How to Lower LDL Cholesterol: What Works

Start with food: less saturated fat, more soluble fiber, plant sterols and nuts. Diet usually lowers LDL by about 10 to 15%, exercise and weight loss add a little, and medicine closes a bigger gap.

How much can food changes lower LDL?

For most people, diet changes lower LDL cholesterol (LDL-C) by about 10 to 15%. A serious, combined diet like the Portfolio diet can reach about 25 to 30% in people who follow it closely. Responses vary a lot, so treat these as averages.

Saturated fat raises LDL more than any other part of the diet. In a meta-analysis of 60 controlled feeding trials, replacing it with unsaturated fats improved the cholesterol profile, while replacing it with carbohydrates did not. Olive oil, canola oil, nuts, seeds, avocado and fish help most.

What foods lower LDL naturally?

These have the best evidence:

  • Viscous fiber from oats, barley, beans, lentils, okra, eggplant and psyllium. In a 2018 meta-analysis of 28 trials, about 10 grams of psyllium a day lowered LDL-C by about 13 mg/dL.
  • Plant sterols or stanols, about 2 grams a day, which lower LDL by 8 to 10% and add to a statin. Look for fortified spreads, yogurts and supplements.
  • Nuts, soy foods, and unsaturated fats used in place of butter, fatty meat and full-fat dairy.

How well does the Portfolio diet work?

The Portfolio diet combines plant sterols, soy protein, viscous fiber and nuts on top of a low saturated fat diet. In a tightly controlled one-month study where people received all their food, LDL fell 28.6%, close to the 30.9% seen with a starter dose of lovastatin in the same study.

At home the numbers shrink. When 351 people were coached to follow it for six months, LDL-C fell about 13 to 14% (around 25 mg/dL), versus 3% on a standard low saturated fat diet. People who followed it more closely got bigger drops.

Does exercise or weight loss lower LDL?

Both help LDL a little and help triglycerides more. A 2025 meta-analysis of exercise trials found an average LDL-C drop of about 7 mg/dL. Exercise also helps your heart, blood pressure and blood sugar.

In a meta-analysis of 70 weight-loss studies, LDL and triglycerides both fell as weight came off. The LDL change is usually modest, and the bigger payoff tends to be in triglycerides and blood sugar. Neither alone usually brings a high LDL down to goal.

When is medicine needed to lower LDL, and how fast does it work?

If your LDL sits more than about 15 to 20% above your goal, or your risk is high, medicine usually gets you there faster and more surely. Diet and exercise still add to what the medicine does.

A moderate-intensity statin typically lowers LDL by 30 to 49%, and a high-intensity statin by 50% or more.

Per the atorvastatin label, a response shows within 2 weeks and the maximum effect usually arrives within 4 weeks, so clinicians often recheck at about 4 to 12 weeks.

Median figures from the 2026 guideline summary for add-on medicines: ezetimibe about 25% added to a statin (about 18% alone), bempedoic acid 17 to 18% added to a statin, PCSK9 antibodies (Repatha, Praluent) 45 to 64%, and inclisiran (Leqvio) 48 to 52%.

How low should my LDL be?

Under the 2026 ACC/AHA guideline, most adults in primary prevention aim below 100 mg/dL. People at higher risk (10-year risk of 10% or more, or diabetes with multiple risk factors) aim below 70.

People with established heart disease aim below 70, and below 55 at very high risk. An LDL-C of 190 or higher calls for treatment regardless of other risk factors, and familial hypercholesterolemia is worth asking about.

Your goal depends on your own risk, so ask your clinician to calculate it instead of relying on the normal range on a lab report.

Common questions

▸How can I lower LDL in 2 weeks?

A statin produces most of its LDL drop within about two weeks, with the full effect by about four. In a controlled Portfolio diet study, LDL had dropped substantially by the first two-week check. If your LDL sits far above goal, two weeks of diet alone rarely closes the gap.

▸What foods make LDL go down?

Oats, barley, beans, lentils and psyllium (viscous fiber), nuts (especially almonds), soy foods, foods with added plant sterols, and unsaturated fats like olive oil, canola oil and fish in place of butter, fatty meat and full-fat dairy. Combining several works much better than any single food.

▸What should I avoid eating if LDL is high?

Saturated fat drives LDL most, so cut back on fatty red and processed meats, butter, cheese, cream, coconut and palm oil, and many baked and fried foods. Small amounts are fine. Swapping them for unsaturated fats and fiber-rich plant foods moves the number.

▸Can drinking water lower LDL?

Water doesn't lower LDL by itself. Swapping sugary drinks for water can help with weight and triglycerides, a modest indirect benefit.

▸What is a good LDL level?

It depends on your risk. Under the 2026 ACC/AHA guideline, most adults in primary prevention aim below 100 mg/dL. Higher-risk people aim below 70. People with established heart disease aim below 70, or below 55 at very high risk.

▸What LDL level is alarming?

An LDL of 190 mg/dL or higher is called severe hypercholesterolemia. Guidelines recommend treatment at that level regardless of other risk factors. Ask about familial hypercholesterolemia, an inherited cause that also affects relatives.
