Triglycerides respond remarkably well to lifestyle changes, often dropping faster than cholesterol does when you adjust your diet and activity level. In many cases, people see meaningful reductions within just a few weeks. The strategies that work best target the root causes: excess sugar, too little movement, and surplus calories your liver converts into fat.
For reference, a healthy triglyceride level is below 150 mg/dL. Borderline high falls between 150 and 199, high ranges from 200 to 499, and anything at 500 or above is considered very high.
Cut Back on Sugar and Refined Carbs First
If you do only one thing, make it this. Fructose and refined carbohydrates are the single biggest dietary driver of high triglycerides because of how your liver processes them. Unlike glucose, which gets used throughout the body, fructose is metabolized almost exclusively by the liver. There, it’s efficiently converted into fatty acids through a process called de novo lipogenesis, literally “new fat creation.” Those fatty acids get packaged into triglycerides and released into your bloodstream.
What makes this worse over time is that chronic fructose intake doesn’t just provide raw material for fat. It also reprograms the liver to become better at making fat by activating genes that ramp up fat-producing enzymes. The result is a compounding cycle: the more sugar you eat, the more efficiently your liver turns it into triglycerides. This applies to table sugar, high-fructose corn syrup, fruit juice, sweetened beverages, and refined grains like white bread and pastries that break down quickly into simple sugars.
In one study, just two weeks of carbohydrate restriction reduced liver triglycerides by about 55%, compared to 28% with general calorie restriction alone. That’s a dramatic difference in a short window, and it highlights why targeting carbs specifically matters more than just eating less overall.
Lose a Modest Amount of Weight
You don’t need to hit an ideal body weight to see results. Losing just 5% to 10% of your total body weight can lower triglycerides by roughly 20%. For someone weighing 200 pounds, that means losing 10 to 20 pounds. The triglyceride reduction often comes early in the weight loss process, partly because your liver starts releasing less fat into the bloodstream as soon as calorie intake drops and stored liver fat decreases.
The two-week carbohydrate restriction study mentioned above involved only about 4.3% weight loss, yet liver triglycerides fell by 42% on average. That suggests the combination of modest weight loss and carb reduction is more powerful than either one alone.
Move More, Prioritize Cardio
Aerobic exercise is the most effective type of physical activity for lowering triglycerides. Walking, jogging, cycling, swimming, or any sustained activity that raises your heart rate works. Large randomized trials and meta-analyses consistently show that aerobic training lowers fasting triglyceride levels while also raising HDL (the protective cholesterol).
Aim for about 120 minutes per week at a moderate-to-vigorous intensity. In one well-designed trial comparing exercise types, participants doing aerobic training at roughly that volume saw clear metabolic improvements. Resistance training (weight lifting) has its own benefits for metabolic health, but when studied head-to-head, it doesn’t lower triglycerides as reliably as cardio does. The combination of both showed a trend toward better results than resistance training alone, so adding strength work to a cardio routine is reasonable, just don’t skip the cardio.
Add Omega-3 Fatty Acids
Omega-3 fats from fatty fish (salmon, mackerel, sardines, anchovies) are one of the few nutrients with a clear, dose-dependent effect on triglycerides. A Cochrane review of 86 randomized trials covering over 160,000 participants found that omega-3 supplementation reduced triglycerides by about 15% and slightly lowered rates of cardiovascular death.
The relationship is linear: each additional gram per day of EPA and DHA (the two active omega-3s) lowers triglycerides by about 5.9 mg/dL, with a stronger effect in people who start with higher levels. The American Heart Association recognizes 4 grams per day of EPA plus DHA as an effective dose for managing high triglycerides, though that’s a prescription-level amount. Even eating fatty fish two to three times a week or taking a standard fish oil supplement providing 1 to 2 grams of EPA/DHA daily will nudge your numbers in the right direction, especially combined with other changes.
Rethink Alcohol
Alcohol has a complicated relationship with triglycerides, but the net effect for most people with elevated levels is negative. Drinking delays the clearance of dietary fat from your bloodstream, meaning triglycerides from your last meal linger longer. There’s also evidence that alcohol can increase the liver’s production of triglyceride-rich particles, though this effect varies between individuals.
If your triglycerides are borderline or high, reducing or eliminating alcohol is one of the simplest interventions. Even moderate drinking can keep levels elevated in susceptible people. You don’t necessarily need to quit entirely, but cutting back to a few drinks per week (or none) while you’re actively trying to lower your numbers will remove a variable that works against you.
Consider Berberine
Berberine, a compound found in several plants including goldenseal and barberry, has meaningful evidence behind it for triglyceride reduction. A meta-analysis of randomized, placebo-controlled trials found that berberine lowered triglycerides by an average of about 32 mg/dL. Study participants took between 300 and 1,500 mg per day, with intervention periods lasting roughly 12 to 20 weeks. Interestingly, doses at or below 1 gram per day were more effective than 1.5 grams, suggesting more isn’t necessarily better.
Berberine works through mechanisms that overlap with some prescription medications, so it’s worth mentioning to your doctor if you take other drugs, particularly those for blood sugar management.
What About Fiber and Fasting?
Two popular recommendations deserve a reality check. Soluble fiber (from oats, beans, psyllium, and flaxseed) is excellent for lowering LDL cholesterol, but a meta-analysis in the American Journal of Clinical Nutrition found it does not significantly lower triglycerides. It’s still worth eating for overall heart health, just don’t expect it to move your triglyceride number.
Intermittent fasting, specifically the popular 16:8 pattern (eating within an 8-hour window), also shows limited evidence for triglyceride reduction in the general population. A meta-analysis of 20 studies with over 1,200 participants found no significant difference in triglyceride levels between time-restricted eating and regular eating patterns. One exception: studies involving only male participants did show a meaningful drop, suggesting the effect may vary by sex. For most people, intermittent fasting may help with overall calorie reduction and weight loss, which indirectly helps, but it doesn’t appear to have a unique triglyceride-lowering effect on its own.
How Quickly You Can Expect Results
Triglycerides are one of the most responsive blood markers to lifestyle changes. While cholesterol shifts tend to unfold over months, triglycerides can drop noticeably in as little as two weeks when you cut refined carbs and lose even a small amount of weight. Most people combining diet changes with regular exercise see significant improvement within four to eight weeks, which is a typical interval for rechecking bloodwork after starting a new plan.
The changes that produce the fastest results, roughly in order of impact: eliminating sugary drinks and refined carbs, losing 5% or more of body weight, adding consistent aerobic exercise, increasing omega-3 intake, and cutting alcohol. Stack several of these together and it’s common to see triglycerides drop by 30% to 50% without medication.
