Skeletal muscle controls how the body removes glucose from the blood and helps maintain normal insulin sensitivity.

See the scientific wording

Skeletal muscle plays a regulatory role in glucose disposal and contributes to the maintenance of insulin sensitivity.

That doesn't mean it's settled — it just means no study has tested the opposite.

Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.

Scores reflect study quality, not just count.

Why this might work

When insulin is present, it triggers muscle cells to move glucose transporters to their surface, allowing sugar from the blood to enter the muscle. If this process is blocked, sugar stays in the blood and insulin stops working properly. Muscle cells also need to break down the sugar they take in, and if they can't do that efficiently, insulin resistance develops. Fat buildup in muscle from excess fat in the blood can block insulin signaling, making it harder for glucose transporters to reach the surface.

How Fit Body Science checks a claim

  1. 1

    We isolate the claim

    Health advice from videos, articles and studies is broken down into single, testable claims.

  2. 2

    We find the research

    Each claim is matched against peer-reviewed studies, with every source cited by DOI.

  3. 3

    We grade the evidence

    Studies are scored on methodology, statistical rigor, transparency and publication quality.
