Abstract:	OBJECTIVE: Numerous reports have suggested that cycles of weight loss and regain (i.e., weight cycling) are associated with adverse health consequences, a concern that may lead some obese individuals to forgo weight control efforts. The present study examined whether weight cycling was associated with a reduction in resting energy expenditure (REE) and with increases in both total and upper body fat. METHOD: REE, body composition, and body fat distribution were measured before and after weight loss, and following full weight regain, in 12 women who before treatment had a mean (+/- SEM) age of 38.8 +/- 3.4 years and weight of 98.0 +/- 3.2 kg. RESULTS: At the end of treatment, patients lost 18.9 +/- 2.6 kg which was comprised of significant decreases in body fat and fat-free mass of 15.2 +/- 2.2 and 3.7 +/- 0.8 kg, respectively (both ps < .001). REE also fell during this time from 1,631 +/- 82 to 1,501 +/- 51 kcal/d (p < .03). All of these measures, however, returned to their baseline values when patients regained their lost weight. Body fat distribution was unchanged throughout the study. DISCUSSION: These results do not support claims that weight cycling adversely affects REE, body composition, or body fat distribution.
