Effect of behavioural techniques and delivery mode on effectiveness of weight management: systematic review, meta-analysis and meta-regression.
Bottom Line: I(2) indicated that 93% of the variability in outcome was due to differences in programme effectiveness.There was no evidence that other programme characteristics were associated with programme effectiveness.Programmes that support participants to count calories or include a dietitian may be more effective, but the programme characteristics explaining success are mainly unknown.

Mentions: Pooled results from two studies comparing supervised physical activity sessions with recommended physical activity only did not detect a significant difference in weight change at 12 months (mean difference +1.1 kg, 95% CI −2.7 to +4.8), although statistical heterogeneity was high (I2 = 68%) (Fig. 3). There were no direct comparisons based on whether or not the physical activity programme required special resources to enact.
