To lower triglycerides, start with the changes that most directly reduce the extra calories your liver turns into blood fat: cut added sugar and alcohol, choose whole foods over refined carbohydrates, and move regularly. Levels can improve within days or weeks, but a fasting lipid panel after 6 to 12 weeks shows whether the plan is working. If your number is very high, contact a healthcare provider promptly because the goal may be preventing pancreatitis, not simply improving a lab result.
What triglycerides measure and when a result is high
Triglycerides are a type of fat, or lipid, in the blood. They store unused calories for energy between meals. They are chemically different from cholesterol: cholesterol helps build cells and hormones, while triglycerides are an energy store. Yet both appear on the same lipid panel, along with LDL and HDL cholesterol.
High triglyceride levels usually have no symptoms. A lipid panel is therefore the way they are found, and the test is generally done after fasting for 8 to 12 hours because a nonfasting result can read artificially high.
| Fasting triglyceride category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 150 | Less than 1.7 |
| Borderline high | 150–199 | 1.7–2.2 |
| High | 200–499 | 2.3–5.6 |
| Very high | 500 or above | 5.7 or above |
About 25% to 30% of Americans have triglyceride levels above 150 mg/dL. Discuss your result with your healthcare provider together with the rest of your lipid panel and overall health.
Find what is pushing your triglycerides up
Excess calories, especially from high-carbohydrate foods, can be converted by the liver into triglycerides and stored in fat cells. Fructose from added sugar, fruit juice, and high-fructose corn syrup strongly promotes this conversion. White bread, refined sugar, and other processed foods with added sugar are common practical targets.
Alcohol matters too. Heavy use—more than four drinks a day for men or more than three for women—is a common secondary cause of very high triglycerides. Health conditions including uncontrolled type 2 diabetes, hypothyroidism, obesity, kidney disease, and liver disease can contribute. So can some diuretics, HIV drugs, and female hormones. Some people have genetic conditions that raise triglycerides despite a healthy lifestyle.
That is why a useful next step is not guessing at a single food. Review your result, medications, alcohol intake, and relevant health conditions with your healthcare provider.
What to eat to reduce triglycerides without chasing “low-fat” labels
A diet with less than 30% of daily calories from fat is recommended for triglyceride management, but the type of fat and the carbohydrate replacing it both matter. The low-fat trend of the 1980s sometimes raised triglycerides when manufacturers added sugar to replace flavor. Instead, build meals around vegetables, whole grains, nuts, fish, and olive oil—the Mediterranean-style pattern associated with lower triglyceride levels.
- Cut added sugar and sugar-sweetened drinks. Diet alone can lower triglycerides by more than 70% for some patients.
- Choose whole fruit instead of fruit juice. Juice concentrates fructose and removes fiber that slows absorption.
- Replace refined carbohydrates such as white flour with whole grains.
- Eat oily fish two to three times weekly. Salmon, mackerel, sardines, herring, and anchovies provide omega-3 fatty acids EPA and DHA; two or more servings, about 8 oz total, can help lower triglycerides.
- Limit alcohol, or avoid alcohol altogether when triglycerides are elevated, since even moderate drinking can blunt progress.
For example, swapping a fruit drink and white-bread lunch for water, whole fruit, and a whole-grain meal removes a concentrated source of sugar while adding fiber. It is a more useful change than simply choosing a product labeled low-fat.
Use activity, weight loss, sleep, and smoking cessation together
Regular aerobic activity can lower post-meal triglycerides by 30% to 50%. A practical minimum is 150 minutes of moderate-intensity aerobic exercise each week plus two full-body strength-training sessions. Exercise increases lipoprotein lipase, an enzyme that breaks down triglycerides so muscles can use them for energy.
For people carrying excess weight, losing 5% to 10% of body weight is associated with 20% lower triglyceride levels. Diet, regular exercise, and weight loss together can lower triglycerides by more than 50%. Quitting smoking can help lower triglycerides while raising HDL cholesterol. Aim for 7 to 9 hours of restful sleep as well; poor or irregular sleep is linked to higher triglycerides.
When medication helps lower triglyceride levels
Lifestyle changes are first-line treatment. Persistent hypertriglyceridemia is generally assessed after 4 to 12 weeks of that effort before medication is added. Your healthcare provider may prescribe medication based on the level of triglycerides and the risks shown by your complete lipid profile.
- Fibrates, including fenofibrate and gemfibrozil, reduce triglycerides by 30% to 50% and mildly lower LDL.
- A statin primarily lowers LDL cholesterol but can reduce triglycerides by 10% to 20%; reductions are larger when starting triglycerides exceed 250 mg/dL.
- Prescription omega-3 fatty acids are different from over-the-counter fish oil. Icosapent ethyl reduced median triglycerides by about 20% in one trial.
- Niacin can lower triglycerides and raise HDL, but it is used only by prescription because of side effects such as flushing.
Do not substitute a store-bought fish oil supplement for prescribed omega-3 treatment. Over-the-counter supplements are not FDA-approved to treat high triglycerides.
Very high triglycerides need prompt medical attention
At 500 mg/dL or above, medication may be used primarily to prevent pancreatitis rather than only to lower cardiovascular risk. Extremely high triglycerides can trigger acute pancreatitis, a sudden painful inflammation of the pancreas that often requires hospitalization. Above 1,000 mg/dL, the risk is about 5%; above 2,000 mg/dL, it rises to 10% to 20%.
Seek urgent medical care for severe abdominal pain, and contact your clinician promptly about a very high result. Uncontrolled diabetes, heavy alcohol use, weight gain, saturated fats, and refined carbohydrates can combine with an underlying genetic lipid disorder to raise risk.
Common triglyceride myths that can delay useful changes
“Triglycerides and cholesterol are the same thing.”
They are different substances with different roles, even though the same blood test measures them. You can have high LDL cholesterol with low triglycerides; that pattern is common in familial hypercholesterolemia. By contrast, familial combined hyperlipidemia often raises both LDL and triglycerides.
“If I feel fine, a high result is harmless.”
High triglycerides usually produce no symptoms. Very high levels can increase the risk of pancreatitis, so waiting for symptoms is not a safe monitoring strategy.
“One workout fixes the problem.”
Acute exercise can lower triglycerides within 24 hours, but substantial fasting changes usually take 6 to 12 weeks of consistent lifestyle changes. Use the quick response as motivation, not as a replacement for a routine.
Frequently Asked Questions
What are healthy triglyceride levels?
A fasting value below 150 mg/dL, or below 1.7 mmol/L, is considered normal. A clinician can interpret it alongside LDL, HDL, total cholesterol, and your health history.
How are high blood triglycerides diagnosed?
They are diagnosed with a lipid panel, usually after an 8- to 12-hour fast. The test commonly measures triglycerides, total cholesterol, LDL, and HDL together.
How long does it take to lower your triglyceride levels?
Diet and exercise changes may show effects within days to weeks. More substantial fasting changes typically take 6 to 12 weeks, and follow-up testing after medication is often ordered at 4 to 12 weeks.
Can you have high LDL cholesterol but low triglycerides?
Yes. This pattern occurs in familial hypercholesterolemia, while metabolic syndrome and type 2 diabetes more often cause high triglycerides with low HDL and only mildly elevated LDL.
What are the risks of very high triglyceride levels?
The key immediate risk is acute pancreatitis. Contact a doctor promptly for a very high laboratory result, and seek urgent care for severe abdominal pain.
