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 .
Lifestyle intervention favorably affects weight loss and maintenance following obesity surgery.
The present study was design ed to evaluate the 3 year effects of a lifestyle intervention on weight loss and maintenance , dietary , and physical activity habits and eating behavior of patients following vertical b and ed gastroplasty ( VBG ) . Thirty severely obese female volunteers were included in the study and they were r and omly assigned to one of two intervention groups : usual care ( UC ) or lifestyle intervention ( LS ) group . Patients were followed for 3 years postoperatively . Outcome measures included weight loss , dietary habits , physical activity level ( PAL ) , and eating behavior changes . Weight was significantly lower in the LS group after 12 months ( 84.4 + /- 3.9 kg vs. 98.4 + /- 4.4 kg , P < 0.05 ) , 24 months ( 83.0 + /- 3.3 vs. 101.9 + /- 5.3 kg , P < 0.05 ) , and 36 months following surgery ( 84.2 + /- 3.3 vs. 102.5 + /- 3.5 kg , P < 0.05 ) . Repeated measures ANOVA revealed significant differences between the two groups overall and at specific time points for the PAL and TV viewing . With regard to eating behavior , the LS group scored significantly better in total Dutch Eating Behavior Question naire ( DEBQ ) , Restraint Eating and External Eating scales at all postoperative time points . Similarly , significant differences were found between the two groups in dietary intake . These findings outline the importance of lifestyle intervention on weight loss and maintenance following bariatric surgery . The favorable effects of lifestyle intervention may be through adoption of healthier eating behaviors and increased physical activity
