简要总结
Studies in overweight and obese subjects show a decline in resting metabolic rate (RMR) even after moderate caloric restriction. Yet the onset and course of such a metabolic adaption is still unclear. Lower resting metabolic rates were also reported after gastric banding bariatric surgery but have not yet been investigated in subjects after gastric bypass. The purpose of this study is to investigate the consequences on resting metabolic rate in subjects with obesity after moderate caloric restriction or gastric bypass.

研究组 & 干预措施
Gastric bypass
Subjects with planned gastric bypass surgery are followed-up in regard of resting metabolic rate.
干预措施: Gastric bypass (Procedure)
Caloric restriction
Caloric restriction calculated by an online weight management program (based on subject's starting weight, start BMI, age, target weight and time span). Subjects are followed-up in regard to resting metabolic rate.
干预措施: Caloric restriction (Behavioral)
