Using daily point systems to track diet adherence is linked to the development of unhealthy eating patterns.
See the scientific wording
Gamifying individual diet adherence to achieve a daily score is associated with the development of unhealthy dietary habits.
Correlational — new studies may shift this
Observational2 moderate-quality studies link this claim to the outcome, but causation is not established.
What the research says
2 studies reviewedSupporting (2)
Systematic ReviewReview2025
People who use apps that give daily points for eating 'right' tend to show signs of unhealthy obsession with food and exercise — but we don't know yet if the apps cause this or if people already prone to these habits are just more likely to use the apps.
Cross-Sectional StudyHuman2025
People who use apps to track every bite they eat with points or calories were more likely to develop unhealthy eating habits and obsess over their bodies than people who only tracked exercise. This suggests daily diet scoring systems might cause more harm than good.

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.
When a person earns points for eating certain foods, the brain links those foods with a reward, making the person crave them more. Over time, the brain starts treating other foods as 'bad,' which increases stress when those foods are eaten. This stress weakens the brain's ability to make flexible choices, so the person keeps eating only the 'good' foods even when it's unhealthy.

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.
