Lowering triglycerides comes down to a handful of changes that target how your liver produces and releases fat into your bloodstream. Normal levels fall below 150 mg/dL after a 12-hour fast, borderline high runs 150 to 199 mg/dL, high is 200 to 499 mg/dL, and anything at or above 500 mg/dL is considered very high. Where you fall on that scale determines how aggressively you need to act, but the strategies that work are the same across the board.
Why Triglycerides Rise in the First Place
Your liver packages triglycerides into particles called VLDL and releases them into your bloodstream. This is a normal, necessary process. The problem starts when you give your liver more raw material than it needs. Excess sugar, excess alcohol, and excess calories all funnel into the same pathway: your liver converts the surplus into fat, wraps it in VLDL, and ships it out. When production outpaces your body’s ability to clear those particles, triglycerides accumulate in your blood.
Fructose is a particularly efficient driver of this process. Unlike glucose, fructose enters liver cells without needing insulin, which means it bypasses the normal metabolic checkpoints that would slow things down. Once inside the liver, it ramps up the enzymes responsible for converting carbohydrates into fat. This is why cutting added sugars, especially fructose from sweetened beverages, juice, and processed foods, has an outsized effect on triglyceride levels compared to cutting other calories.
Cut Added Sugars and Refined Carbs
Sugar-sweetened drinks, fruit juices, candy, white bread, and other refined carbohydrates are the single biggest dietary contributor to elevated triglycerides. Your body rapidly converts these foods into the building blocks of fat inside the liver. Reducing your intake of added sugars is often enough on its own to move borderline-high levels back into the normal range.
You don’t need to eliminate all carbohydrates. The goal is to swap refined sources for whole grains, legumes, vegetables, and fruits that come with fiber. Fiber slows the rate at which sugar reaches your liver, which keeps the fat-production machinery from running at full speed. A practical starting point: stop drinking anything with added sugar. That single change removes a major source of fructose for most people.
Choose Better Fats
Replacing saturated fats (butter, fatty cuts of meat, full-fat dairy, coconut oil) with polyunsaturated and monounsaturated fats lowers triglycerides and improves your overall cholesterol profile. Good sources include olive oil, avocados, nuts, seeds, and fatty fish like salmon and sardines.
The shift matters more than the total amount of fat you eat. Swapping saturated fat or refined carbs for polyunsaturated fat reduces triglycerides, while doing the reverse raises them. If you’re cooking with butter, switching to olive oil is a straightforward win. If you’re snacking on chips, swapping in a handful of walnuts targets the same pathway from the opposite direction.
Omega-3 Fatty Acids: Food and Supplements
Omega-3 fats from fish oil are one of the most studied interventions for high triglycerides. A large Cochrane review of 86 trials found that omega-3 supplements reduced triglycerides by about 15% on average. The effect follows a dose-response curve: each additional gram per day of EPA and DHA (the two active omega-3s) lowers triglycerides by roughly 6 mg/dL, with a stronger effect in people whose levels are higher to begin with.
For people with significantly elevated levels, the American Heart Association recognizes 4 grams per day of EPA and DHA as an effective dose, though amounts that high typically come through prescription formulations rather than over-the-counter fish oil capsules. Standard fish oil supplements contain around 300 to 500 mg of combined EPA and DHA per capsule, so reaching therapeutic doses with store-bought supplements would mean taking many capsules daily. Eating fatty fish two to three times per week is a reasonable food-first approach that also delivers protein and displaces less healthy options from your plate.
Exercise Lowers Triglycerides Two Ways
Physical activity attacks triglycerides from both the production side and the clearance side. Two months of high-intensity interval training reduced the liver’s triglyceride output by about 35% in one study, which translated to a 28% drop in fasting blood levels. That’s a meaningful reduction from exercise alone, without any dietary change.
Even a single session of vigorous exercise, whether aerobic or resistance-based, boosts your body’s ability to pull triglyceride particles out of the bloodstream by 25% to 40% in the 12 to 24 hours following the workout. This clearance effect is temporary, which is why consistency matters more than intensity. Regular activity keeps this cleanup mechanism running day after day. Aim for at least 150 minutes per week of moderate activity or 75 minutes of vigorous activity. Walking counts, especially if your current baseline is sedentary.
Lose a Modest Amount of Weight
You don’t need to reach an ideal body weight to see results. Losing just 5% to 10% of your body weight can reduce triglycerides by about 20%. For someone who weighs 200 pounds, that’s a 10- to 20-pound loss. The triglyceride benefit comes partly from the calorie deficit itself (less surplus for the liver to convert to fat) and partly from the reduction in visceral fat that surrounds and infiltrates the liver.
The method of weight loss matters less than the result. Any sustainable approach that puts you in a modest calorie deficit will produce the triglyceride benefit. Combining dietary changes (especially sugar reduction) with increased physical activity tends to be more effective than either strategy alone, because you’re simultaneously reducing what goes into the liver and improving how quickly your body clears fat from the blood.
Limit Alcohol
Alcohol’s relationship with triglycerides is complex. Moderate amounts don’t appear to dramatically increase the liver’s triglyceride production rate in healthy people. A study using isotope-labeled tracers found that 48 grams of alcohol (roughly three to four standard drinks) didn’t raise VLDL-triglyceride output in normal men. However, alcohol did cause fat precursors to accumulate inside liver cells, suggesting it creates a metabolic bottleneck that can become a problem with heavier or more frequent drinking.
In people who already have elevated triglycerides, alcohol can push levels significantly higher because the liver is already overloaded. If your triglycerides are above 200 mg/dL, reducing or eliminating alcohol is one of the fastest ways to see improvement. Some people with very high levels (500 mg/dL or above) see dramatic drops within days of stopping alcohol entirely.
When Lifestyle Changes Aren’t Enough
For people whose triglycerides remain high despite dietary changes, exercise, and weight loss, medications can fill the gap. Statins, which are primarily prescribed for LDL cholesterol, have limited effect on triglycerides when used alone. In one trial, patients already taking a statin saw no meaningful change in triglycerides after eight weeks of continued statin therapy, with levels hovering around 270 to 280 mg/dL.
Adding a fibrate to statin therapy produced a different result entirely. In the same trial, the combination dropped triglycerides from roughly 270 mg/dL to about 146 mg/dL, nearly cutting them in half. Fibrates work specifically on the triglyceride pathway, making them a targeted option when lifestyle measures and statins together fall short. Prescription-strength omega-3s are another option that can be used alone or alongside other medications.
The timeline for seeing results depends on which changes you make. Cutting alcohol and sugar can produce measurable drops within two to four weeks. Exercise and weight loss effects build over one to three months. Medications typically show their full effect within six to eight weeks. Most people with borderline or moderately high levels can reach normal range through lifestyle changes alone, while those with very high levels often benefit from a combined approach.
