You can reduce triglycerides significantly through a combination of dietary changes, regular exercise, and, when levels are very high, medication. Most people with moderately elevated triglycerides can bring them back to a healthy range with lifestyle changes alone, often within 4 to 12 weeks. A fasting level below 150 mg/dL is considered normal for adults, and anything at or above that threshold is where cardiovascular risk starts to climb.
What Your Triglyceride Numbers Mean
Triglycerides are fats your body makes from excess calories, especially from sugar and alcohol. When your blood carries too many of them, they contribute to the buildup of plaque in your arteries and raise your risk of heart disease. The cardiovascular risk is highest once levels reach 500 to 880 mg/dL, and at 500 mg/dL or above, you also face a rising risk of acute pancreatitis, a painful and potentially dangerous inflammation of the pancreas. That risk becomes particularly serious at 1,000 mg/dL or higher.
For adults, a fasting reading below 150 mg/dL is the target. Children have lower thresholds: under 90 mg/dL is considered acceptable for ages 10 to 19, and under 75 mg/dL for children under 10.
Cut Back on Sugar and Refined Carbs
This is the single most impactful dietary change you can make. Your liver converts excess sugar, particularly fructose, into fat. Fructose specifically stimulates the liver’s fat-making machinery and creates conditions that accelerate triglyceride production after meals. That means sugary drinks, candy, baked goods, and even large servings of fruit juice are direct drivers of high triglycerides.
Refined carbohydrates like white bread, white rice, and pasta have a similar effect. These foods cause a rapid spike in blood sugar and insulin, which signals your liver to package more fat into particles it releases into your bloodstream. Lab studies show that liver cells exposed to higher glucose concentrations nearly double their rate of triglyceride output compared to cells in a low-glucose environment. In practical terms, swapping white bread for whole grain, choosing brown rice over white, and cutting sweetened beverages can meaningfully lower your numbers within weeks.
Exercise Consistently
Physical activity can reduce triglycerides by up to 30%, which puts it on par with some medications. The standard recommendation is at least 150 minutes of moderate-intensity exercise per week, or 75 minutes of vigorous activity. That could look like a brisk 30-minute walk five days a week.
The effect comes from exercise burning triglycerides directly as fuel and improving your body’s ability to clear fat from the bloodstream. Both aerobic exercise (walking, cycling, swimming) and resistance training help. You don’t need to train like an athlete. Consistency matters more than intensity. If you’re currently sedentary, even starting with 10- to 15-minute walks and building from there will move the needle.
Lose a Moderate Amount of Weight
You don’t need to hit an ideal weight to see results. Losing just over 5% of your body weight (about 10 pounds for someone who weighs 200) is associated with an 11% drop in triglycerides and a nearly 6% increase in HDL, the protective form of cholesterol. That combination meaningfully shifts your overall lipid profile in the right direction.
The reverse is also true. People who gain more than 5% of their body weight see their triglyceride-to-HDL ratio climb by about 20%, a marker that tracks closely with cardiovascular risk. The good news is that even modest, sustained weight loss creates a compounding benefit across multiple lipid markers simultaneously.
Eat More Omega-3 Fats
Omega-3 fatty acids from fatty fish (salmon, mackerel, sardines, herring) help your liver produce fewer triglyceride-rich particles. Eating fish two to three times per week is a reasonable dietary goal, but food alone typically doesn’t deliver enough omega-3s to produce a dramatic drop if your levels are already high.
For people with triglycerides between 200 and 499 mg/dL, prescription-strength omega-3 supplements at 4 grams per day lower triglycerides by roughly 20% to 30%. At very high levels (500 mg/dL and above), the same dose can achieve reductions of 30% or more. The American Heart Association considers this dosage both effective and safe, either on its own or alongside other lipid-lowering treatments. Over-the-counter fish oil supplements contain lower concentrations and aren’t standardized the same way, so they’re less reliable for therapeutic results.
Limit Alcohol
Alcohol is efficiently converted to fat by your liver, and even moderate drinking can raise triglycerides in people who are sensitive to it. If your levels are elevated, cutting alcohol entirely for a few weeks is a useful experiment. Some people see a dramatic drop from this change alone. If your triglycerides are above 500 mg/dL, eliminating alcohol is strongly recommended because of the added pancreatitis risk.
Add Soluble Fiber
Soluble fiber, found in oats, beans, lentils, apples, and flaxseed, forms a gel in your digestive tract that slows the absorption of fats and sugars. Getting 5 to 10 grams of soluble fiber daily improves your lipid profile. A bowl of oatmeal provides about 2 grams, a cup of cooked black beans about 5 grams. Building fiber intake gradually helps you avoid bloating while making the change sustainable.
When Medication Becomes Necessary
Current guidelines define persistent high triglycerides as levels at or above 150 mg/dL that haven’t responded to at least 4 to 12 weeks of lifestyle changes. At that point, or when levels are dangerously high, medication enters the picture.
Fibrates are the class of drug most specifically targeted at triglycerides. They work by activating a pathway in the liver that increases the breakdown of fat, boosts the enzymes that clear triglycerides from your blood, and reduces the liver’s output of fat-carrying particles. Statins, which are primarily prescribed for LDL cholesterol, also lower triglycerides to a lesser degree and are often already part of a treatment plan for people at elevated cardiovascular risk. Prescription omega-3s, as noted above, are another option your doctor may use alone or in combination with other medications.
For people with triglycerides above 500 mg/dL, treatment typically starts more aggressively because the immediate priority is preventing pancreatitis, not just reducing long-term heart risk.
What a Practical Plan Looks Like
If you’ve just gotten a high triglyceride reading, the most effective starting combination is reducing added sugar and refined carbohydrates, adding regular exercise, and limiting alcohol. These three changes target the primary drivers for most people and can produce measurable results within a month or two. Adding omega-3-rich fish, more fiber, and gradual weight loss reinforces those gains.
Triglycerides respond to lifestyle changes faster than most other lipid markers. A recheck after 8 to 12 weeks of consistent effort gives you a clear picture of whether the changes are sufficient or whether medication should be part of the plan.
