Which action helps reduce LDL cholesterol levels?

• A. Sedentary Behavior
• B. Smoking
• C. High Fat Intake
• D. Exercise

Answer: (D)

Regular exercise improves your lipid profile by lowering LDL cholesterol and raising HDL. When you be active, your body uses fats for fuel, which helps reduce the amount of LDL circulating in the blood. It also boosts liver enzyme activity and receptor function that clear LDL from the bloodstream, and it supports healthier body weight and better insulin sensitivity. These shifts collectively make LDL levels lower. The other choices tend to worsen cholesterol balance—being inactive, smoking, and eating a high-fat diet are associated with higher LDL—so the action that lowers LDL is engaging in regular physical activity.
