Lowering high cholesterol comes down to a combination of dietary changes, regular physical activity, and in some cases medication. How aggressively you need to act depends on your overall cardiovascular risk, but the lifestyle strategies work for nearly everyone. Current guidelines use a 10-year risk score to determine treatment goals: people at moderate risk generally aim for LDL below 100 mg/dL, while those at high risk (10% or greater chance of a cardiovascular event in the next decade) target LDL below 70 mg/dL.
Cut Back on Saturated Fat
Saturated fat is the single biggest dietary driver of LDL (“bad”) cholesterol. It raises LDL by slowing your liver’s ability to clear it from the bloodstream. The current recommendation for people working to lower cholesterol is to keep saturated fat to 5% to 6% of daily calories. On a 2,000-calorie diet, that translates to roughly 11 to 13 grams per day.
To put that in perspective, a single fast-food cheeseburger can contain 10 to 15 grams of saturated fat, and a tablespoon of butter has about 7 grams. The biggest sources in most people’s diets are full-fat dairy (cheese, cream, butter), red meat, and baked goods made with palm or coconut oil. Swapping these for unsaturated fats, like olive oil, nuts, avocado, and fatty fish, lowers LDL without requiring you to eat less fat overall. You’re replacing one type with another.
Trans fats are even worse than saturated fat for cholesterol levels, but they’ve been largely removed from the food supply. Still, check labels on packaged baked goods and fried foods for “partially hydrogenated oil,” which signals trans fat may be present even when the label reads 0 grams (manufacturers can round down from 0.5 grams per serving).
Add More Soluble Fiber
Soluble fiber works like a sponge in your digestive tract, binding to cholesterol-rich bile acids and pulling them out of your body before they can be reabsorbed. Eating 5 to 10 grams of soluble fiber per day measurably lowers LDL cholesterol. That’s a realistic daily target: a bowl of oatmeal gives you about 2 grams, a cup of cooked black beans about 5 grams, and a medium apple about 1 gram.
Other good sources include barley, lentils, Brussels sprouts, flaxseed, and oranges. If your current diet is low in fiber, increase intake gradually over a couple of weeks and drink plenty of water to avoid bloating.
Consider Plant Sterols
Plant sterols (and their close relatives, stanols) are natural compounds found in small amounts in grains, nuts, and vegetable oils. They compete with cholesterol for absorption in your gut, effectively blocking some of it from entering your bloodstream. Consuming about 2 grams per day reduces LDL cholesterol by roughly 9%. You won’t get that much from food alone, so manufacturers add plant sterols to certain margarines, orange juices, and yogurt drinks. Look for products labeled “with added plant sterols” and check the nutrition panel for the per-serving amount. Two servings a day of a fortified spread typically gets you to the 2-gram target.
Exercise Regularly
Physical activity primarily helps by raising HDL (“good”) cholesterol and improving how your body processes fats. Moderate-intensity exercise, things like brisk walking, cycling, or swimming, can increase HDL by about 7%. Stepping up to vigorous activity pushes that closer to 8% or more. The general target is at least 150 minutes per week of moderate activity, or 75 minutes of vigorous activity, spread across most days.
Exercise has a more modest direct effect on LDL, but it shifts LDL particles toward a larger, less harmful size. It also lowers blood pressure and improves blood sugar control, both of which reduce cardiovascular risk independently of cholesterol numbers. The key is consistency. A few weeks of regular activity won’t change your lipid panel much, but sustained effort over two to three months will.
Quit Smoking
Smoking doesn’t just damage your lungs. It directly impairs how HDL cholesterol functions. HDL’s job is to pull excess cholesterol out of artery walls and transport it back to the liver for disposal, a process called cholesterol efflux. Smoking weakens this function and increases oxidative damage to HDL particles, making them less effective even if your HDL number looks normal on a lab test.
After quitting, HDL’s ability to remove cholesterol from arteries and resist oxidative damage improves significantly, even before the HDL number itself rises on your blood work. This means the functional benefit of quitting starts before you see a change on your next lipid panel. The improvement correlates with how completely you stop: people who successfully quit see the greatest gains, while those who only cut back see smaller changes.
Choose a Heart-Healthy Eating Pattern
Rather than fixating on individual nutrients, adopting an overall dietary pattern tends to produce better long-term results. The Mediterranean diet, which emphasizes vegetables, fruits, whole grains, legumes, fish, nuts, and olive oil while limiting red meat and processed foods, is one of the most studied approaches. Interestingly, a meta-analysis in The American Journal of Medicine found that the Mediterranean diet doesn’t lower LDL dramatically more than a standard low-fat diet (only about 3 mg/dL difference). Its cardiovascular benefit likely comes from improving multiple risk factors at once: inflammation, blood pressure, blood sugar, and triglycerides, not just LDL alone.
The DASH diet, originally designed for blood pressure, also improves cholesterol by emphasizing fruits, vegetables, whole grains, and lean protein while keeping sodium and saturated fat low. Both patterns share a common thread: they naturally reduce saturated fat and increase fiber without requiring you to count every gram.
When Lifestyle Changes Aren’t Enough
For many people, diet and exercise alone can bring cholesterol into a healthy range. But if your LDL stays elevated despite consistent lifestyle changes, or if your starting LDL is 190 mg/dL or higher, medication becomes an important part of the plan. The 2026 ACC/AHA guidelines now recommend considering cholesterol-lowering therapy for anyone with at least a 3% estimated 10-year risk of cardiovascular disease, a lower threshold than previous guidelines used.
For people at intermediate risk (5% to under 10%), statins are typically the first option, with a goal of reducing LDL by at least 50% or getting it below 100 mg/dL. Those at high risk (10% or greater) have a tighter target of LDL below 70 mg/dL. People who already have heart disease and are at very high risk aim for below 55 mg/dL, sometimes requiring additional medications on top of a statin to get there.
If you can’t tolerate statins, or they aren’t enough on their own, other prescription options exist that work through different mechanisms: some block cholesterol absorption in the gut, others help the liver clear LDL more aggressively, and newer injectable options can cut LDL by 50% or more on top of what a statin achieves.
Be Cautious With Supplements
Red yeast rice is the most popular over-the-counter supplement marketed for cholesterol. It contains a compound called monacolin K, which is chemically identical to the active ingredient in a prescription statin. Products with a high amount of monacolin K can lower total cholesterol, but here’s the problem: the amount varies wildly between brands, and there’s no standardized dose. Some products contain almost none, making them ineffective. Others contain enough to cause the same side effects as a prescription statin, including muscle pain and potential liver or kidney issues, without the quality control.
Red yeast rice supplements can also be contaminated with citrinin, a toxin harmful to the kidneys. They interact with grapefruit, alcohol, certain antibiotics, and immune-suppressing drugs. If you’re considering red yeast rice, it’s worth knowing that you’re essentially taking an unregulated, inconsistently dosed version of a medication that’s available in a precisely dosed prescription form.
Omega-3 fish oil supplements, while beneficial for very high triglycerides, have minimal effect on LDL cholesterol specifically. Fiber supplements like psyllium husk can help if you’re struggling to get enough soluble fiber from food, but they work best as a complement to dietary changes, not a replacement.
How Quickly You Can Expect Results
Dietary changes can start lowering LDL within two to three weeks, with the full effect visible after about three months. That’s why most guidelines recommend rechecking your lipid panel 8 to 12 weeks after making changes. Statins work faster, often producing a noticeable LDL drop within 4 to 6 weeks. Exercise-related improvements in HDL and triglycerides also take roughly two to three months of consistent effort to show up on lab work.
The most effective approach combines several strategies at once. Cutting saturated fat, adding soluble fiber and plant sterols, exercising regularly, and maintaining a healthy weight can collectively lower LDL by 20% to 30% in people with mildly to moderately elevated levels. For people who need more than that, medication closes the remaining gap.
