Behavioural interventions appear to improve weight loss at 12 months after bariatric surgery .
Background Significant , sustained weight loss through conventional , non-surgical interventions is often unattainable for people with severe obesity ( e.g. BMI ≥40 or ≥35 kg/m2 with co-morbidities ) .
Bariatric surgery is effective in treating severe obesity , but surgery alone without additional behaviour change management may not result in optimum long-term weight loss and maintenance .
This systematic review and meta- analysis of r and omised controlled trials evaluated the effectiveness of lifestyle interventions before and /or after bariatric surgery .
High-volume exercise program in obese bariatric surgery patients: a randomized, controlled trial.
Weight regain is a problem among many bariatric surgery patients . Whether a high-volume exercise program ( HVEP ) , a strategy to limit weight regain , is feasible in these patients is unknown . The feasibility of an HVEP in obese post-bariatric-surgery patients was determined by r and omizing 33 Roux-en-Y gastric bypass ( RYGB ) and gastric b and ing ( GB ) surgery patients with a mean BMI of 41 ± 6 kg/m2 to an HVEP or control group for 12 weeks . The HVEP group was instructed to expend ≥ 2,000 kcal/week in moderate-intensity exercise . All patients were counseled to limit energy intake . Treatment effect was assessed by repeated measures analysis . During the last 4 weeks of the study , 53 % of the HVEP group expended ≥ 2,000 kcal/week and 82 % expended ≥ 1,500 kcal/week . Step count , reported time spent and energy expended during moderate physical activity , maximal oxygen consumption relative to weight , and incremental area under the postpr and ial blood glucose curve were significantly improved over 12 weeks in the HVEP group compared to controls ( group-by-week effect : P = 0.009 - 0.03 ) . Both groups reported significant improvement in some quality -of-life scales . Changes in weight , energy and macronutrient intake , resting energy expenditure ( REE ) , fasting lipids and glucose , and fasting and postpr and ial insulin concentrations were not different between the two groups . HVEP is feasible in about 50 % of the patients and enhances physical fitness and reduces postpr and ial blood glucose in bariatric surgery patients
