- As usual, Chuck, when you post your tome, I end up at the library.
- Unfortunately for your thesis, I often find other articles,
- sort of swept under the rug by you, I suppose, that are more
- credible and opposite in their view in the same issues you
- cite. I'm sure your answer to them will be "they fudged their
- data", etc. Too bad the peer reviewers weren't so perceptive.
-
- For example, in the July 1992 Supplement to the Am J. Clin. Nut.,
- we find a whole section on "Cycle Dieting". Here is an article
- by Stunkard (famous obesity researcher) that studied cycle dieters
- quite extensively. (No, they didn't start 30 years ago before
- the dieters started their first diet, we'll have to wait 30 years
- for such as study, since 30 years ago no one paid much attention
- to the phenomena). Lo and behold, Stunkard found that there was
- no correlation between the number and depth of cycles and Lean
- Body Mass (contrary to what you've been saying), metabolic rate
- (contrary to what you've been saying), ability to lose weight
- on a new diet, etc. Yes, there was a correlation between BMI
- and cycle dieting, but that is what would always be expected,
- since thin people don't diet. It certainly doesn't imply that
- dieting caused the fatness. All of these women were fat before
- they started dieting. There was no evidence that they ruined
- their metabolisms by dieting, as you have been saying. This has
- been the conclusion of every study I've seen done on humans.
- Only your one or two rat studies have indicated otherwise, that
- I've seen. Another article in the same issue had the same
- conclusions.
-
- In the Oct 92 issue of the same journal, your theory that the
- obese violate the laws of physics was also shot down. When
- both fat and lean volunteers were overfed and their metabolism
- was studied using whole body calorimetry and their intake and
- exercise carefully accounted for, all of the weight gain was
- just as predicted. When they stopped feeding them too much,
- the weight loss also occurred just as predicted. There were
- no "magic" malabsorptions or fluctuations in thermogensis
- except that expected from increased body mass.
-
- In the same issue, another paper studied 204 obese women and found
- that, contrary to your theories, the amount they ate correlated
- with their level of obesity, and that the fatter ones ate more
- fatty foods and less protein and carbohydrates, as a percentage
- of total intake.
-
- I'm sure you'll be discussing these papers in the next edition of Adiposity
- 101.
