Small Changes Theory

"Small changes" theory may fail to take body's adaptive mechanism into account.
The New York Times (3/1, Parker-Pope) "Well" blog reported that, according to a "recent commentary in The Journal of the American Medical Association," the theory that "cutting out or burning just 100 extra calories a day," known as the "small changes" theory, may fail "to take the body's adaptive mechanisms into account." The JAMA commentary explained that "bodies don't gain or lose weight indefinitely," because "a cascade of biological changes kicks in to help the body maintain a new weight." Unfortunately, the human "body is more resistant to weight loss than weight gain."
