The Claim
During moderate energy restriction in overweight, postmenopausal women, the loss of fat-free mass is primarily attributable to a reduction in total body water rather than a reduction in protein–mineral mass, as protein–mineral mass remains unchanged in both sedentary and resistance-trained groups.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When overweight women after menopause eat fewer calories but don’t lose weight too fast, the weight they lose from their muscle and non-fat tissue is mostly just water going out, not actual muscle or minerals—no matter if they exercise or not.
See the scientific wording
Fat-free mass loss during moderate energy restriction in overweight, postmenopausal women is primarily due to loss of total body water, not protein–mineral mass, as protein–mineral mass remained unchanged in both sedentary and resistance-trained groups.
What the research says
1 studyThe study found that when overweight older women lost weight on a diet, any loss of lean body mass was mostly from water, not muscle or minerals — and lifting weights helped them keep even that water. So yes, the claim is right.
