The Claim
Diet-induced weight loss in adults with overweight or obesity is associated with a reduction in muscle strength, particularly in the lower limbs.
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 adults with overweight or obesity lose weight through dieting, their muscle strength, especially in the legs, decreases.
See the scientific wording
Diet-induced weight loss in adults with overweight or obesity is associated with a reduction in muscle strength, particularly in the lower limbs, despite the known health benefits of weight loss, suggesting that concurrent resistance training may be necessary to preserve strength.
When the body loses weight by eating less, it breaks down muscle tissue for energy, especially in the legs, and the nerves that tell muscles to contract become less active, making the muscles weaker.
What the research says
1 studyLosing weight by eating less can make your legs weaker, especially if you don’t exercise — this study found a clear drop in leg strength after dieting. Adding strength training while dieting can help keep your muscles strong.
