Evidence that supports the prescription of low-carbohydrate high-fat diets: a narrative review

LCHF diets consistently improve multiple cardiovascular risk factors while lowering body weight.

• Blood total cholesterol and LDL-cholesterol levels vary widely among individuals following LCHF diets.
• LCHF diets are associated with lower blood glucose, insulin, triglycerides, and glycated hemoglobin (HbA) levels.
• This dietary approach reduces small dense LDL particle numbers and blood pressure.
• LCHF diets may increase low HDL-cholesterol concentrations and help reverse non-alcoholic fatty liver disease (NAFLD).
• The effects of LCHF diets may stem from reduced hunger and lower calorie intake.
