The Claim

Ketogenic diets significantly increase low-density lipoprotein (LDL) cholesterol concentrations in adults compared to control diets, with a pooled mean difference of 0.35 mmol/L (95% CI: 0.20-0.50) based on pooled data from 27 randomized controlled trials.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Eating a ketogenic diet (very low carb, high fat) makes the 'bad' cholesterol called LDL go up in adults by about 0.35 mmol/L on average, according to 27 research studies.

What the research says

1 study

  1. Study: Impact of the ketogenic diet as a dietary approach on cardiovascular disease risk factors: a meta-analysis of randomized clinical trials.

    This study looked at 27 different experiments testing ketogenic diets and found they raised LDL cholesterol by exactly 0.35 mmol/L on average - the same number mentioned in the claim. The study confirms the claim is accurate.
