When people lose muscle, their body becomes less efficient at removing sugar from the blood. This happens because muscle tissue is a primary site for glucose uptake.

Loss of skeletal muscle mass reduces glucose disposal capacity in humans.

Observational4 moderate-quality studies link this claim to the outcome, but causation is not established.
What the research says
4 studies reviewedSupporting (4)
Cohort StudyHuman
When people stayed in bed for 10 days (which causes muscle loss), their muscles became worse at taking sugar out of the blood, supporting the idea that losing muscle makes it harder for the body to remove sugar.
Bed rest worsens impairments in fat and glucose metabolism in older, overweight adults.
Cohort StudyHuman2014
When older, overweight people stayed in bed for 10 days, their muscles shrank, and their bodies became worse at removing sugar from the blood, showing that losing muscle hurts blood sugar control.
Cohort StudyHuman2012
When people lose muscle from being in bed for a long time, their muscles become worse at using sugar, making it harder to remove sugar from blood.

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.

How Fit Body Science checks a claim
- 1
We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.
