Adherence
Male-only weight loss interventions are effective at producing clinically significant weight loss (mean reduction >5%) when they include specific structural components: younger participant age, high contact frequency (>2.7 times/month), face-to-face group delivery, and prescribed energy restriction.
If you are a man looking to lose weight, look for programs specifically designed for men. The most effective ones involve meeting with a group in person more than twice a month and include a clear plan for reducing your calorie intake. These structural elements seem to help men stick with the program and lose a significant amount of weight.
Characteristics common to effectiveness were younger sample (mean age <42.8 years), increased frequency of contact (>2.7 contacts/month), group face-to-face contact and inclusion of a prescribed energy restriction.
Why this rating
The review notes that study quality was 'mostly poor' (median 3/10) and calls for more high-quality studies, though the meta-analysis showed a significant pooled effect.
