|Lean mass (lbs)||-2.4||2.0||1|
The group that exercised and dieted lost more fat than the groups that either dieted or exercised alone. The group that exercised gained the most muscle mass and interestingly, lost more body fat as compared to the diet group, although weight loss was marginally less. This study also demonstrates that exercise can maintain (and increase) lean mass while dieting.
