Why Dieters Tend to Regain Weight
from the Los Angeles Times (Registration Required)
As if Americans needed any reminder that weight loss is hard and maintaining weight loss even harder, a study has found that for at least a year, subjects who shed weight on a low-calorie diet were hungrier than when they started and had higher levels of hormones that tell the body to eat more, conserve energy and store away fuel as fat.
The report, published Wednesday in the New England Journal of Medicine, helps explain why roughly 4 in 5 dieters wind up gaining back lost pounds within a year or two of losing them--and, sometimes, pack on a few extra pounds for good measure.
It is a close look at the disheartening pattern: In the wake of weight loss, "multiple compensatory mechanisms" spring to life, the study illustrates, and work together to ensure that weight loss is reversed quickly and efficiently.
