I’ve been reading around and I’ve come across a lot of questions concerning the Atkins diet and how it differs from other low-carb diets. I wanted to address these questions with some of my own findings that I’ve gathered over the past 40 years.
Dr. Atkins’s arguments are that calories don’t count and that there’s a “metabolic advantage” to consuming a low-carbohydrate diet, leading to the wasting of energy (fat calories) through the urine and feces.
Atkins is never able to support his argument that calories don’t count by citing actual scientific studies showing that the unrestricted intake of carbohydraterestricted food is compatible with weight loss, rather than gain. All of the studies he discusses used a protocol that restricted calories making it impossible to test his claim. And the only study in which calories weren’t restricted, Dr. John Yudkin’s study, easily refuted Atkins’s claim.
Dr. John Yudkin was the only scientist ever to test directly the whole matter of unrestricted food intake. His 1960 paper pre-dated Atkins’s publications by 12 years and concluded that a low-carbohydrate diet automatically reduced food intake and that calories do count.
Without any scientific study to support his claim, Atkins is forced to support his argument by using the unscientific approach of discussing clients who, he claims, became fat on low-calorie diets. Placed on his version of the low-carbohydrate diet, with its purported higher calorie content, they lost weight, according to him.
This is the “fact” that he uses to justify his invalidation of the calorie theory. Atkins’s argument falls apart when we put-it-to-the-numbers, using standard nutritional calculations for metabolic rates. What becomes clear, from such calculations, is that his clients must have mis-reported their food intake. This fact is as undeniable as the fact that calories do count, as reliable as the rising and setting of the sun and the freezing of
water at 32 degrees.
