You can lower your cholesterol through a combination of dietary changes, regular exercise, and lifestyle adjustments. For most people without existing heart disease, the goal is to get LDL (the “bad” cholesterol) below 100 mg/dL. If your risk of heart disease is high, your doctor may aim for below 70 mg/dL. The good news is that several of the most effective strategies are things you can start today.
Swap Your Fats
The single most impactful dietary change you can make is replacing saturated fat with unsaturated fat. Saturated and unsaturated fats have opposing effects on LDL cholesterol, and simply shifting the balance between them produces measurable results. In a large meta-analysis of clinical trials, people who ate more polyunsaturated fat (from sources like walnuts, flaxseed, and sunflower oil) while cutting saturated fat saw their LDL drop by about 16 mg/dL compared to those eating a higher-saturated-fat diet. The key detail: this benefit came specifically from replacing saturated fat, not just adding unsaturated fat on top of an unchanged diet.
Current dietary guidelines recommend keeping saturated fat below 10% of your daily calories. For someone eating 2,000 calories a day, that means no more than about 22 grams. The biggest sources of saturated fat in most diets are red meat, full-fat dairy, butter, and coconut oil. Replacing these with olive oil, avocados, nuts, and fatty fish shifts your fat ratio in the right direction. You don’t need to go fat-free. You need to change which fats dominate your plate.
Eat More Soluble Fiber
Soluble fiber acts like a sponge in your digestive system, binding to cholesterol and pulling it out of your body before it reaches your bloodstream. Aim for 5 to 10 grams of soluble fiber per day to see a meaningful decrease in LDL. That’s not as hard as it sounds: a cup of cooked oatmeal has about 2 grams, a medium apple has roughly 1 gram, and a half-cup of cooked black beans delivers around 2 grams.
Other good sources include barley, lentils, Brussels sprouts, pears, and flaxseed. If your current diet is low in fiber, increase gradually over a couple of weeks to avoid bloating and digestive discomfort. Drinking plenty of water helps too.
Add Plant Sterols to Your Diet
Plant sterols (sometimes called phytosterols) are naturally occurring compounds found in small amounts in vegetables, nuts, and grains. Their cell structure resembles cholesterol closely enough that your digestive system absorbs them instead, leaving the actual cholesterol to be excreted as waste. Eating 2 grams of plant sterols daily lowers LDL by 8% to 10%, which is a significant drop from diet alone.
The challenge is that you’d need to eat enormous quantities of whole foods to reach 2 grams naturally. That’s why many people use fortified products: certain margarines, orange juices, and yogurt drinks are enriched with plant sterols. The FDA allows foods with at least 0.65 grams per serving to carry a heart-health claim. Two servings a day with meals gets you to about 1.3 grams, though the recommended target for cardiovascular protection is the full 2 grams.
Exercise Consistently
Regular physical activity raises HDL (the “good” cholesterol that helps clear LDL from your arteries) and can lower LDL directly. A study published in the Journal of the American Heart Association tracked the effects of a 12-week moderate-intensity exercise program and found that HDL increased by 6.6% while LDL dropped by 7.2%. Higher-intensity exercise pushed HDL gains even further, to about 8.2%.
You don’t need a military training schedule to benefit, but you do need consistency. The participants in that study were exercising roughly 9 hours per week at moderate intensity, which included activities like brisk walking, jogging, and calisthenics. For most people, a realistic starting point is 150 minutes per week of moderate activity (brisk walking, cycling, swimming) plus some resistance training. The cholesterol benefits build over weeks, not days, so sticking with it matters more than intensity.
Be Strategic About Omega-3s
Omega-3 fatty acids from fish oil are well known for lowering triglycerides, another type of blood fat linked to heart disease. At a dose of 2 grams per day of EPA and DHA combined, triglycerides drop by an average of about 43 mg/dL. At 3 grams per day, the reduction reaches nearly 69 mg/dL.
There’s an important nuance, though. Omega-3 supplements can actually raise LDL cholesterol slightly, particularly at doses above 2 grams per day and especially when the supplement is high in DHA rather than EPA. The increase is modest (around 3 mg/dL at the peak), but it’s worth knowing if your primary goal is lowering LDL rather than triglycerides. Eating fatty fish like salmon, mackerel, or sardines two to three times per week gives you omega-3s at a dose that supports heart health without the LDL trade-off that high-dose supplements can bring.
Lose Weight if You Carry Extra
Excess body weight, particularly around the midsection, raises LDL and triglycerides while suppressing HDL. Even a modest weight loss of 5% to 10% of body weight improves all three numbers. For someone who weighs 200 pounds, that’s 10 to 20 pounds. The effect compounds with the dietary changes above: if you’re losing weight by replacing processed foods with fiber-rich whole foods and healthier fats, you’re hitting cholesterol from multiple angles at once.
Limit Alcohol and Quit Smoking
Smoking damages blood vessel walls in ways that make it easier for LDL to accumulate as plaque. Quitting removes that ongoing damage and allows your cardiovascular system to begin repairing itself, though the direct effect on cholesterol numbers is less dramatic than dietary changes. The bigger benefit of quitting is reducing your overall risk of heart disease, which is what high cholesterol threatens in the first place.
Alcohol in moderate amounts (one drink per day for women, two for men) has a small positive association with HDL levels in some studies, but the risks of higher intake, including raised triglycerides and liver damage, outweigh any cholesterol benefit. If you don’t drink, there’s no reason to start for heart health.
When Lifestyle Changes Aren’t Enough
For some people, diet and exercise won’t bring LDL down to target on their own. Genetics play a large role in cholesterol production. If your LDL is 190 mg/dL or higher, or if you already have heart disease, medication is typically part of the plan. The 2026 guidelines from the American Heart Association and American College of Cardiology set aggressive targets for people with existing cardiovascular disease: LDL below 70 mg/dL for most, and below 55 mg/dL for those at very high risk.
Even when medication is necessary, lifestyle changes still matter. They reduce the dose you may need and address risk factors that cholesterol drugs don’t touch, like blood pressure, blood sugar, and inflammation. Think of medication and lifestyle as complementary tools rather than alternatives.
