Alternate day fasting with a low-carbohydrate diet significantly reduces LDL cholesterol, systolic blood pressure, and fasting insulin in adults with obesity.

If you have high LDL, high blood pressure, or high fasting insulin, this specific combination of fasting and low-carb eating may help improve these markers. Monitor your levels with your doctor, as individual responses to low-carb diets on cholesterol can vary.

Total cholesterol and low‐density lipoprotein (LDL) cholesterol levels decreased (P < .05) by −6 ± 2% and − 8 ± 3%, respectively, by month 6. Systolic blood pressure was also reduced (P = .03) by −7 ± 3 mm Hg. Fasting insulin decreased (P = .03) by −24 ± 8% by month 6 relative to baseline.
