"The results were impressive. Those on the “Atkins” diet burned 350 calories more per day — the equivalent of an hour of moderate exercise — than those on the standard low-fat diet. Those on the low-glycemic diet burned 150 calories more, roughly equivalent to an hour of light exercise."
This was done with out exercising at all. Although this study is very small, it is particularly compelling because it was done in a controlled facility, feeding the study subjects every meal. This study could not have come out at a worse time for Marion Nestle who just wrote a book entitled "Why Calories Count".
"After hearing one of the authors being interviewed on NPR yesterday, I bought the Kindle edition of their book. Given their title, I was particularly curious about how they addressed the evidence that indeed calories don't count nearly so much as the type of food eaten and that the "calories-in/calories-out" energy balance paradigm represents a misunderstanding of the First Law of Thermodynamics (see the articles on MedPage Today entitled "Food Fight Over Whether Hitler Made Us Fat" and also "Food Addiction: Cheesecake-Eating Rats and Obesity as a Mental Illness").
In 2007, author Gary Taubes published a 600-page book (including 114 pages of footnotes and references) entitled Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health. This book amassed and described a virtual mountain of evidence based on biochemistry, metabolism, physiology, endocrinology, epidemiology and clinical research that leads to the conclusions that:
1. Obesity is a disorder of excess fat accumulation and not the result of energy imbalance, overeating or sedentary behavior
2. Overeating and inactivity are compensatory effects and not the causes of obesity
3. We don't get fat because we overeat, we overeat because our adipose tissue is accumulating excess fat
So what data and arguments do Nestle and Nesheim muster to counter Taubes' evidence and conclusions? First of all, they don't even do it themselves, rather they bring in a surrogate, Dr. David Katz, to make their case. And what does Dr. Katz have to say? As quoted by Nestle and Nesheim, Katz asserts that the result of an anecdotal "N-of-1" experiment conducted by a single individual eating a "Twinkie Diet" is sufficient to invalidate or refute the arguments made in two books summarizing hundreds of studies over many decades (Taubes more recently published a streamlined and updated sequel (Why We Get Fat: And What to Do About It) to his earlier book. Moreover, Katz is hardly an unbiased judge of the evidence because he profits from his own commercial "NuVal(tm)" and "Flavor Point" diets that, if Taubes is right, might not be so compelling an approach to healthy eating and weight control or be good for his reputation as a diet blogger on The Huffington Post.
The use of a surrogate with an undisclosed conflict of interest represents intellectual cowardice (or laziness) and dishonesty (or carelessness) on the part of the authors of "Why Calories Count." This hugely negative aspect of the book calls into question the authors' reasoning and objectivity with respect to other arguments and conclusions made in their book."
Maybe Gary Taubes, and Mack90 are on to something...
