High triglycerides respond well to lifestyle changes, and most people can bring their levels down significantly through a combination of dietary shifts, exercise, weight loss, and cutting back on alcohol. When levels are very high, prescription medications may also be necessary. The specific approach depends on how elevated your numbers are: below 150 mg/dL is considered healthy, 150 to 199 is borderline high, 200 to 499 is high, and 500 or above is very high and carries a risk of serious complications.
Cut Back on Sugar and Refined Carbs First
Sugar and refined carbohydrates are the biggest dietary drivers of high triglycerides, often more so than fat. Your liver converts excess sugar and starch into triglycerides for storage, so reducing these foods can produce noticeable drops in your numbers within weeks. The American Heart Association recommends limiting added sugar to no more than 6 teaspoons a day for women and 9 teaspoons for men. For context, a single can of soda contains about 10 teaspoons.
The foods to watch include candy, cakes, cookies, ice cream, pastries, and sweetened yogurts. Sugary drinks are particularly problematic: regular soda, fruit-flavored drinks, lemonade, sweetened coffee drinks, sports drinks, and energy drinks all deliver large sugar loads quickly. Starchy refined foods like white bread, white rice, regular pasta, crackers, and corn can also spike triglycerides. Swapping these for 100% whole grain versions (whole wheat bread, brown rice, whole grain pasta) makes a meaningful difference because the fiber slows digestion and blunts the triglyceride response.
How Exercise Lowers Triglycerides
Physical activity can reduce triglycerides by up to 30%, making it one of the most effective single interventions available. The general recommendation is at least 150 minutes of moderate-intensity exercise per week, or 75 minutes of vigorous activity. That breaks down to something as simple as a brisk 30-minute walk five days a week. The benefit comes from regular movement over time, not from occasional intense workouts, so consistency matters more than intensity. If you’re currently inactive, even starting with 10 to 15 minutes a day and building up gradually will move your numbers in the right direction.
Weight Loss and Triglycerides
Losing weight has a direct, dose-dependent effect on triglyceride levels. Even modest weight loss helps. People who lose less than 5% of their starting weight still see a significant reduction in triglycerides. Those who lose 5 to 10% see larger improvements, and losing more than 10% produces even greater drops. For someone who weighs 200 pounds, that means losing as little as 8 to 10 pounds can start making a measurable difference. The triglyceride reduction from weight loss tends to happen alongside improvements in total cholesterol and LDL cholesterol, so the cardiovascular benefits compound.
Alcohol’s Outsized Effect
Alcohol raises triglycerides through a specific mechanism: it stimulates the liver to produce more of the particles that carry triglycerides into the bloodstream. This effect is strong enough that even moderate drinking can elevate fasting triglyceride levels in otherwise healthy people. If your triglycerides are already high, reducing or eliminating alcohol is one of the fastest ways to see improvement. Clinical recommendations range from complete abstinence for people with significantly elevated levels to cautious, limited use in milder cases. If your levels are above 500 mg/dL, cutting out alcohol entirely is the safest approach.
Omega-3 Fatty Acids: Food, Supplements, and Prescriptions
Omega-3 fatty acids lower triglycerides in a dose-dependent way. For every additional gram of omega-3s consumed daily, triglyceride levels drop by roughly 6 mg/dL, with stronger effects in people who start with higher levels. Eating fatty fish like salmon, mackerel, sardines, and trout two to three times a week is a reasonable starting point for mildly elevated triglycerides.
For significantly high levels, though, food alone won’t deliver enough omega-3s. The American Heart Association has concluded that 4 grams per day of prescription omega-3s (containing EPA plus DHA, or EPA alone) effectively lower triglycerides. This is a therapeutic dose that’s difficult to reach through diet or store-bought supplements.
The distinction between prescription omega-3s and over-the-counter fish oil supplements is important. Prescription versions go through rigorous FDA approval for safety, efficacy, purity, and manufacturing quality. Dietary supplements, by contrast, are regulated as food, not medication. The FDA has no authority to review their safety or effectiveness before they hit store shelves. Independent testing has repeatedly found that fish oil supplements contain variable amounts of EPA and DHA, inconsistencies with what’s listed on the label, and sometimes contaminants, cholesterol, saturated fats, or oxidation products. If your doctor recommends high-dose omega-3 therapy, a prescription formulation is the reliable option.
When Medication Is Needed
Lifestyle changes are the first-line treatment for high triglycerides, but when levels remain elevated despite diet and exercise, or when they’re very high to begin with, prescription medications may be necessary. Fibrates are the most commonly used drug class specifically for triglyceride lowering. They typically reduce triglyceride levels by 30 to 50% while also raising HDL (“good”) cholesterol by 5 to 15%. Gemfibrozil and fenofibrate are the most widely prescribed options.
Prescription omega-3s (discussed above) are another option, sometimes used alongside other cholesterol-lowering medications. In a large trial of over 8,000 patients, a prescription EPA formulation taken at 4 grams per day for nearly 5 years significantly reduced cardiovascular events in people with elevated triglycerides who were already on statin therapy.
Why Very High Levels Need Urgent Attention
Triglycerides above 500 mg/dL aren’t just a long-term heart risk. They carry an increasing risk of acute pancreatitis, a painful and potentially dangerous inflammation of the pancreas. The risk climbs progressively above 500, becomes roughly 5% once levels exceed 1,000 mg/dL, and reaches 10 to 20% at levels above 2,000 mg/dL. If your triglycerides are in this range, treatment typically involves both immediate medication and aggressive lifestyle changes to bring the numbers down quickly and prevent a pancreatitis episode.
Putting It All Together
The most effective approach combines several strategies at once rather than relying on any single change. Cutting sugar and refined carbs, adding regular exercise, losing a moderate amount of weight, and reducing alcohol work synergistically. For borderline or moderately high triglycerides (150 to 499 mg/dL), these lifestyle changes alone are often enough. For very high levels (500 and above), medication is typically added from the start while lifestyle modifications take effect. Most people see meaningful improvement within a few months of consistent changes, and follow-up blood work can confirm whether your approach is working or needs adjustment.
