The Claim
Nonpharmacologic weight loss interventions, such as lifestyle changes, result in muscle loss exceeding prespecified benchmarks in nearly half of cases.
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 people lose weight through diet and exercise, their muscle mass decreases beyond established thresholds in almost half of cases.
See the scientific wording
Nonpharmacologic weight loss interventions, such as lifestyle changes, also result in muscle loss exceeding prespecified benchmarks in nearly half of cases, suggesting that muscle loss during weight loss is not unique to incretin therapies.
When the body burns more calories than it takes in, it breaks down muscle tissue to release amino acids for energy, even when diet and exercise are used to lose weight.
What the research says
1 studyStudy: Effect of Incretin-Based and Nonpharmacologic Weight Loss on Body Composition : A Systematic Review.
Even when people lose weight by eating better and exercising, almost 4 out of 10 lose more muscle than expected — showing this isn't just a problem with weight-loss drugs, but happens with diet and exercise too.
