2 studies reviewedSupporting (1)
Time-Restricted Eating in Adults With Metabolic Syndrome
Randomized Controlled TrialHuman2024
The study found that eating all food within an 8-10 hour window slightly lowered blood sugar over 3 months compared to regular diet advice, matching the claim.

Randomized Controlled TrialHuman2025
The study found that eating all food within an 8-hour window did not lower blood sugar any more than just following a healthy Mediterranean diet for 12 weeks.
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.
