You can lower triglycerides through a combination of dietary changes, regular exercise, and weight loss, with most people seeing initial improvements in blood work within a few weeks. Normal triglycerides fall below 150 mg/dL. Levels between 150 and 199 are considered mildly elevated, 200 to 499 moderately elevated, and anything above 500 severely elevated. The strategies that work best depend on how high your levels are, but lifestyle changes are the foundation at every stage.
Cut Back on Sugar and Refined Carbs
This is the single most impactful dietary change for most people with elevated triglycerides. Your liver converts excess sugar, particularly fructose, into fat with unusual efficiency. Unlike other sugars, fructose bypasses the normal regulatory checkpoints in the liver and feeds directly into fat production. That fat gets packaged into triglyceride-rich particles and released into your bloodstream.
Chronic fructose consumption makes the problem worse over time. The liver actually ramps up its fat-producing machinery in response to a steady fructose supply, increasing both the number and activity of enzymes devoted to converting sugar into fat. This creates a feedback loop: the more fructose you eat regularly, the more efficiently your liver turns it into triglycerides. The process also generates uric acid as a byproduct, which contributes to fatty liver independently.
The biggest sources to target are sweetened beverages (soda, juice, sweet tea, energy drinks), desserts, and foods with added sugars. White bread, white rice, and other refined carbohydrates break down quickly into glucose and have a similar, though less pronounced, effect. Replacing these with whole grains, vegetables, and legumes can produce noticeable changes in your next blood panel.
Rethink Your Relationship With Alcohol
Alcohol raises triglycerides through a different mechanism than sugar. Rather than increasing the liver’s production of triglyceride-rich particles, alcohol slows the rate at which your body clears them from the bloodstream. In one controlled study, a moderate dose of alcohol raised plasma triglycerides by 43% without changing production rates at all. The triglycerides were being made at the same speed; they just weren’t being removed.
If your triglycerides are already elevated, even moderate drinking can keep them stubbornly high. For people with levels above 500 mg/dL, where the risk of pancreatitis becomes real, eliminating alcohol entirely is often necessary. For those with mildly or moderately elevated levels, cutting back substantially or stopping for a period can help you see where your baseline actually sits without alcohol’s interference.
Exercise Consistently
Regular aerobic exercise lowers triglycerides by reducing the amount of fat your liver packages and releases into your blood. High-intensity interval training has been shown to cut the liver’s triglyceride output by roughly 35%, leading to about a 28% drop in circulating triglyceride levels. That’s a meaningful reduction from exercise alone.
You don’t need to start with high-intensity workouts to benefit. Brisk walking, cycling, swimming, or any activity that elevates your heart rate for 30 minutes most days of the week will help. The key is consistency. A single workout temporarily improves triglyceride clearance, but sustained reductions require weeks of regular activity. Think of it as training your liver to export less fat, not just burning calories.
Lose a Modest Amount of Weight
You don’t need to reach an ideal body weight to see results. Even a relatively small amount of weight loss can dramatically change what’s happening inside your liver. In one study, participants who lost about 4.3% of their body weight over two weeks reduced the fat stored in their livers by roughly 42%. For someone weighing 200 pounds, that’s less than 9 pounds.
The triglyceride-lowering effect of weight loss is partly about reducing the raw materials available for fat production and partly about improving insulin sensitivity, which helps your body regulate fat metabolism more effectively. Diets that emphasize lower carbohydrate intake tend to produce faster triglyceride reductions than low-fat diets at the same calorie level, likely because they address both the calorie surplus and the sugar-driven fat production simultaneously.
Increase Omega-3 Fatty Acids
Omega-3 fats from fish and fish oil are one of the few supplements with strong evidence for lowering triglycerides. The effect follows a dose-response pattern: each additional gram of omega-3s per day lowers triglycerides by about 5.9 mg/dL, with stronger effects in people whose levels are higher to begin with. Eating fatty fish like salmon, mackerel, sardines, or herring two to three times per week is a reasonable dietary starting point.
For people with significantly elevated triglycerides, dietary omega-3s alone usually aren’t enough. The American Heart Association recognizes prescription omega-3 formulations at 4 grams per day as an effective treatment for high triglycerides, either alone or alongside other medications. Over-the-counter fish oil supplements vary widely in their EPA and DHA content, so if you’re considering supplementation beyond dietary sources, it’s worth discussing the right dose and formulation with your doctor.
Follow a Mediterranean-Style Eating Pattern
Rather than focusing on individual foods, shifting your overall dietary pattern can produce compounding benefits. A Mediterranean-style diet, rich in olive oil, fish, nuts, vegetables, legumes, and whole grains while low in processed foods and added sugars, addresses multiple triglyceride drivers at once. When combined with specific cholesterol-lowering foods like oats, barley, nuts, and soy products (sometimes called a Portfolio Diet), this approach has reduced triglycerides by about 16% in people with elevated lipids.
This kind of eating pattern works because it simultaneously reduces refined carbohydrate intake, increases omega-3 consumption, provides more fiber (which slows sugar absorption), and replaces saturated fats with unsaturated ones. It’s also more sustainable than restrictive diets, which matters because triglyceride management is a long-term project.
How Long Results Take
Early improvements can show up within days to weeks of making dietary changes or starting an exercise routine. More substantial, measurable reductions typically appear at the 6 to 12 week mark, which is why most doctors recommend rechecking blood work about three months after starting lifestyle modifications. Lasting, stable results generally take at least six months of consistent effort.
When you get your levels checked, a fasting blood draw (nothing to eat or drink except water for 9 to 12 hours) gives the most accurate triglyceride reading. Non-fasting tests can be used for initial screening, and the American Heart Association considers a non-fasting level above 200 mg/dL a reliable flag for elevated triglycerides. If a non-fasting result comes back high, your doctor will likely order a fasting test two to four weeks later to confirm.
When Lifestyle Changes Aren’t Enough
For people with moderately to severely elevated triglycerides who don’t reach their target through diet, exercise, and weight loss alone, medications become part of the conversation. The most commonly prescribed class works by helping the body break down triglyceride-rich particles faster while simultaneously reducing the liver’s fat output. The degree of improvement varies based on how high your levels are to begin with and which specific medication is used.
Prescription-strength omega-3 formulations are another option, particularly for people already taking a statin whose triglycerides remain elevated. These are dosed much higher than typical supplements and have been shown to reduce cardiovascular risk in large clinical trials. For anyone with triglycerides above 500 mg/dL, medication is generally started immediately alongside lifestyle changes because of the risk of acute pancreatitis at those levels.
