High triglycerides respond well to lifestyle changes, often dropping significantly within weeks of targeted adjustments to diet, exercise, and body weight. For most people with mild to moderately elevated levels (150 to 499 mg/dL), these changes alone can bring numbers back into a healthy range. Severe levels above 500 mg/dL typically require medication alongside lifestyle shifts.
Know Your Numbers First
A normal triglyceride level for adults is below 150 mg/dL. Levels between 150 and 199 mg/dL are considered mildly elevated, 200 to 499 mg/dL is moderate, and anything above 500 mg/dL is severe. These distinctions matter because the approach changes at each tier. At mild to moderate levels, the focus is lifestyle. At severe levels, medication becomes important partly because triglycerides above 1,000 mg/dL carry a 10 percent risk of acute pancreatitis, a painful and potentially dangerous inflammation of the pancreas.
Cut Back on Sugar, Especially Fructose
Sugar is one of the biggest dietary drivers of high triglycerides, and fructose is the worst offender. When your liver gets flooded with fructose, it converts the excess directly into fat particles that get shipped into your bloodstream. Animal studies have shown that fructose nearly doubles triglyceride levels compared to glucose, largely because it stimulates the liver to pump out these fat-rich particles at a much higher rate. Fructose also promotes insulin resistance over time, which further ramps up fat production in a compounding cycle.
The practical targets here are sugary drinks, fruit juices, candy, baked goods, and anything sweetened with high-fructose corn syrup. These are the biggest sources of concentrated fructose in most diets. Refined carbohydrates like white bread, white rice, and pasta also raise triglycerides because your body rapidly converts them into simple sugars. Swapping these for whole grains, vegetables, and legumes removes a major trigger.
Prioritize Exercise
Regular physical activity lowers triglycerides through a straightforward mechanism: it helps your body clear fat particles from the bloodstream more efficiently. Research shows that a single session of vigorous exercise can increase the rate at which your body removes triglyceride-rich particles by 25 to 40 percent, and this effect lasts 12 to 24 hours after you stop exercising. That’s why consistency matters more than intensity on any single day.
Aim for at least 150 minutes of moderate aerobic activity per week, the equivalent of a brisk 30-minute walk five days a week. Higher-intensity options like running intervals can be effective in shorter sessions. One well-studied protocol used three sessions per week of 32 minutes of interval running and produced meaningful improvements in how the liver handles fat. The key takeaway is that almost any form of regular cardio helps, whether it’s swimming, cycling, brisk walking, or jogging. Pick what you’ll actually stick with.
Lose Even a Modest Amount of Weight
If you’re carrying extra weight, losing it has an outsized effect on triglycerides. In one study, women with abdominal obesity who lost 10 percent of their body weight saw the rate at which their liver produced triglyceride-rich particles drop by roughly 40 percent. For someone weighing 200 pounds, that’s a 20-pound loss producing a dramatic shift in liver metabolism.
You don’t need to reach an ideal body weight to see benefits. Even a 5 to 7 percent loss, around 10 to 14 pounds for a 200-pound person, tends to produce noticeable improvements in blood work. The weight loss itself matters more than the specific diet used to achieve it, though avoiding the sugars and refined carbs described above gives you a two-for-one benefit.
Choose the Right Fats
Not all dietary fats affect triglycerides the same way. Trans fats, found in some fried foods and processed snacks, are the most harmful. They raise triglycerides while also worsening cholesterol ratios. Saturated fat from red meat, butter, and full-fat dairy is a secondary concern.
Replacing these with polyunsaturated fats, the type found in fatty fish, walnuts, flaxseed, and sunflower oil, offers a modest triglyceride-lowering effect. A meta-analysis in Arteriosclerosis, Thrombosis, and Vascular Biology found that diets high in polyunsaturated fats consistently produced lower triglyceride levels than diets high in either saturated or monounsaturated fats. Monounsaturated fats (olive oil, avocados) are still a healthy swap for saturated fat, but polyunsaturated sources appear to have a slight edge specifically for triglycerides.
Add Omega-3 Fatty Acids
Omega-3 fatty acids from fish oil are one of the most well-documented triglyceride-lowering tools available. The effect is dose-dependent: each additional gram of EPA and DHA per day reduces triglycerides by about 5.9 mg/dL, with stronger effects in people whose levels are higher to begin with. At dietary doses from eating fatty fish (salmon, mackerel, sardines) two to three times per week, you can expect a modest reduction.
For people with significantly elevated triglycerides, the American Heart Association recognizes prescription-strength omega-3s at 4 grams per day as an effective treatment, whether used alone or combined with other medications. Over-the-counter fish oil supplements contain lower concentrations and are less standardized, so they’re harder to dose precisely. If your triglycerides are above 200 mg/dL, talk to your provider about whether a prescription formulation makes sense.
Add Soluble Fiber to Your Diet
Soluble fiber, the type that dissolves in water and forms a gel in your digestive tract, helps regulate how your body absorbs fats and sugars. The National Lipid Association recommends 5 to 10 grams of soluble fiber daily for improving blood lipid levels. That amount can lower total and LDL cholesterol by 5 to 11 points, and its effects on triglycerides come indirectly through better overall fat metabolism and blood sugar control.
Getting to 10 grams per day is achievable by combining several modest sources: a bowl of oatmeal (about 2 grams), a serving of beans or lentils (2 to 3 grams), an apple or pear with the skin on (1 gram), and a handful of flaxseed (1 to 2 grams). Building these into your regular meals adds up quickly without requiring a drastic diet overhaul.
Limit Alcohol
Alcohol is processed by the liver in much the same way as fructose, and even moderate drinking can raise triglycerides noticeably. If your levels are elevated, reducing or eliminating alcohol is one of the fastest ways to see improvement. Some people with mild elevations find that cutting alcohol alone brings their numbers below 150 mg/dL. Beer and sweetened cocktails are particularly problematic because they combine alcohol with sugar or refined carbohydrates.
When Medication Is Needed
Lifestyle changes are the foundation, but some people need medication, especially if triglycerides remain above 500 mg/dL or if cardiovascular risk is high. The two main drug classes work differently. Fibrates are the primary medications for isolated high triglycerides, reducing levels by 30 to 50 percent. Statins, which are primarily prescribed for high cholesterol, also lower triglycerides by 10 to 30 percent and are often used when both cholesterol and triglycerides are elevated.
Prescription omega-3s at 4 grams per day are sometimes used as an add-on therapy. Your provider will choose a medication based on how high your levels are, whether you also have cholesterol problems, and your overall risk for heart disease or pancreatitis. For people with severe hypertriglyceridemia above 1,000 mg/dL, where pancreatitis risk reaches 10 percent, medication is started alongside lifestyle changes rather than waiting to see if diet and exercise are enough.
