Randomized Controlled TrialHuman2026
The study shows petrelintide helped people lose up to 8.6% of their body weight, not 10.7% as claimed. So the claim is too high.
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.
A synthetic hormone binds to receptors in the brain that signal fullness, makes the stomach empty more slowly, and reduces the release of a hormone that raises blood sugar. This causes people to eat less and absorb fewer calories, leading to loss of body weight.

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.
