Chu L, et al. - Among adolescents at 12 months post-bariatric surgery, researchers studied changes in resting energy expenditure (REE) and metabolic adaptation. For this investigation, they followed adolescents from the SickKids Team Obesity Management Program who had Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgery. At 12 months, predicted REE was 19% lower, while measured REE was 25% lower, regardless of the type of bariatric surgery. Metabolic adaptation can predispose teenagers to weight regain post-bariatric surgery and requires careful nutritional management and advice.
