The Claim
In old male mice, a 4-week treatment with an anti-myostatin antibody increases insulin-stimulated whole-body glucose uptake by 16% through enhanced skeletal muscle glucose uptake without changing hepatic glucose production, indicating a direct relationship between increased muscle mass and improved insulin sensitivity in aging.
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.
In older male mice, a 4-week injection of an anti-myostatin antibody increases glucose uptake by muscles during insulin stimulation by 16%, without affecting the liver's glucose output, showing that greater muscle mass is linked to better insulin sensitivity in aging.
See the scientific wording
In old male mice, a 4-week treatment with an anti-myostatin antibody improved insulin-stimulated whole-body glucose uptake by 16%, primarily through increased skeletal muscle glucose uptake, without altering hepatic glucose production, suggesting a link between increased muscle mass and improved insulin sensitivity in aging.
Blocking a protein that limits muscle growth causes muscles to get bigger, and the larger muscles take up more sugar from the blood when insulin is present, improving the body's ability to control blood sugar.
What the research says
1 studyIn older male mice, a special antibody that blocks a muscle-limiting protein made their muscles bigger and better at soaking up sugar from the blood during insulin stimulation — just like the claim said. Their liver didn’t change, so the improvement came from the muscles.
