The Claim

Periodic fasting reduces LDL cholesterol by 6.80 mg/dL compared to a usual diet in adults with overweight or obesity, and it is the only intermittent fasting method shown to significantly improve this lipid marker.

In plain English

In adults with overweight or obesity, periodic fasting lowers LDL cholesterol by 6.80 mg/dL compared to a usual diet, and among intermittent fasting methods, only periodic fasting has been shown to significantly reduce this lipid marker.

See the scientific wording

Periodic fasting reduces LDL cholesterol by 6.80 mg/dL compared to a usual diet in adults with overweight or obesity, with high-certainty evidence, indicating it is the only intermittent fasting method shown to significantly improve this lipid marker.

Why this might work

When food is not eaten for periods of time, the body runs out of sugar stores and starts burning fat for energy. This burns away fat stored in the body and reduces the liver's production of a fat-carrying particle called VLDL. With less VLDL made, there is less of its breakdown product, LDL, circulating in the blood.

  1. Study: Intermittent Fasting for the Prevention of Cardiovascular Disease Risks: Systematic Review and Network Meta-Analysis

    The study found that eating very few calories two days a week lowered 'bad' cholesterol by exactly 6.80 mg/dL, just like the claim says — and it’s based on strong, reliable data.
