Higher BMI causally increases the risk of Coronary Heart Disease (CHD) independently of LDL cholesterol levels.

High body weight is a direct cause of heart disease risk, but not through the traditional LDL cholesterol pathway. This means that standard lipid-lowering strategies might not fully address the risk in obese individuals unless metabolic health (sugar and triglycerides) is also improved.

We show that higher BMI causes greater CHD risk... our results suggest that BMI is not causally related to LDL-C
