Lowering cholesterol and triglycerides comes down to a handful of changes that work on both numbers simultaneously: shifting what you eat, moving more, and cutting back on sugar and alcohol. Most people with borderline or moderately high levels can make real progress without medication, though very high triglycerides (500 mg/dL and above) typically need medical treatment to prevent serious complications like pancreatitis.
Know Your Starting Numbers
Triglyceride levels fall into four categories: normal is below 150 mg/dL, borderline high is 150 to 199, high is 200 to 499, and very high is 500 and above. For cholesterol, the focus is usually on LDL (the type that builds up in artery walls) and HDL (the type that helps clear it). Your strategy depends on where you fall. Someone with borderline triglycerides and slightly elevated LDL has a different path than someone with very high triglycerides, which signals a more urgent problem requiring close medical supervision.
Swap Your Fats Instead of Avoiding Them
Dietary fat isn’t the enemy, but the type matters enormously. The Dietary Guidelines for Americans recommend keeping saturated fat below 10% of daily calories. On a 2,000-calorie diet, that’s roughly 20 grams, which is easy to exceed with a few servings of cheese, butter, or fatty cuts of meat.
The goal isn’t just eating less saturated fat. It’s replacing it with unsaturated fats that actively improve your lipid profile. The best sources include salmon, trout, herring, tuna, and mackerel (which also deliver omega-3s that target triglycerides specifically), along with walnuts, almonds, pumpkin seeds, flax seeds, avocados, and oils like olive, canola, and sunflower. Think of it as a trade: butter for olive oil on bread, red meat for grilled salmon a couple nights a week, cheese snacks for a handful of almonds.
Add Soluble Fiber
Soluble fiber works like a sponge in your digestive tract, binding to cholesterol and pulling it out of your body before it reaches your bloodstream. The Mayo Clinic notes that 5 to 10 grams of soluble fiber a day is enough to lower LDL cholesterol. That’s a realistic target: a bowl of oatmeal has about 2 grams, a medium apple adds another gram, and half a cup of black beans contributes around 3 grams.
Good daily sources include oats, barley, lentils, beans, citrus fruits, and Brussels sprouts. If your current diet is low in fiber, increase gradually over a couple weeks to avoid bloating.
Cut Added Sugar and Refined Carbs
This is the single most impactful change for triglycerides specifically. When you eat more sugar than your body needs for energy, your liver converts the excess into triglycerides and packages them into particles that circulate in your blood. Diets where added sugars make up more than 20% of calories consistently produce elevated fasting triglycerides.
The American Heart Association recommends a daily ceiling of about 100 calories from added sugar for women (roughly 6 teaspoons) and 150 calories for men (about 9 teaspoons). A single can of regular soda contains around 10 teaspoons, which blows past both limits. Sweetened coffee drinks, fruit juice, candy, baked goods, and flavored yogurts are common culprits. White bread, white rice, and other refined carbohydrates behave similarly in your body, converting quickly to sugar and driving triglyceride production.
Replacing sugary drinks with water, swapping white rice for brown, and choosing whole fruit over juice can produce noticeable drops in triglycerides within weeks.
Rethink Alcohol
Alcohol hits triglycerides through two mechanisms. It stimulates your liver to produce more triglycerides directly, and it suppresses the enzyme (lipoprotein lipase) that normally breaks down triglyceride-rich particles in your blood. The result is a double hit: more triglycerides produced, fewer cleared. Even acute alcohol intake can spike levels dramatically in people who are already prone to high triglycerides.
If your triglycerides are elevated, cutting back on alcohol is one of the fastest ways to see improvement. For some people, especially those with levels above 500 mg/dL, eliminating alcohol entirely may be necessary to avoid dangerous complications.
Exercise Regularly, Not Necessarily Intensely
Physical activity lowers triglycerides and raises HDL cholesterol, and the good news is that moderate intensity works well. You don’t need to run sprints or crush yourself in the gym. Walking briskly, cycling, swimming, or any sustained movement at a pace where you can still hold a conversation makes a meaningful difference.
Consistency matters more than intensity. Exercising at least every other day is key to keeping triglycerides low, because each session helps clear triglyceride-rich particles from your bloodstream in the hours that follow. A 30- to 45-minute moderate workout timed around a meal is especially effective at clearing the post-meal triglyceride surge. Higher volumes of moderate activity also produce the best improvements in HDL cholesterol, the protective type that helps remove LDL from artery walls.
Aim for at least 150 minutes of moderate activity per week, spread across most days rather than crammed into one or two sessions.
Consider Plant Sterols
Plant sterols (also called phytosterols) are natural compounds found in small amounts in vegetable oils, nuts, seeds, and whole grains. They work by blocking cholesterol absorption in your gut. Consuming 2 grams per day lowers LDL cholesterol by roughly 8% to 10%, according to Cleveland Clinic data. The National Cholesterol Education Program recommends this 2-gram daily target for cardiovascular protection.
You can reach it through fortified foods like certain margarines, orange juices, and yogurts that are specifically labeled with their phytosterol content. Look for products providing at least 0.65 grams per serving and have two servings a day with meals. Plant sterols work independently of other dietary changes, so they stack on top of the benefits you get from fiber, healthy fats, and sugar reduction.
When Omega-3s Help With Triglycerides
Omega-3 fatty acids from fish are beneficial at dietary levels, but they become a targeted triglyceride treatment at much higher, prescription doses. The American Heart Association recognizes that 4 grams per day of prescription-strength omega-3s lower triglycerides significantly, whether used alone or alongside other medications. That’s far more than you’d get from eating fish a few times a week or taking a standard over-the-counter fish oil capsule.
Over-the-counter fish oil supplements typically contain 300 to 500 mg of combined omega-3s per capsule. Reaching the therapeutic 4-gram dose would require taking a large number of capsules daily, which isn’t recommended without medical guidance because of potential side effects including bleeding risk. If your triglycerides are stubbornly high despite lifestyle changes, prescription omega-3 formulations are worth discussing with your doctor.
Where Medication Fits In
Lifestyle changes are the first line of treatment, but they have limits. For cholesterol, statins are typically considered when LDL remains high despite diet and exercise, particularly if you have other risk factors like diabetes, high blood pressure, or a family history of early heart disease. For triglycerides, medication becomes more urgent when levels reach 500 mg/dL or above, because the risk of acute pancreatitis rises at that threshold. Fibrates are sometimes added alongside a statin in that scenario, though the combination requires careful monitoring.
The practical reality for most people is that a combination of approaches works best. Cutting sugar, improving your fat sources, adding fiber, exercising consistently, and moderating alcohol don’t produce results as dramatic as medication in isolation, but together they create compounding effects that lower both cholesterol and triglycerides while improving your overall cardiovascular health in ways a pill alone cannot.
