Impact of nutritional‐behavioral and supervised exercise intervention following bariatric surgery: The BARI‐LIFESTYLE randomized controlled trial

Objective The study's aim was to investigate the impact of a 12‐month adjunctive lifestyle intervention on weight loss and health outcomes after bariatric surgery. Methods A total of 153 participants (78.4% females; mean [SD], age 44.2 [10.6] years; BMI 42.4 [5.7] kg/m2) were randomized to inte...

Description
Summary:Objective The study's aim was to investigate the impact of a 12‐month adjunctive lifestyle intervention on weight loss and health outcomes after bariatric surgery. Methods A total of 153 participants (78.4% females; mean [SD], age 44.2 [10.6] years; BMI 42.4 [5.7] kg/m2) were randomized to intervention (n = 79) and control (n = 74). The BARI‐LIFESTYLE program combined 17 nutritional‐behavioral tele‐counseling sessions plus once‐weekly supervised exercise for 12 weeks. The primary outcome was percentage weight loss at 6 months post surgery. Secondary outcomes included body composition, physical activity levels, physical function and strength, health‐related quality of life, depressive symptomatology, and comorbidities. Results Longitudinal analysis of the entire cohort showed significant reductions in body weight, fat mass, fat‐free mass, and bone mineral density at the total hip, femoral neck, and lumbar spine (all p  0.05) and no between‐group differences in secondary outcomes. Conclusions An adjunctive lifestyle program implemented immediately after surgery had no favorable impact upon weight loss and health outcomes.
