Adherence
Energy restriction combined with behavioral modification and exercise (LED) is more effective for weight loss than low-fat, low-carbohydrate, or Mediterranean diets.
For significant weight loss, combine a moderate calorie deficit (approx. 1000-1200 kcal/day) with behavioral strategies (like self-monitoring) and regular exercise. This structured approach was found to be more effective than following specific diets like Low-Fat or Mediterranean diets alone.
ModerateSupportsMEDIUM confidence
The behavior modification+exercise (LED) versus low-fat diet (LFD) was more effective [P=0.99, MD=-6.60 (-9.07, -4.13)].
Why this rating
Based on 3 RCTs; consistent results within the network.
