In plain English

In adults with overweight, following a ketogenic diet for three months results in a 5.7% increase in HDL cholesterol and no significant change in LDL cholesterol, triglycerides, or the apolipoprotein B/A1 ratio.

See the scientific wording

A three-month ketogenic diet in adults with overweight is associated with a 5.7% increase in HDL cholesterol and no significant change in LDL cholesterol, triglycerides, or apolipoprotein B/A1 ratio, suggesting a neutral or potentially beneficial effect on lipid profiles.

Why this might work

When carbs are drastically reduced, the body stops producing insulin, which tells the liver to stop making cholesterol and start burning fat for fuel. This fat burning produces ketones and signals the liver to make more HDL particles, which carry cholesterol out of the blood and into the liver for disposal, raising HDL levels without changing other fats.

    This study found that after three months of eating a low-carb, high-fat diet, overweight people had 5.7% more 'good' cholesterol and no harmful changes in other fats in their blood — just like the claim says.
