title: Feasibility and Impact of a Combined Supervised Exercise and Nutritional-Behavioral Intervention following Bariatric Surgery: A Pilot Study.
abstract: BACKGROUND
  Lifestyle intervention programs after bariatric surgery have been suggested to maximise health outcomes. This pilot study aimed to investigate the feasibility and impact of an 8-week combined supervised exercise with nutritional-behavioral intervention following Roux-en-Y gastric bypass and sleeve gastrectomy.
  
  
  METHODS
  Eight female patients (44 ± 8 years old, BMI = 38.5 ± 7.2 kg m(-2)) completed the program. Before and after intervention, anthropometric measures, six-minute walk test (6MWT), physical activity level, eating behavior, and quality of life (QoL) were assessed. Percentage weight loss (%WL) outcomes were compared with a historical matched control group.
  
  
  RESULTS
  The program significantly improved functional capacity (mean increment in 6MWT was 127 ± 107 meters, p = 0.043), increased strenuous intensity exercise (44 ± 49 min/week, p = 0.043), increased consumption of fruits and vegetables (p = 0.034), reduced consumption of ready meals (p = 0.034), and improved "Change in Health" in QoL domain (p = 0.039). The intervention group exhibited greater %WL in the 3-12-month postsurgery period compared to historical controls, 12.2 ± 7.5% versus 5.1 ± 5.4%, respectively (p = 0.027).
  
  
  CONCLUSIONS
  Lifestyle intervention program following bariatric surgery is feasible and resulted in several beneficial outcomes. A large randomised control trial is now warranted.
