How to lower cholesterol?

Diet is the fastest lever. Cut saturated fats (red meat, full-fat dairy, palm oil) and replace them with unsaturated fats (olive oil, avocado, nuts). Add soluble fiber — oats, beans, lentils, apples, and psyllium husk all bind to cholesterol in your gut and help remove it.

Exercise raises HDL ("good" cholesterol) and lowers triglycerides. Aim for 30 minutes of moderate cardio (brisk walking, cycling) at least 5 days per week. Even modest activity helps within weeks.

If lifestyle changes aren't enough after 3–6 months, doctors typically prescribe statins (like atorvastatin). These are highly effective and safe for most people. Quitting smoking also significantly improves HDL levels within weeks. Always consult a licensed medical professional for advice specific to your health situation.

Specific foods have strong clinical backing. Plant sterols reduce LDL by 5–15% at 2 grams daily. Oat beta-glucan from oatmeal lowers LDL by 5–10% at 3 grams per day. Psyllium husk (Metamucil) binds cholesterol in the digestive tract — 10 grams daily reduces LDL by roughly 7%.

LDL particle size matters as much as LDL level. Small dense LDL particles are significantly more atherogenic than large buoyant LDL particles — meaning two people with the same total LDL score can have very different cardiovascular risk. A standard cholesterol panel does not measure this; ask your doctor about an advanced lipoprotein panel if you want the full picture.
