Combining a reducing diet, physical activity, and behavior change techniques produces superior long-term weight loss in men compared to any single component or control.
For men seeking weight loss, do not rely on exercise alone. The most effective approach combines a calorie-reducing diet with regular physical activity and structured behavior change techniques (like goal setting and self-monitoring). Group-based programs delivered in settings men find comfortable (like sports clubs) can be highly effective if they are tailored to be direct, factual, and flexible.
The most effective interventions combined reducing diets, exercise, and behavior change techniques (mean difference in weight at 1 year compared with no intervention was −4.9 kg, 95% confidence interval −5.9 to −4.0, reported p < .0001).
Why this rating
Based on a systematic review of 14 RCTs, but with noted heterogeneity (I2=97%) and moderate quality/bias risks in individual trials.
