The Claim
Carriers of rare, function-disrupting myostatin gene variants exhibit significantly lower body fat percentage and reduced total adipose tissue volume, as measured by whole-body MRI and bioimpedance in a cohort of over 77,000 individuals.
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.
People with rare mutations in the myostatin gene have lower body fat percentage and less total fat tissue, as measured by MRI and bioimpedance in a study of more than 77,000 people.
See the scientific wording
Carriers of rare, function-disrupting myostatin gene variants have significantly lower body fat percentage and reduced total adipose tissue volume, as measured by whole-body MRI and bioimpedance in over 77,000 individuals, suggesting a reciprocal relationship between muscle gain and fat loss.
When the myostatin protein is disrupted, muscles grow larger because their growth signals are no longer blocked. Larger muscles require more energy, so the body burns more fat to fuel them, leading to less fat storage overall.
What the research says
1 studyPeople born with a rare gene change that limits myostatin end up with more muscle and less fat, and this study proved it by scanning over 77,000 people’s bodies. So yes, less myostatin = more muscle and less fat, together.
