Reducing cholesterol comes down to a combination of dietary changes, regular exercise, and in some cases medication. The most impactful single change for many people is cutting saturated fat to less than 6% of daily calories, which the American Heart Association recommends as the target for managing cholesterol. But most people get the best results by stacking several strategies together.
Know Your Target Numbers
Updated guidelines from 2026 set clearer targets depending on your cardiovascular risk. For people without heart disease, optimal LDL cholesterol is below 100 mg/dL. If you have intermediate risk factors like high blood pressure, diabetes, or a strong family history, the goal drops to below 70 mg/dL. People with the highest risk, including those who’ve already had a heart attack or stroke, should aim for below 55 mg/dL.
These thresholds matter because they shape how aggressively you and your doctor approach treatment. Someone at 115 mg/dL with no other risk factors might do well with diet and exercise alone. Someone at 115 mg/dL with diabetes will likely need medication on top of lifestyle changes.
Cut Saturated Fat and Replace It
Saturated fat is the single biggest dietary driver of LDL cholesterol. It’s concentrated in red meat, full-fat dairy, butter, cheese, and coconut oil. The American Heart Association recommends keeping saturated fat below 6% of your total daily calories. For someone eating 2,000 calories a day, that’s roughly 13 grams, or about the amount in two tablespoons of butter and a slice of cheddar.
What you replace it with matters just as much as what you cut. Swapping saturated fat for unsaturated fats (olive oil, avocados, nuts, fatty fish) lowers LDL. Swapping it for refined carbohydrates like white bread and sugary snacks does not. The goal isn’t a low-fat diet. It’s shifting the type of fat you eat.
Add More Soluble Fiber
Soluble fiber works by binding to cholesterol in your digestive system and pulling it out of the body before it reaches your bloodstream. Five to ten grams of soluble fiber a day is enough to measurably decrease LDL cholesterol. Most people get far less than that.
Good sources include oats, barley, beans, lentils, apples, citrus fruits, and Brussels sprouts. A bowl of oatmeal gives you about 2 grams. A cup of cooked black beans adds another 5 to 6 grams. You don’t need a supplement. A few targeted food swaps across the day can get you there.
Plant Sterols and Stanols
These naturally occurring compounds, found in small amounts in grains, vegetables, and nuts, block cholesterol absorption in the gut. At supplemental doses of 2 to 3 grams per day, they can lower LDL by 7.5% to 12%. You’ll find them added to certain margarines, orange juices, and yogurt drinks, or as standalone supplements. Taking more than 3 grams daily doesn’t provide additional benefit.
Plant sterols work well alongside dietary changes and can be a useful tool if you’re trying to avoid medication or want to push your numbers lower before your next blood test.
Exercise Consistently
Regular physical activity primarily raises HDL (the protective cholesterol) and can modestly lower LDL. In one study, a 12-week moderate-intensity exercise program increased HDL by about 6.6% and decreased LDL by 7.2%. Higher-intensity training pushed HDL up even further, by about 8.2%, though the additional LDL reduction was less consistent.
You don’t need to train like the participants in that study, who averaged over 9 hours of activity per week. Current general guidelines suggest at least 150 minutes of moderate aerobic exercise weekly, things like brisk walking, cycling, or swimming. Adding resistance training two days a week provides additional cardiovascular benefit. The key is consistency over intensity. A 30-minute walk five days a week will do more for your cholesterol than occasional intense workouts.
Quit Smoking
Smoking suppresses HDL cholesterol, and quitting reverses this surprisingly fast. HDL levels begin recovering in as little as 17 days after stopping. By 30 days, one study found HDL had increased by about 5.7 mg/dL. By 60 days, ex-smokers gained another 6.8 mg/dL, bringing their levels close to those of people who never smoked. The catch: people who resumed smoking saw their HDL drop right back to pre-quit levels, confirming that the benefit only holds if cessation sticks.
Omega-3 Fats and Triglycerides
Omega-3 fatty acids from fish oil are better known for lowering triglycerides than LDL. At prescription doses of 4 grams per day, they reduce triglycerides by 30% or more. If you have high triglycerides alongside high LDL, bringing triglycerides down can improve your overall lipid profile and reduce cardiovascular risk.
One nuance worth knowing: combined EPA and DHA supplements can sometimes raise LDL slightly, particularly when triglyceride reductions are large. This appears to reflect larger LDL particles rather than more of them, which may be less harmful. EPA-only formulations don’t seem to raise LDL at all. For most people eating fatty fish two to three times a week, this isn’t a concern. It becomes relevant mainly at high therapeutic doses.
Alcohol: A Complicated Picture
Moderate alcohol consumption does raise HDL cholesterol, by as much as 18% in controlled studies. But this doesn’t translate into a recommendation to start drinking. The HDL benefit is real, yet alcohol carries its own risks: liver disease, cancer, elevated blood pressure, and for some people, higher triglycerides. If you already drink moderately, the HDL effect is a small silver lining. If you don’t drink, there are better ways to raise HDL.
When Lifestyle Changes Aren’t Enough
For many people, diet and exercise alone won’t bring LDL to target, especially if genetics play a strong role. Statins remain the most widely prescribed cholesterol medication and are grouped by intensity. Low-intensity therapy reduces LDL by less than 30%. Moderate-intensity therapy brings it down 30% to 49%. High-intensity therapy can cut LDL by 50% or more.
Your doctor chooses the intensity based on your starting LDL level, your target, and your overall cardiovascular risk. Someone who needs to go from 160 to below 70 mg/dL is looking at high-intensity therapy. Someone nudging down from 130 to below 100 might start with moderate intensity. Lifestyle changes remain important even on medication because they reduce the dose needed and address risk factors that statins don’t touch, like triglycerides and blood pressure.
Red Yeast Rice: A Natural Alternative?
Red yeast rice contains a compound called monacolin K, which has the same chemical structure as a prescription statin. That’s why it can lower cholesterol, but it’s also why it carries the same potential side effects, including muscle pain and liver strain. The amount of monacolin K varies widely between products because supplements aren’t regulated as tightly as drugs. Some brands contain almost none, while others contain enough to function as an unmonitored statin. If you’re considering red yeast rice, it’s worth knowing that you’re essentially taking a variable dose of a medication without the quality control that comes with a prescription.
Putting It All Together
The most effective approach layers multiple strategies. Cutting saturated fat below 6% of calories, adding 5 to 10 grams of soluble fiber, incorporating 2 to 3 grams of plant sterols, exercising regularly, and quitting smoking if you smoke can collectively lower LDL by a meaningful amount. For some people, that’s enough. For others, particularly those with genetic predisposition or existing heart disease, medication closes the remaining gap. The combination of lifestyle and medication, when needed, gives you the widest margin of protection.
