Hormones don't directly change your body; they switch on parts of your DNA instead.
See the scientific wording
Hormones act as activators of specific DNA segments rather than directly creating changes in the body.

Parts of this claim
Hormones act as activators of specific DNA segments.
Not testedNo studiesHormones do not directly create changes in the body.
Not testedNo studiesDNA ultimately determines phenotypic outcomes.
Not testedNo studies
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
2 studies reviewedSupporting (2)
Cross-Sectional StudyAnimal2025
This study found that a hormone (GnRH) works by turning on a specific gene through a DNA switch. That supports the idea that hormones switch on parts of your DNA, but the study only looked at one hormone and one gene.
Cross-Sectional StudyIn vitro1995
This study shows estrogen works by flipping switches on DNA through its receptor, not by directly changing the body. That fits the claim, though the study doesn't follow through to actual body changes.

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.
