Weight loss of obese men compared with women

Men are believed to lose more weight than women. Factors supporting this belief include men's greater weight at the start of treatment and measurement of weight loss in terms of kilograms lost rather than percent of overweight lost. No sex differences in weight loss 1 year after surgery for obesity were observed when men and women were matched preoperatively by weight or overweight. When the total sample was considered, men weighed significantly more than women preoperatively and lost significantly more kilograms postoperatively.
