As I talked about in my last post, the set-point, starvation-response, and metabolic-adaptation theories have kept changing over the years as their advocates attempt to maintain a viable theory. The Truth? Are there physiological changes associated with energy restriction? Yes. Do they prevent weight loss, or maintenance of weight loss? No.

It’s not uncommon to hear both lay persons and professionals matter-of-factly refer to the “starvation response” (also called metabolic adaptation) and “set-point theory” as if they were accepted facts. The supposition of these theories is that the body reacts to reduced energy intake, or weight loss, by lowering its basal metabolic rate in an attempt to maintain the current weight or return to a higher weight.
These theories however, have not survived sound scientific investigation, and those researchers who are familiar with this area of medical literature have known that for almost 20-years. Three comprehensive reviews of the literature in 1992, 1994, and 1995[i],[ii],[iii] all reached the same conclusions that:
