstore shelves are lined with simplistic weight-loss plans addressing just part of the problem. But even the best possible diet won’t work if people can’t (or lack the motivation to) follow it. Conversely, the best possible behavior change plan will ultimately fail if it advocates a diet that exacerbates hunger and diminishes energy level. Ending the Food Fight aims for a comprehensive solution. First, we must make peace within ourselves by learning to eat in a way that works with our basic biology. Next, parents must learn effective, age-appropriate strategies so that they and their children work together, not fight. In our present “toxic” environment, the family is the last bastion of protection for the children. Finally, having brought healing to our children within the family, we must turn our efforts outward, making changes in society that will support a healthful lifestyle for all of us. Then we can lay down our arms as the food fight ends.
Where have previous weight-loss diets gone wrong?
For much of the last half-century, the most common approach to preventing and treating obesity has been a low-fat diet. It seemed to make sense: if you don’t want fat on your body, don’t put fat into your body. The problem is that it didn’t work. Recent research from our group and others has shown that the relative amount of fat in the diet isn’t an important determinant of body weight. And low-fat diets have been notoriously unsuccessful. In the past five years, the pendulum has swung very far in the other direction, with the enormous popularity of the Atkins’-type, very low carbohydrate diets. These diets do produce significant weight loss for a few months. However, studies show that by one year, much of the weight is regained. How long can one go on bacon double-cheeseburgers, hold the bun? The basic problem with many diets is that they lack an accurate understanding of how food affects our hormones and metabolism, and ultimately our well-being. Diets that restrict an entire class of nutrients, fat or carbohydrate, produce biological and psychological deprivation that we can ignore for only a short time. Instead, we advocate a low-glycemic diet designed to stabilize blood sugar and insulin after the meal, promoting long-term satiety and supporting metabolism. This approach, focused on nutrient quality rather than quantity, offers the widest possible range of food choices, providing a sense of abundance instead of deprivation. Dozens of scientific studies suggest that this approach may be remarkably effective, not just for weight loss, but also to prevent heart disease and diabetes.
Now, perhaps it's because Taubes didn't include Ludwig in GCBC, but man did Teicholz ignore him when she wrote:
Despite the no-love-lost nature of the relationship between Taubes and mainstream nutrition experts, much of what he wrote seemed so eminently believable that it was almost immediately adopted ...  Researchers around the country who had read and digested Taubes’s work were suddenly studying sucrose, fructose, and glucose, comparing them to each other and looking at their insulin effects.  ... The science on these different types of refined carbohydrates is still in its infancy, so we don’t really know if all carbohydrates play a role in obesity, diabetes, and heart disease, or if some types are worse than others.      {The Big Fat Surprise, Kindle Location 5447}
This was written sometime in 2013.  She acts like nobody ever did any research into this stuff before the Great Gary came on the scene and then they jumped into action!   Ludwig had been doing research on this before Gary wrote his articles, and could be described as a publishing machine by the time GCBC came out.  Let's not forget that he was prescribing what Taubes described as his own carb-restricted diet to his patients.   Nah .... Taubes started it all.

Another fun internet coincidence, I looked at PubMed and then Google Scholar, and here's one of the first (relevant) studies bearing Ludwig's name I could find:   High Glycemic Index Foods, Overeating, and Obesity (1999, his earlier work was not diet related, see for example 1987).  

Also from the Ludwig site, I found this appearance on Dateline NBC.  Feel free to watch the whole thing -- if you're into Evil Big Bread and lobbying, there's some footage for ya -- but I've just clipped out a few parts of this January 2004 show.




Not Atkins ... Sure about that? .... Sure!   

Oh yeah, that's the study that J.Stanton called "well controlled" that I discussed here.  When looking to see if the Ludwig video was on YouTube, guess who popped up talking about bread? 



Obesity Should Be Solved By Now!


Did you see the line of diet books there?  South Beach, Zone, Protein Power and Atkins.  The hey day.  Remember those days?  So we were told to cut carbs and we all did it!  And yet it didn't help in the long run.  No I am NOT talking about me, or you, or anyone else individually.  I'm talking about the American people, because that is who Taubes is talking about.   At the bidding of Ancel Beelzebub Keys, life-force sustaining saturated fats were stripped from our diets and replaced with killer white bread topped with cocaine sugar.   Why, oh why, didn't we all keep doing the Atkins thing?  Evil Bread?  Did you note in my clip that the Bon Appétit lady talked about being raised on white bread?  I think its safe to say she was raised in the 1950s.  

They also included The Zone amongst the LC diet books.  Ludwig's version of low-GI in 1999 was Zone macros (30P-30F-40C) so I'd say Sears' endorsement of Ludwig is appropriate, but that diet really isn't low carb -- except that it IS by comparison to what Americans have eaten for, like, ever (we're not going there to the Native Americans today, but LC for most of them as well).   

Ludwig has a pretty famous 2007 study where those with higher-than-median 30-min OGTT insulin levels fared better on his low-GI diet, but overall, there was no difference in weight loss between groups.  Again, we're talking recommendations that would be prudent to make to the benefit of the majority of a population, not specific individuals.  Taubes is gunning for sweeping change to counter a NON-EXISTENT culprit.  


Fast Forwarding Thru to NuSI


  • 2008 Eades' blog is tops, Taubes rises to fame in cultosphere
  • 2009 Low Carb is da bomb, Mark Sisson throws his hat in the ring blaming insulin
  • 2010  Cracks in the hypothesis start to widen and ... one by one adherents begin to jump ship ... An anonymous bunny eared blogger reads some old references and finds some disturbing errors and inconsistencies.  Gary Taubes starts blogging.
  • 2011  A disasterous year for TWICHOO.  WWGF is a relative flop for the great science journalist. Taubes tanked on Oz.  Many more defections ensued.  Stephan Guyenet kills TWICHOO in front of the first crowd of "ancestral health" enthusiasts. 

NuSI is Born  


The year 2012 began with a very strange publicity stunt.  A petition, started by Peter Attia, with Gary Taubes and cosigned by a veritable who's who of anybody left in low carb.  Against a food?  A company?  No, against Tara Parker Pope of the NYT for daring to write that losing and maintaining weight loss is difficult.  If ONLY she would just go low carb ... right?

The formal announcement about the formation of NuSI came sometime in late summer/fall of 2012.  To much fanfare, they were going to do GOOD science.  They set that bar very very high.  You see, bad science was any study that was too small OR too short OR free-living OR failed to manipulate carbohydrate levels as the macronutrient of interest (not much concern over controlling calories but ...).  This bad science would, by the way, include all of that rigorous Atkins-funded work Teicholz presents as top-of-the-line rigorous research.   I blogged about NuSI's ambitions and such here.

So the formation of NuSI went quietly along.  Every now and then Gary Taubes would pop his head up to write an article here or there.  Each of these articles was the same old same old, but with the new twist that NuSI was formed to fix it all!  


There's a Point Here .... Ludwig


So I wrote the Will NuSI Clear the Bar? post last August NuSI was just unveiling the research they were going to fund.  The post talked about another study, but they are about to begin (presumably recruiting) a new study in Boston, led by ... drumroll ... David S. Ludwig.  

The same scientist who was not all that fond of Atkins is all aboard the NuSI train and heading up a new and different kind of *real science* study thanks to a generous hedge fund billionaire.  What kind of real science?  The stuff that will answer for once and for all what the cause of all this obesity and disease is?  Let's look at this amazing new study shall we?

Current research and public health policy on obesity is largely based on the hypothesis that the fundamental cause of the condition is an energy imbalance between calories consumed and expended. By this hypothesis, the interaction between diet and body fat is determined by the caloric content of the foods consumed, while the macronutrient content of the diet (the proportion and type of carbohydrates, fats and protein) has no meaningful effect. This is often summed up by the assertion that a “calorie-is-a-calorie,” shorthand for the hypothesis that a calorie’s worth of protein has an equivalent effect on the accumulation and storage of fat in the human body (on “adiposity”) as does a calorie of carbohydrate or a calorie of fat. An alternative hypothesis is that the macronutrient composition of the diet influences adiposity through its effect on the hormones that regulate uptake of fat (technically “fatty acids”) by fat cells and their subsequent mobilization and use for fuel (that is, oxidation).

So we are going to do a 6 month metabolic ward study where 100 subjects will be randomized to two groups and fed isocaloric diets of 20% protein while half the subjects get 20% fat and 60% carb and the others 20% carb and 60% fat.  Food quality will be similar in terms of real, minimally processed foods.   

Oh sorry, that's not what they plan to do with 150 subjects randomly assigned to three groups of 50 ...
Phase I:  Standard American weight loss diet, 12 weeks, all subjects
45% carbohydrate, 30% fat, 25% protein; 40% below subjects’ calculated caloric needs for weight stability, minimum 1,200 kcal (“calories”) per day
For the first 12 weeks, participants in the study eat a diet modeled after what the average American eats, but at 40% below their calculated energy needs (by doubly labeled water). During this period, they are expected to lose 12% of their baseline weight.
Why are we not doing the weight loss phase on various different diets? I thought reducing calories was a failed weight loss approach. Why are we expecting them to lose 12% of their baseline weight? It's not the quantity of calories, it's the quality. How is this going to tell us anything about hormonal effects of fatty acid accumulation in adipose tissue. Hmmm?????

Phase II: Maintenance Diets, subjects randomized to one of the following diets, 20 weeks.
Low-fat:  60% carbohydrate, 20% fat, 20% protein;  Diet is rich in vegetables and whole grains and limits sugars and red meat.
Low-glycemic index:  40% carbohydrate, 40% fat, 20% protein (glycemic index 30-35); Diet replaces some grains, especially refined grains, with slowly digested (low-glycemic index) vegetables, legumes, and fruits.
Very low-carb: 15% carbohydrate, 65% fat, 20% protein;  Diet severely restricts carbohydrates and replaces them with fat, but keeps the carbohydrate load high enough to avoid ketosis.
For all diets:  caloric load continuously adjusted to maintain weight stability 
All meals are provided to the participants and they are closely monitored to assure that they eat all that they’re given. Throughout this 20-week period, participants are weighed daily. If their weight fluctuates, the caloric content of their diet is adjusted upward or downward to compensate, while always staying within the macronutrient prescription of their assigned diet. The goal is to ensure that the participants remain weight-stable, with less than 2 kg of total change, over the 20 weeks.
After the 20-week weight maintenance phase, the participants remain on their assigned diets, but are allowed to eat as much or as little as they like for 2 more weeks. The amount of food they eat is then quantified.

Again I ask why the calorie adjustment? Shouldn't we do each diet at the weight maintaining calories (there's that word again, funny how you can't get around it) and see who maintains, loses or gains? But first I ask, does this study sound familiar? It should, it is somewhat a repeat of the Ebbeling/Ludwig study from 2012. They are fixing a few things (like controlling for protein), but ...   From What we really learn from Ebbeling et.al.:  I really hope they plan on addressing the differences if any between intake and doubley-labeled water expenditures before wasting all this money.  Either there's still a lot of cheating going on despite the near-metabolic ward (though still free living) conditions, or the "state of the art" has some problems that could render any seemingly meaningful results a wash.

This study hardly seems groundbreaking is the major point.  Sure, if it turns out well we could learn some things the last one didn't tell us.  There are more subjects for a longer time frame vs. smaller group/cross-over study for shorter periods.  

But lets assume this goes entirely as planned.  And Gary Taubes is right.    As with the first study, the subjects will lose over 10% of initial body weight on a relatively high carb (45% is now "standard American weight loss diet?) high protein, low fat diet.  This is taken as a given, and yet is in opposition to TWICHOO.  What does it tell us that the researchers are even doing this?  Weight loss has been studied to death.  This is new?
The study will provide insight into the effects of dietary macronutrient composition on adiposity during enforced weight maintenance. Differences in voluntary food intake over the final 2 weeks of the study will provide insight into the effect of diet composition on appetite and hunger during weight maintenance.
I don't really see how.   Like I said, even if this goes as planned.  Depending on initial intake, reducing calories to 60% baseline (for example from 2500 to 1500) is steep and in the last study they then increased calories to maintain the reduced rate.  That's a lot of adjusting but maybe their closer to 2000.  Then 5 months switching diets -- in the case of VLC the most radical of all.    In the end this is a free-living study so even if there is a 300 cal/day difference by the end of 20 weeks, as was the reported differential the last time,  there can be no definitive conclusions.  

If they determine energy expenditure by the caloric intake, well, here I thought one of the reason calories don't count is that they are inaccurate anyway?!   That's more a minor point, but just to demonstrate that the arguments about CICO won't go away, especially since no matter how well monitored, this remains a free-living study.


But ... The Funding ...


One of the things Teicholz laments in her book is the lack of interest by the NIH in funding research on the Atkins diet.  This is why researchers had to basically have their arms twisted to accept funding from the Robert and Veronica Atkins Foundation.  
“When an unscientific fear of dietary fat pervades the culture so much that researchers who are on study sections that provide funding will not allow research into high-fat diets for fear of ‘harming people,’ ” as we’ve seen at the NIH and AHA, “this situation will not allow science to ‘self-correct.’ A sort of scientific taboo is created because of the low likelihood of funding, and the funding agencies are off the hook because they say that researchers are not submitting requests for grants.” While Volek and his colleagues have long urged the nutrition mainstream to take a “more unbiased, balanced” approach to the low-carbohydrate diet, they remained reluctant to recommend the regime to the entire American population, because it had not yet been subject to a long-term clinical trial.  {KL 5382}
Teicholz goes on to discuss the Israeli study headed by Iris Shai (Teicholz's discussion of which is well documented here).   In usual name-dropping fashion, 
Meir Stampfer, said that she had initially planned to include only the first two arms. After hearing Eric Westman give a talk at Harvard in 2004 and reading some of the recent low-carbohydrate trials, however, she decided to include the Atkins regime as well. XX  {KL 5396}
The discussion of Shai, in this context of the frustrated researcher unable to get funding to text the diet, is rather suspicious in its use of footnotes.  Rather than discussing all of the studies that had included an Atkins-style diet, or at least summarizing them, 

Given the context of funding or lack thereof, especially with her insinuations of bias in the NIH and AHA, footnote XX is Teicholz's way of hiding key information in plain site.  That information being:
XX: For this reason, the study was funded in part by the Atkins Foundation.   {KL 5772}
I have mentioned this before and will stress it again.  The footnotes of this nature are included at the end of each chapter.  In the electronic book, they are at least hotlinked so that the reader can click, read the note, then click back to the text.  In the hardcopy form, the reader would need to find the last page of the chapter and physically flip back and forth.  It is doubtful most read these footnotes.  One is left with the impression that there was only one trial that included the eminent Meir Stampfer (identified as a Harvard nutrition professor).  The discussion finishes with mention of two more longer term studies as evidence of the safety of the diet and that Westman, Volek and Phinney had concluded the diet had reached the threshold to be "recommended to the public more broadly".   This statement is also accompanied by a footnote:
XXII: In 2010, Phinney, together with Volek and Westman, wrote a new Atkins diet book called The New Atkins for a New You: The Ultimate Diet for Shedding Weight and Feeling Great (New York: Touchstone, 2010), which sold more than half a million copies in two years. Phinney and Volek also self-published two books on the low-carbohydrate diet.   {KL 5783}
The chapter -- clearly erroneously titled Why Saturated Fat is Good For You -- moves on to hail the awesomeness that is Gary Taubes:
... whatever scientific progress has been made toward our greater understanding of carbohydrates generally in recent years has clearly been due to Taubes’s work. “This has been his most important contribution to the field,” said Ronald M. Krauss, .... For a journalist, it was an astonishing coup in the world of science. In 2013, Taubes became one of the rare journalists to write a peer-reviewed article for the highly respected scientific publication, the British Medical Journal. Yet given the stranglehold that Keys’s ideas have held on nutrition researchers for so many decades, it is perhaps inevitable that an alternative hypothesis had to come from an outsider. XXVI   {KL 5471}
XXVI: In 2012, Taubes and the doctor Peter Attia founded a not-for-profit group called the Nutrition Science Initiative (NuSI) with a $ 40 million grant from the Laura and John Arnold Foundation. It aims to conduct high-quality scientific research on issues that the NIH and AHA have been reluctant to fund. ...  {KL 5795}
Leaving aside Krauss' own NIH/AHA cred, according to Ludwig's NuSI bio:
Dr. Ludwig has received 16 years of continuous funding from the National Institutes of Health, totaling over $25 million in grants and has published an astonishing 42 articles in New England Journal of Medicine (NEJM), Journal of the American Medical Association (JAMA), and Lancet.
And yet
... pioneering researchers of the Atkins diet continued to expand their work throughout the 2000s, conducting trials on a range of subjects: men and women, athletes, and those suffering from obesity, diabetes, and metabolic syndrome. XV  {KL 5366}
XV: A portion of this work was funded by the Robert C. and Veronica Atkins Foundation, which was set up in 2003 with a $ 40 million grant from Atkins to finance research following his death. Although these low-carb researchers were understandably reluctant to accept financing from a foundation with a clear agenda, there were no alternatives, since the NHLBI and AHA have long considered a high-fat diet too unhealthy even to be studied and have therefore funded no trials on it. ...   {KL 5748}
Yeah, it's not like any mainstream government bodies fund research into the low carb diet (often Atkins):  Foster et.al. NEJM 2003 (NIH) ; Dansinger et.al. JAMA 2005 (NIH) ; Gardner et.al. JAMA 2007 (NIH) ; Sacks et.al. NEJM 2009 (NHLBI & NIH) ; Foster et.al. Ann Int. Med. 2010 (NIH).  Of course none of these made the main text of the book because they failed to support Teicholz's assertions of Atkins=best, some made the footnote, others weren't mentioned at all.


But Does Funding Source Matter?


In general, yes and no.  By that I mean that ultimately the data are what they are, and barring outright fraud, that remains.  The peer review genre has been embarrassed a lot of late, and this is disturbing to say the least, but if the integrity of the data reported cannot be challenged, then it is what it is.   I think the most fair criticisms are of publishing bias -- that is, if the results don't support the funding body's objective, they are rarely published up.  This is not a good thing, but for private organizations it makes no sense to publish things up and there is no legitimate means to force this.  This is not about drug approvals and such where every bit of study is supposed to be divulged to the FDA no matter how negative.    
So yes, studies funded by particular industries are always subject to a little extra scrutiny ... but at the end of the day if all a critic of the study results can do is point a finger and say "but _____ industry funded", I'm actually more inclined to believe those results have merit.  After all, if the results were faked or wrongly interpreted, it should be child's play to pull it apart on the science.  

And here is where it got a little interesting because I searched The Big Fat Surprise for Ludwig's name ... after all, the Ebbeling/Ludwig study was published long before Teicholz rededicated herself to finishing her decade long endeavor.  No mention of that study at all.  But ... here Ludwig does show up ... as a co-author on a paper talking about funding sources and bias.
Lesser, Lenard I., Cara B. Ebbeling, Merrill Goozner, David Wypij, and David S. Ludwig. “Relationship between Funding Source and Conclusion among Nutrition -Related Scientific Articles.” PLoS Medicine 4, no. 1 (January 2007): 41– 46.  {KL 8840}
Teicholz's book is littered with insinuation and worse about industry and government organizations and the like.  Some may be worthy of note, some out right legitimately nefarious (but you'd be hard pressed to find the truth or the difference in this hatchet job of a book).  The conclusions of Lesser et.al. including Ebbeling and Ludwig?
Industry funding of nutrition-related scientific articles may bias conclusions in favor of sponsors' products, with potentially significant implications for public health.
Oh really?

In 2012, the various mainstream NIH funded Ebbeling/Ludwig study was published that showed two things using a direct measurement.

  • Cut calories and assist in compliance, subjects lost weight.
  • Keep calories stable and manipulate calorie "quality" and subjects remained weight stable. 
This conflicted with their indirect measurements showing energy expenditure was greater on the low carb diet.  They spun this as best they could to get the buzz.  Do you think Ludwig was already in talks with Taubes?  Friedman?  Maybe?  After all, in short order after the publication, Gary Taubes was back in his old stomping grounds at the New York Times penning yet another article about the same old same old.
What Really Makes Us Fat
...  But not everyone buys this calorie argument, and the dispute erupted in full force again last week. The Journal of the American Medical Association published the results of a clinical trial by Dr. David Ludwig of Boston Children’s Hospital and his collaborators. While the media tended to treat the study as another diet trial — what should we eat to maintain weight loss? — it spoke to a far more fundamental issue: What actually causes obesity? Why do we get fat in the first place? Too many calories? Or something else? ...
... What was done by Dr. Ludwig’s team has never been done before. First they took obese subjects and effectively semi-starved them until they’d lost 10 to 15 percent of their weight. Such weight-reduced subjects are particularly susceptible to gaining the weight back. Their energy expenditure drops precipitously and they burn fewer calories than people who naturally weigh the same. This means they have to continually fight their hunger just to maintain their weight loss. ...
... The results were remarkable. Put most simply, the fewer carbohydrates consumed, the more energy these weight-reduced people expended. ...  On the very low-carbohydrate diet, Dr. Ludwig’s subjects expended 300 more calories a day than they did on the low-fat diet and 150 calories more than on the low-glycemic-index diet. ...

There's just one problem, throughout these remarkable findings, the subjects didn't gain or lose weight and the individual results were ALL over the map.  Wild swings, etc.  (As an aside, an article discussing food Calories and science that doesn't mention Atwater is just a disgrace.  Period.  }
If we think of Dr. Ludwig’s subjects as pre-obese, then the study tells us that the nutrient composition of the diet can trigger the predisposition to get fat, independent of the calories consumed.



Only they weren't pre-obese and they didn't gain weight while calories were held constant.   But here's the kicker:
Dr. Ludwig’s results are by no means ironclad. The diets should be fed for far longer than one month, something he hopes to do in a follow-up study. As in any science, these experiments should be replicated by independent investigators. We’ve been arguing about this for over a century. Let’s put it to rest with more good science. The public health implications are enormous.

Within the next two months or so ...


... The NuSI funded study, lead by a researcher who is now authoring editorials in support of Gary Taubes hypotheses with a member of the funding agency, will get under way.

Follow the money.  This stinks.

Swedish Council on Health Technology Assessment
Dietary treatment of obesity
A Systematic Review
Weight loss in adults.

"A range of advice on alteration of eating and drinking habits can result in obese individuals losing weight or reducing their waist size. In the short term (six months), advice on strict or moderate low carbohydrate diets is a more effective means of achieving weight loss than advice on low fat diets."

"In the long term, there are no differences in the effect on weight loss between advice on strict and moderate low carbohydrate diets, low fat diets, high protein diets, Mediterranean diets, diets aimed at achieving a low glycaemic load or diets containing a high percentage of monounsaturated fats."

"Advice on increasing the intake of dairy products (primarily milk) or reducing the intake of sweet drinks may also lead to weight loss.

SO - Sweden is NOT recommending a low carb diet - another internet lie.

William Lagakos, Ph.D.

Dr. William Lagakos received a Ph.D. in Nutritional Biochemistry and Physiology from Rutgers University where his research focused on dietary fat assimilation and integrated energy metabolism. His postdoctoral research at the University of California, San Diego, centered on obesity, inflammation, and insulin resistance.

"If you’re trying to gain weight, avoid toxins (dietary or otherwise): 1) to ensure a high ratio of muscle to fat mass; and 2) because some of those toxins may be stored. On the flipside, if you’re trying to lose weight, avoid toxins (dietary or otherwise) to prevent insulin hypersecretion which could decrease the rate of fat loss and slow down your progress."

Jane Karlsson said...

The Ebbeling/Ludwig paper showing the more carbs you eat the less energy you expend has a serious flaw. According to an analysis by Don Matesz, the high carb diet had a lot of refined carbs.
http://donmatesz.blogspot.co.uk/2012/06/low-fat-diet-suppresses-metabolism.html


Refined carbs lack micronutrients needed to activate enzymes of carbohydrate metabolism. All subjects in the study were given a micronutrient pill, but the ones on the high carb diet probably needed more than the others.

The younger generation is eating more meat. They are dying even before their centenarian forebears do. In fact, because of this shift in dietary pattern, Okinawa is leading the nation of Japan in obesity and no longer carries the banner of longest lived region. The younger ones are dragging down the lifespan averages.

A Web of Doubt: Science Friday

They say you shouldn’t believe everything you read, and that goes double for the Internet. Online, information may be cheap, but it’s also unreliable. You can’t trust the people, you can’t trust the articles, and you can’t even trust Wikipedia! In his book Virtual Unreality, author Charles Seife exposes the shadowy world of the Internet.

In reading up on this for the past few days, I ended up consuming unhealthy quantities of Lyle McDonald and Anthony Colpo. And it was a Colpo article I read that immediately came to mind when I read the Woo lady's comments. Here is an article where he demolishes the NHANES data and most of the underpinnings of Taubes' theories, and indeed the theories and assumptions most of the low-carb community starts with.

http://anthonycolpo.com/why-you-cant-trust-nhanes-or-gary-taubes-robert-lustig-to-accurately-report-calorie-carbohydrate-fat-intake-trends/



Wish I'd read that a long time ago...even though it is rather lengthy. It's needed. Grab yourself a snack and a drink and go to town on that one...

carbsane said...

Duh. This guy is horrible. The record is clear that we didn't just add more of these things, and the message to eat less is always on the table. Or did I miss that.


It's the Bailors that are fraudulent. Thanks Dr. Fung!

MacSmiley said...

Excellent analysis by Don. Key point: The "LF" group's diet contained less fiber than the LG group's diet did, which had more fat. That means the LF group must have been eating more refined carbohydrates than stated in the alleged design of the diets. The problem is not low-fat per se, but the lack of unrefined plants in studies like these.

MacSmiley said...

Exactly. No one can look at MyPlate compared to the Food Pyramid and not see replacement advice. That's the problem with the TIME cover. Americans will simply add butter to what they already eat and get even more obese, not less.

Glenn Dixon said...

I don't care how much attention Taubes got from his NYTimes article, I still can't see how Knopf justified the $750,000 advance. He did, however, have another book in 1993

http://www.amazon.com/Bad-Science-Short-Weird-Fusion/dp/0394584562



The proposed NuSi study is interesting for many reasons, but I'm struck by how short it falls from the ideals touted by low-carb advocates. Every time it is pointed out that studies don't support their low-carb theory, the advocates say something like "Well, yeah, of *course* big food won't allow any proper studies to be funded. Just wait till someone does a study showing that a low-carb diet produces weight loss compared to a low-fat diet with the exact same calorie count! Just you wait!"


So here's their big chance, and all we get is "keep the weight the same by adjusting the calories as needed???" Seriously?

StellaBarbone said...

Oh, but which toxins am I to avoid?

Kade Storm A.K.A. Hedonist said...

Imagine taking people from a population that is generally consuming fat on the moderate to high side of the spectrum. Then consider what we know and understand about the Randle cycle, and more specifically, the Randle effect and its lingering impact on oxidative metabolism and blood lipids; that is, just how limited certain 'fat-adapted' people are when it comes to handling large amounts of glucose, which can last for weeks or even months. Even outright healthy individuals from such populations aren't guaranteed to be ideally adapted to such a low fat intake where carbohydrate is increased at the expense of fat. Their glucose metabolism isn't suited to such an intake over a 4 week period, and when one tops it off with the fact that they lost weight--ran on more elevated fatty acids--the problem is compounded further.

Wuchtamsel said...

Traditionally the function of journalism was to act as a filter, to separate the important stuff from nonsense and BS. The TIME cover is THE example how this function got lost, if it ever was there.

Kade Storm A.K.A. Hedonist said...

I am quite certain that he was being facetious with the comment.

I mean, the comment caricatured such classic appeal to anecdote that is common in certain circles when it comes to Okinawan denials. "But, but... population studies can't be right, because my friend's, mom's, cousin's old college room mate was there for a weekend and ate tons of [insert contradictory contention]."

Jane Karlsson said...

Here's what Taubes says in What Really Makes Us Fat about the paper.
'One diet was low-fat and thus high in carbohydrates. This was the diet
we’re all advised to eat: whole grains, fruits, vegetables, lean sources
of protein.'

Here's what the paper says.
'The low-fat diet, which had a high glycemic load, was designed to reflect conventional recommendations to reduce dietary fat, emphasize whole grain products, and include a variety of vegetables and fruits [ref 17].'

Here's what ref 17 says.
'Consume a variety of fruit, vegetables, grains, low-fat or nonfat dairy products, fish, legumes, poultry, and lean meats.'

Nothing about WHOLE grains.

Jane Karlsson said...

Yes that Colpo article is first rate. There is a huge problem here. When he's good he's so good you get fooled into thinking everything he says must be good. I have a long standing argument with him about whole grains. He thinks refined grains are better, and he produces reams and reams of stuff supporting his position which to me do not support it at all. But who is going to wade through it? Nobody. So the idea that whole grains are bad for you is what nearly everybody believes. Including Taubes, of course, which is ironic considering Colpo and Taubes are enemies.

Paleo Nouveau said...

A quick comment. "Experts?" 11 "experts!" Hite, Naughton, Feltham, It's the Woo, Stanton & Bailor constitute experts in what universe? Even Taubes. What serious researcher or scientist would consider them even slightly approaching any level of "expert?"

Why would we dismiss Ancel B. Keys with his proven background & consider these lay people experts? Just because they call themselves that or because their other "bro scientists" keep high fiving them over the internet? Why follow the science? Outrageous claims from the internet experts seem more plausible than science most of us can't understand!!!

Kade Storm A.K.A. Hedonist said...

Industry trend. Now we merely aim to sell people what they want to read. At one point, they wanted facts, now they simply want their preconceptions and biases reinforced.

Glenn Dixon said...

Just searched his site for grains. Doesn't seem to have any single article on the topic, but read one rambling response to an email. Lots of words, very minimal references. Similar for alcohol. Oh well, at least we'll always have NHANES. lol

David Pete said...

Winner!

Glenn Dixon said...

The 'bacon specialist' phenomenon makes me chuckle. But Seife is missing the point. Most of what he points out are faked likes and follows. Much more pernicious, IMO, are the fake personas which are actively used for posting content to sow doubt about things like climate change or politics.

John Smith said...

To be true expert one must understand nutrition at the quantum level, molecules of different macronutrients have different number of isotopes which initiate Higgs boson reaction if more than 5 isotopes, setting free quarks which then collide with free radicals in bloodstream thus shortening length of telomeres. None of the so-called "experts" knows the first thing about particle physics.

MacSmiley said...

But Taubes's brother is a Haaavaaad professor. Doesn't that count?

MacSmiley said...

He does point out the way those on the fringe have a means of influence they did not have before, fake people aside. It's later on in the interview and less amusing than the bacon algorithm.

Jane Karlsson said...

The problem is that he doesn't know much biochemistry. He says for instance that whole grains are not antioxidant rich foods, but his list of antioxidant nutrients does not include manganese or copper, which are high in whole grains and which activate the most important of the antioxidant enzymes. This is a HUGE mistake.

Nigel Kinbrum said...

You can't beat a jolly good low-carb circle-jerk ;-) :-D

carbsane said...

Exactly! They are doing other studies -- a large one with half eating 10% carb ad libitum and the other eating 10% fat ad libitum -- free-living for a year. When free-living compliance with FAR less extreme dietary interventions has been so pathetic, what do they hope to show here? Neither intervention would be practical advice for the general population anyway.

Lighthouse Keeper said...

That's what Razwell has been saying recently - gold standard quantum quackery. One wonders what a RAZWELLIAN food pyramid would look like if you could actually see it (access to an electron microscope required).

I consider white rice to be a whole (i.e. intact) grain. Is 100g/day (dry weight) of white Basmati rice going to kill me?

carbsane said...

Yes, he's spot on with everything he's written regarding the so-called metabolic advantage of LC diets and calories. I'm pretty confident recommending any AC article on these matters.


I haven't read his cholesterol book. His most recent book on grains began as a lengthy guest post or few on Matt Stone's blog. I read part of one when it came out but then Matt basically went to a newsletter format for the blog and the articles are gone and were turned into a book.


I've not read it, but several have pointed out that he seems to have fallen into the trap others have regarding health claims vs. viewing the foods on their merits. IOW, that "whole grains" aren't magical wells of health, longevity and freedom from obesity and disease ... IOW that "healthy whole grains" is a term up for legitimate debate, it doesn't mean they are harmful either. If anyone's read it and cares to fill in with a synopsis, feel free!

Nigel Kinbrum said...

Krauss/Dreon et al are guilty of using a 50/50 complex/simple carb mixture to make "carbohydrates" look bad (in terms of LDL particle size). The complex carbs could have been maltodextrin (GI = 100 on the glucose GI = 100 scale), for all we know.

37.5%E as sugars isn't going to do anybody's LDL particles any good!

Awful Will said...

Here's my favorite section:

She quotes Walter Willett of Harvard University and John Farquhar of
Stanford University-both of whom were interviewed and quoted extensively
by Mr. Taubes in the Times Magazine piece-as saying they felt betrayed
by the article. “I was greatly offended at how Gary Taubes tricked us
all into coming across as supporters of the Atkins Diet,” Mr. Farquhar
told her.

Awful Will said...

ItsTheWookie is an "expert"? HAHAHAAHAHAAAAAAA!!!!

carbsane said...

I see he's commenting over on Wooo's. This is a test of her sincerity as Razz is a perennial troll. As if one needed it, he identified himself. So I guess the Italian Wooo doesn't care about ethnic slurs like "dago" that Razwell has a history of using so long as nobody dare suggest she looks her age.

carbsane said...

I honestly don't know what gives with this guy. He's obviously bright but he hasn't done anything since his postdoctoral research and does not appear to work for the outfit he used to have on his FB page. That research was on fatty acid binding proteins in the gut and while I'm not a regular blog reader, I don't think he's blogged on that topic.


His calorie book is the worst of the bunch. Worse, even than Calorie Myth. Makes no sense.

El-bo said...

>> "You can't beat a jolly good low-carb circle-jerk ;-) :-D " <<


especially when done real slow so as not to call for too much muscle glycogen :)

MacSmiley said...

Contacted last week, Jonathan Segal, the Knopf editor who acquired Mr. Taubes’ book, said he wasn’t concerned that his new author was drawing heavy criticism before the book is even written. Differing opinions, he said, were inevitable: “Come on, let’s get with the real world, man. It’s a free country: First Amendment.”

[...]

As for due diligence in researching Mr. Taubes’ background, Mr. Segal said that “Gary was mentioned by a couple of writers I admire enormously.” He added that “I went online and got Gary’s pieces in Science magazine.”

So, according to this article, Segal made his decision based on Taubes's rep as a debunker of conventional scientific wisdom. Forget that cold fusion was never established as "conventional".

Segal claimed he was contracting for a book on the history of nutritional science and disavowed any connection to the NYT article, but Taubes was up front about his pro-saturated fat stance being a prominent theme of the book. Segal just wanted a "hot property".

Mr. Segal said the final checking of facts was up to the author.

Seriously? When lives could be in the balance ??

Nevertheless, A factually accurate GCBC would never have sold a single copy.

Controversy over facts, as Evelyn stated.

It's one thing to debunk low carb gibberish. But when a personal trainer try's to take on half a centuries science on atherosclerosis he generally comes off as rather foolish.

Jane Karlsson said...

I hope so, Nigel. Anyone who considers white rice to be a whole grain deserves no less.

I expect you think the veggies you eat will supply the micronutrients you need for processing the carbohydrate.. Well they probably won't. A 'strong linear association' has been found in China between white rice consumption and diabetes risk, and veggie intake correlated positively, not negatively, with white rice intake.
http://apjcn.nhri.org.tw/server/APJCN/21/1/35.pdf

Jane Karlsson said...

Well he does do a lot of homework, and he does his best to understand the biochemistry but it's just too complicated. It really is a nightmare. It took me 20 years of studying metabolic pathways to get a grip on them. One problem is that the textbooks often do not tell you which enzymes are activated by which micronutrients. I think this is the main reason people think it doesn't matter if you remove micronutrients from carbohydrate foods.

David Pete said...

For the record, I hope white rice does not kill Nigel or anyone else, no matter what they consider white rice to be

tomas said...

Josh,
I did check them there before going to web archive. 180DH still shows a "No results" message as I type this.

Anyway I still wonder if AC is going to writing more stuff for Matt Stone, he had been listed among site authors on the old 180 site

Jane Karlsson said...

I've been wondering about him too. Who is paying him? Same people who pay Taubes? The mind boggles. I read a bit of his book and thought this is not someone who had a brilliant idea and is pursuing it, it's someone who is being paid to do something they don't really believe in.

Jane Karlsson said...

It's probably killing people in Japan. Fukushima will have raised the micronutrient requirement. It freaks me out that the authorities are not telling people to eat brown rice.

Nigel Kinbrum said...

From your link:-
"Rice has high glycemic index (GI) and is related to the risk of type
2 diabetes mellitus."
Generalisation, much? The GI of cooked rice depends on rice variety, cooking time and subsequent refrigeration (which forms RS3). Basmati rice is very-long-grain & high in amylose, and I don't "cook it to death". What variety of rice do the Chinese eat? The study doesn't say.

The word "whole" has two definitions: 1) "intact" and 2) "containing all of the constituent parts". I prefer 1), as I consider grain dust (whether wholegrain or not) to be unhealthy, as per http://nigeepoo.blogspot.co.uk/2010/02/problem-with-whole-grain-cereals.html

Jane Karlsson said...

Sorry Nigel. 'I hope so' was a joke. I get carried away sometimes.

Awful Will said...

I had once looked into what they traditionally had in Japan, assuming that it maybe was similar to the short grain type as found in most Chinese restaurants today. But I couldn't find a definitive answer.



South China, being so vast, probably has many more varieties.

Awful Will said...

That's why I'd heard of using molasses (blackstrap?) as a sweetener, because of the minerals.

Nigel Kinbrum said...

I know! I'm used to your dry sense of humour, remember? :-D

Nigel Kinbrum said...

I think that short-grain rices are lower in amylose (slow to hydrolyse) and higher in amylopectin (fast to hydrolyse). I didn't realise that Basmati rice is aged to give it a distinctive flavour.

When I was younger, I hated rice, as it was the short-grain stuff "cooked to death", which was pretty much tasteless.

Awful Will said...

carbsane, here's a good reason to resume with the action figures:

https://www.youtube.com/user/drsupaflykt

No wonder she says that carbs are addictive like cocaine. She named herself there on an early youtube account after a 1970s violent drug dealer from the movies.



In pop culture, violent drug dealers are cool because they be fightin' da man and breakin' da rules... just like lo carbers.

Awful Will said...

Yes, short grain is typically higher GI with more amylopectin. Do you have Uncle Ben's there? It's tested to be low GI.

Nigel Kinbrum said...

We do, but I'm using Kohinoor Extra Long Basmati Rice (XL) Aged to perfection. It was £4.50 for a 2kg bag in Tesco. It's more filling than I expected. I cook it al-dente.

carbsane said...

Just sticking this in here somewhere: Some processing of grain has been going on for eons. The non-buffalo eating Native Americans and buffalo eating ones alike consumed the seeds of wild grasses -- aka grains. The preps I've seen detailed include various means of removing the outer coating. This predates the declines of these cultures as they've transitioned to more "Western" foods.

Awful Will said...

I think a person could simply and easily eat really low GI by following eah meal with psylium. I assune yu've seen the gel that it forms when you let it stand for a few minutes after mixing with water.

However, I'm not sure if stomach contents mix, or if they stay layered like a parfait. If stomach contents don't mix without a lot of body movement to prompt that, then it's not so easy after all.

carbsane said...

Here in my area I shop a lot at Trader Joe's. Their white basmati rice is da bomb and comes in a resealable ziploc baggie (nice extra). Tis a little more than rice in bulk, but we don't eat *that* much to justify storing it in bulk in my limited space.

It cooks up fast, but here's what I really like -- it seemingly absorbs and absorbs more and more liquid without going mushy, and nice long grains! I've taken to only adding it to soup I'm planning to eat fresh (as opposed to freezing it) because it turns them into stews :)

carbsane said...

Your stomach mixes everything up but good :-)

Awful Will said...

Thanks. What if I were paranoid about phytates inhibiting mineral absorption, so right before a meal I take a mineral tablet, then have a lot of non-phytate food, then finish with a lot of beans?

Would the mineral supplement tablet make it out of the stomach quickly? Or would the exit valve stay closed and so the tablet would mix with the beans anyway?

Awful Will said...

What's the story on arsenic in rice? Is that a true lie, or not? Or will it take a while before the truth is known for sure?

StellaBarbone said...

Rice takes up heavy metals well. Arsenic concentrates in the hull, so Nigel's white rice is lower in inorganic arsenic. California rice is lower in IA than Louisiana and Texas rice, but the FDA doesn't consider either source to be a particular problem. They do recommend that infants not be given rice cereal every day, but don't have recommendations for older children and adults.

Kale or corn
dogs, bananas or beer, a calorie is still a calorie. At least, that’s
what dieters have been told for the past half-century. Now, experts
don't agree

“By and large, we’ve been taking an accounting approach to weight loss,” says Dr. David Ludwig, a professor of nutrition at the Harvard School of Public Health. By that he means, health scientists have traditionally focused on the number of calories coming in versus the number of calories going out. But there are a lot of problems with that approach, he says. For one thing, it’s really tough to accurately keep track of your daily calorie intake. “Being off by just 100 calories a day could add up to a hundred pounds over a lifetime,” he says.

If burning more calories than you consume would keep you skinny, a low-fat diet should be the answer to all your diet prayers. That’s because, compared to protein or carbohydrates, fat contains roughly twice the number of calories, ounce for ounce. But Ludwig says low-fat diets have proved ineffective when it comes to losing weight. “Mediterranean or low-carbohydrate diets outperform a low-fat diet every time, and that
wouldn’t be true if calories were the only measure that mattered,” he adds. (Mediterranean diets and others like the now-trendy Paleo diet are both high in fat, comparatively speaking.)

In reality, Ludwig says the body responds differently to calories from different sources. “Your weight is regulated by a complex system ofgenetic factors, hormonal factors, and neurological input, and not all calories affect this system the same way,” he explains.

As for fat: “Some naturally high-fat foods are among the most healthful we can eat in terms of promoting weight loss and reducing risk for diabetes and heart disease,” he explains, listing off foods like nuts, avocados, and many types of fish. “If you’re counting calories, you would want to eat these foods sparingly because they’re dense in
calories. But they’re also very filing.”

Refined carbohydrates, on the other hand—like those found in white bread, cookies, crackers, and breakfast cereals—raise your blood’s level of the hormone insulin, which signals to your body that it needs to store fat cells. Also referred to as high-glycemic foods, these refined carbs pass through your digestive system quickly—which is why you can eat a whole bag of potato chips and feel hungry 15 minutes later, Ludwig says.

Dr. Richard Feinman, a professor of cell biology at the State University of New York Downstate Medical Center, compares insulin to a faucet handle. The more your blood’s amount of the hormone rises, the more the faucet opens and the more fat your body stores.

Feinman has looked at calories from the perspective of thermodynamics—or the laws that govern heat and energy. Like Ludwig, he says the idea that calories from different macronutrient sources would have the same effect on your body is silly. Put simply, it doesn’t make sense that “a calorie is a calorie” because your body uses the energy
from different foods in a variety of ways, Feinman explains.

The big lesson here is that people need to look at food as not just a collection of calories, experts say. By cutting out refined carbs and eating more protein and healthy fats, which help you stay full without triggering the storage of fat cells, “You can work with, as opposed to against, your body’s internal weight-control systems,” he says. “That
will make weight loss more natural and easy.” The best part: You can put away the calculator. No more calories counting

"The iron link between fat and heart disease was welded together in the 1950s in America where heart attacks had risen sharply. While smoking is now thought to have prompted the rise it was a scientist called Dr Ancel Keys who first postulated that there was a link between saturated fat and heart disease. When his first study was comprehensively dismantled by Jacob Yerushalmy, founder of the biostatistics department at Berkeley, instead of re-examining the evidence, Keys pushed back even harder and unveiled what became known as the “Seven Nations” study which published evidence from six countries in Europe and Japan showing a strong link between a high fat diet and heart disease.

Yet what has since emerged is that Keys had evidence from 22 countries and cherry-picked those that provided the most support for his hypothesis. He ignored nations such as France, West Germany and Sweden that had high-fat diets and low levels of heart
disease and focused instead of countries such as Yugoslavia, Finland and Italy, which had high-fat diets and high levels of heart disease.

A new book, The Big Fat Surprise: Why butter, meat and cheese belong in a healthy diet, by Nina Teicholz, revealed that Keys’ study from Crete, which he held aloft as an example of a healthy low-fat diet, drastically undercounted their fat consumption by conducting the study during Lent, when meat was traditionally set aside, and instead of focusing on the
diets of 655 men, he focused on only a few dozen. Keys’ flawed research was then quickly adopted by the American Heart Association, which in 1961 issued the first guidelines against saturated fat.

Our new fat-free diets have had unintended consequences. We now eat roughly 25 per cent more carbohydrates than we did in the past. The problem with overloading on carbs is they break down to glucose, which results in the body releasing insulin, which is very effective at storing fat. Studies now show it is diets overly high in carbs that are leading to obesity, type 2 diabetes and heart disease.

A word of warning, butter cream and cheese may be back on the menu but ca’ canny, they are still very calorie dense.

AsTeicholz writes: “Every plank in the case against saturated fat has upon rigorous examination crumbled away.” The health establishment insists on still standing on those planks, but for how long will they hold?"

MacSmiley said...

Potato chips have a lower glycemic load than pizza. Ludwig is forgetting his basic math. Feinman's another story.

The problem with junk carbs is palatability paired with lack of volume. I've eaten a whole bags of chips. However, by the end of the bag, satiety eventually kicks in. Never felt hungry 15 min later.

carbsane said...

OK that was just weird! LOL

http://chriskresser.com/is-starch-a-beneficial-nutrient-or-a-toxin

"If the argument is that starch isn’t safe for those with impaired
glucose tolerance, I concede that may be true in many cases. However, I’d like to point out that there’s some evidence that suggests starch may be safe in this population as well. For example, low-fat diets also cause fat loss (even without deliberate calorie restriction), though to a lesser extent than low-carb diets. And there are documented cases of people losing significant amounts of weight and improving metabolic parameters by eating nothing but potatoes. For example, Chris Voigt lost 21 pounds over the course of two months by eating only potatoes and not deliberately restricting calories. Furthermore, his fasting glucose decreased by 10 mg/dL (104 to 94 mg/dL), his serum triglycerides dropped by nearly 50%, his HDL cholesterol increased slightly, and his calculated LDL cholesterol dropped by a stunning 41% (142 to 84 mg/dL)."

" If Drs. Rosedale and Shanahan are going to advise us to avoid an entire class of food that has been eaten for a couple of million years by humans, the burden of proof is on them to tell us why that food isn’t safe. Evidence from roundworm experiments and biochemical/mechanistic speculation is not enough in the face of overwhelming evidence that starch and glucose are safe in the absence of certain existing health conditions."

Sorry Tomas, my mistake. You are right, those posts are no longer visible on the live site as they were taken down to be used as the basis for the Whole Grains Empty Promises book.

StellaBarbone said...

In my twenties, thirties, and early forties, my body's "internal weight control system" worked just fine. Then it stopped. My diet didn't change. I still ate plenty of fruit and veg, healthy fats, protein, non-simple carbs. What's the theory there? You know all that appetite controlling sat fat in cheese? More please! It sure doesn't make me want to stop eating.

I have three dogs; two fat, one thin, all the same breed. The fat one is always hungry. Give the skinny ones too many treats and they will skip a meal. They all get the same dog food. Why is the macronutrient blend controlling the appetite of the skinny ones, but not the fatty? My sisters-in-law live on a diet of hamburgers, spaghetti, and Entenmans pastries. They are very skinny. Why doesn't all that pastry screw up their "internal weight control system"?

What a bunch of bogus blather.

MacSmiley said...

Of course, I'm talking about a large bag, not those wimpy single serving thingies. Being still hungry after one of those is a given, but it doesn't take as long as 15 min.

MacSmiley said...

So does Cordain eat crabapples instead of McIntosh or red delicious?

I eat Granny Smith's myself

Except potato chips are really around 50; that's not high GI, it's low GI.

But why let such a crowd-pleasing theory get bogged down by simple facts.

Awful Will said...

Did you notice she commented on a video about string theory?

Come to think of it, maybe carbs are really composed of 9/10s dark energy. So a gram of starch really has 40 calories, 36 of which can't be detected. Now it all makes perfect sense.

MacSmiley said...

Granny Smiths actually have more sugar in them than most other varieties of apple. They just have more acidity as well. :-)

MacSmiley said...

Some women, not all. Erosion is not the lack of cardiac events, of course, but a different physiological pattern. This is because in many women, the plaque tends to be laid more uniformly around the lumen.

This is why women often have different cardiac event symptoms than men (though not always) and why their CAD often goes undiagnosed even with the usual diagnostic tools.

If one wants to argue everything can be critiqued. On the other hand this practice seems to further validate Keys point. If instead of fasting & abstaining from meat, dairy etc. they were eating high fat foods then I believe the study could be compromised.
If I'm not mistaken the study did not just focus on blood work for that period to make a determination on their health or markers.

carbsane said...

Hence my meme. You are allowed one Granny Smith apple per day on the 21 Day Sugar Detox. You see sugar is toxic and addictive, but its really that sweet taste that's the problem. Therefore the next time a scotch-drinking alcoholic tries to quit drinking, let him or her have only one mimosa per day instead. If you can't taste the alcohol, it won't be a problem.

Jane Karlsson said...

Very interesting. This pattern of fasting would correct mineral imbalances caused by too much meat and dairy, which are high in iron, calcium and zinc, and low in magnesium, manganese and copper. Seafood and whole plant foods don't have this problem.

The propaganda says we need more, not less, iron, calcium and zinc. So white flour has iron and calcium added, and many breakfast cereals have added zinc. In the US, white rice has added iron and sometimes calcium.

Magnesium, manganese and copper are not added to anything, despite mountains of evidence that deficiencies of these metals are a major cause of disease. Copper deficiency in heart disease for instance, and deficiencies of Mg and Mn in diabetes. Mn and Cu in Alzheimer's.

Iron overload has been found in all of these, and in much else too. Mn and Cu prevent the damage caused by excess iron. This is what Colpo missed, that whole grains are a major source of the minerals which prevent iron-dependent damage.

Jane Karlsson said...

Yes, full of minerals. Yummy. Actually not very yummy. Dark brown sugar is though.

Kade Storm A.K.A. Hedonist said...

Seems to have a very high ratio of magnesium and calcium to iron. Good stuff in my opinion, but whatever.

MacSmiley said...

ROFLOL!! Dark calories!!!!!! ARGGHHHH!

MacSmiley said...

Reminds me of a friend who had an alleged Candida overgrowth which of course is "caused" by sugar. She was told the only fruit she could eat was Granny Smith apples. Alt med FTW! ;-P

MacSmiley said...

Iodine deficiency is more likely an effect of less table salt. Most salt consumed in the US comes from processed food. That salt is not usually iodized.

Yes indeed. More support for Keys bashers.
Charles--these are remarkable, pertinent, important links you've once again provided to visitors of this forum. Thank you for posting them and for keeping up
this public service. Very much appreciated.

Kade Storm A.K.A. Hedonist said...

Not if those bashers want to keep a straight story.


Just imagine the train of thought... "Keys lied in his work as he omitted something very about the Greek Orthodox tradition of fasting when their diet is even more restricted. Majority of animal products are not allowed, and therefore, since Keys lied, we must consume more SAFA, steaks and eggs."

Jane Karlsson said...

Is iron really so critical for pregnant women? Two of the most common pregnancy disorders, gestational diabetes and preeclampsia, are associated not with iron deficiency but iron overload.
http://www.ncbi.nlm.nih.gov/pubmed/21709294
http://www.ncbi.nlm.nih.gov/pubmed/12193935

In all my years of studying the biomedical literature, I have never come across convincing evidence that the billions of people thought to have iron deficiency do in fact have it, in the sense of needing iron supplements. They appear to have multiple micronutrient deficiency, and need to stop eating micronutrient depleted food.

Much the same can be said for calcium. The western diet is higher in calcium than most third world diets, but we have higher, not lower, rates of bone fracture.

I think the term propaganda is actually quite appropriate. There is a well funded campaign to get all countries to add iron to their food. I know a Chinese scientist who is concerned about this because of the link he has found between iron overload and diabetes. China now has iron-fortified soy sauce, and he is trying to argue against it.

Nigel Kinbrum said...

"...a total of 180–200 days of fasting per year."
I may not be living any longer as a result, but it'll certainly feel like I am! ;-)

MacSmiley said...

Evelyn has just posted about this article, but I thought I'd quote the part of Henry Blackburn's commentary which pertains to the question of Lent and fasting days in the 7 Countries Study:

Events such as religious holidays and crop failures have an effect on what people eat at a given time and are part of the bigger picture of a community’s eating pattern. Avoiding variations in eating at different parts of the yearly cycle would have been the real “cherry-picking.”

Get basmati rice grown in India: reportedly little to no arsenic, as it's
not in their soils. [plus--it's glycemic index is lower than most, it cooks up easily and perfectly, and tastes great with a little butter, salt & pepper]. Brown or white.
