"Geissler et al. found that previously obese women who had maintained
their target weights for an average of 2.5 years had a metabolic rate about
15% less and ate significantly less (1298 vs 1945 calories) than lean
controls. Liebel and Hirsch have reported that the reduced metabolic
requirements endure in obese patients who have maintained a reduced body
weight for 4-6 years. Thus, successful weight loss and maintenance is not
accomplished by "normalizing eating patterns" as has been implied in many
treatment programs but rather by sustained caloric restriction.
All diets fall into a few categories but the bottom line
is some kind of calorie restriction.
