Even if your bad cholesterol is low, you can still have a heart attack if other problems like high blood sugar or high blood pressure are still there.
See the scientific wording
Cardiovascular risk persists despite low LDL cholesterol levels if concomitant metabolic syndrome, hypertension, chronic inflammation, or dysglycemia remain unaddressed.

What the research says
3 studies reviewedSupporting (2)
Metabolic syndrome predicts cardiovascular risk and mortality in familial hypercholesterolemia.
Cohort StudyHuman2023
Even if someone has high cholesterol, having other problems like obesity, high blood pressure, or diabetes still makes their heart at much higher risk—this study shows that those extra problems are dangerous on their own, even when cholesterol is being managed.
Narrative ReviewReview2025
Even when bad cholesterol (LDL) is kept low, people with diabetes still have high heart disease risk if other problems like inflammation or high blood sugar aren’t fixed — and this study shows that.

Cohort StudyHuman2024
Even if someone has other health problems like high blood sugar or obesity, this study found that if their 'bad cholesterol' (LDL) is kept low, their heart risk doesn’t go up as much — which is the opposite of what the claim says.
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.
