Evidence is judged against each part on its own, so a study that tests one part never counts as a verdict on the whole claim.
What the research says
1 study reviewedSupporting (1)
Randomized Controlled TrialHuman2019
The study found that older adults who did resistance training got better at everyday physical tasks, but adding a protein supplement did not help more, and their muscle mass did not increase. So exercise may help, but the claim that nutrition and keeping muscle are key is not fully proven here.

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.
