The Claim

In old male mice, a 4-week anti-myostatin antibody treatment reduced intramuscular triglyceride content by approximately 30% without changing hepatic triglyceride levels, indicating a tissue-specific effect on lipid metabolism in skeletal muscle.

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.

How it works
1 study reviewed
In plain English

In older male mice, a 4-week treatment with an anti-myostatin antibody lowered fat levels inside muscle tissue by about 30% but did not change fat levels in the liver.

See the scientific wording

In old male mice, a 4-week anti-myostatin antibody treatment reduced intramuscular triglyceride content by approximately 30% without changing hepatic triglyceride levels, suggesting a tissue-specific effect on lipid metabolism in skeletal muscle.

Why this might work

Blocking myostatin makes muscle fibers grow larger, which increases the muscle's ability to burn fat for energy. As a result, the fat stored inside the muscle decreases, but fat in the liver stays the same because the liver is not affected by this process.

  1. Study: Anti-myostatin antibody increases muscle mass and strength and improves insulin sensitivity in old mice

    In older male mice, a treatment that blocks a protein called myostatin made muscles bigger and stronger, and also cut down the fat inside the muscles by 30%—but didn’t change the fat in the liver. This means the treatment only affected the muscles, not the liver.
