LCHF diets improve cardiovascular risk profiles by lowering triglycerides, increasing HDL cholesterol, and reducing small dense LDL particles, even if total LDL cholesterol increases in some individuals.
Monitor your full lipid panel, not just LDL. If your LDL rises, check your triglycerides and HDL. LCHF diets typically lower triglycerides and raise HDL, and shift LDL particles to a less harmful size, which may indicate improved heart health despite a higher LDL number.
GoodQualifiesHIGH confidence
LCHF diets consistently reduce the proportion of small, dense LDL particles while increasing the number of large, buoyant LDL particles... LCHF-induced decrease in blood TG concentrations indicates a less atherogenic distribution of these LDL particle subfractions.
