Your Blood Fat Fuel
Triglycerides are the main form of fat circulating in your blood. After you eat, your body converts unused calories into triglycerides and stores them in fat cells for later energy. High triglycerides mean you're consistently taking in more energy than you're burning—and the excess is floating around your bloodstream.
What is Triglycerides?
Triglycerides are the most common type of fat in your body. They come from food and are also made by your liver. Fasting levels reflect how well your body processes dietary fat and carbohydrates.
↑ What High Triglycerides Means
Your blood has too much circulating fat. This coats your artery walls alongside LDL and dramatically increases your risk of heart disease and pancreatitis. Very high levels (>500) can trigger a pancreatic emergency.
Common symptoms:
Usually asymptomatic until very high · Xanthomas (fatty deposits under skin) at very high levels · Pancreatitis symptoms: severe abdominal pain, nausea (>500 mg/dL)
↓ What Low Triglycerides Means
Very low triglycerides are uncommon but can indicate malnutrition, malabsorption, or hyperthyroidism.
Common symptoms:
Usually asymptomatic · Possible sign of malabsorption if very low
Why It Matters
When normal:
Lower cardiovascular disease risk
Healthy energy metabolism
Reduced pancreatitis risk
Better insulin sensitivity
Risks if abnormal:
Heart disease and atherosclerosis
Acute pancreatitis at very high levels
Metabolic syndrome
Fatty liver disease
Insulin resistance
What Can Cause Abnormal Levels?
Excess Carbohydrate and Sugar Intake
70% likelyYour liver converts excess carbs (especially refined sugars and starches) directly into triglycerides. This is the #1 dietary driver.
Excess Caloric Intake
60% likelyConsistently eating more than you burn stores the surplus as triglycerides.
Alcohol Consumption (if applicable)
Alcohol is calorie-dense and your liver prioritizes metabolizing it, leaving triglycerides to accumulate.
Insulin Resistance
When cells resist insulin, the liver overproduces triglycerides as a metabolic spillover.
Hypothyroidism
Low thyroid slows fat metabolism, causing triglyceride buildup.
Sedentary Lifestyle
Without exercise, your muscles aren't burning triglycerides for fuel.
What You Can Do
Cut refined sugars and processed carbs: sodas, white bread, pastries
Impact: Can reduce triglycerides 20-50% \u00B7 Timeline: 2-4 weeks
Fatty fish 2-3x/week: salmon, mackerel, sardines
Impact: Omega-3s directly lower triglyceride production \u00B7 Timeline: 4-8 weeks
Reduce alcohol intake (if applicable)
Impact: Can drop triglycerides 10-30% \u00B7 Timeline: 2-4 weeks
If lifestyle changes aren't enough:
Omega-3 fish oil: 2-4g EPA+DHA daily
Impact: Reduces triglycerides 15-30% \u00B7 Timeline: 4-8 weeks
30+ minutes of aerobic exercise 5x/week
Impact: Burns triglycerides directly as fuel \u00B7 Timeline: 4-8 weeks
Lose 5-10% body weight if overweight
Impact: Reduces triglycerides 20-40% \u00B7 Timeline: 3-6 months
Recommended retest: 3 months after lifestyle changes
