Energy balance
The addition of exercise to a dietary intervention preserves lean body mass better than dieting alone, although the primary benefit for weight maintenance is behavioral adherence rather than metabolic preservation.
If you are losing weight, adding exercise helps protect your muscle mass better than dieting alone. While the calorie burn from exercise might seem small, it helps you keep the muscle you have, which supports long-term metabolic health and weight maintenance.
GoodQualifiesHIGH confidence
Subjects in the diet program had significantly greater weight loss and loss of lean body mass than the exercise alone group... In contrast, the exercisers lost a total body mass of 4.0 kg but gained 0.1 kg of lean tissue, thereby reducing total fat mass by 4.1 kg.
Why this rating
Based on specific RCT data (Wood et al.) showing body composition differences.
