Why It Matters
The ratio of triglycerides to HDL cholesterol is a measure of cardiovascular function. (source)
This ratio serves as a surrogate marker for insulin resistance and atherogenic dyslipidemia, two conditions that erode metabolic flexibility long before they produce clinical symptoms. A favorable ratio signals that the liver is efficiently clearing triglyceride-rich particles and that HDL-mediated reverse cholesterol transport is intact, both of which support the sustained energy metabolism that high-output training demands. When the ratio climbs, it reflects a shift toward lipid storage, VLDL overproduction, and diminished vascular responsiveness that directly constrains performance capacity. (source, source)
Low Triglycerides/HDL Ratio: Lipid Metabolism Is Efficient
A low triglycerides/HDL cholesterol ratio can often stem from physiological factors involving liver function and lipid metabolism. Nutritionally, it may be influenced by dietary habits that promote a healthier lipid profile, such as consuming foods rich in omega-3 fatty acids and fiber while limiting trans fats and excessive sugar intake.

Potential Performance Impact
- Efficient fuel mobilization during prolonged efforts
- Optimal vascular function supporting oxygen delivery
- Stable energy availability without post-meal crashes
- Lower inflammatory burden, aiding recovery between sessions
Optimization
A low triglyceride to HDL ratio is a sign of good health and optimal physiology. There are no recommendations needed. Maintain current nutrition, lifestyle, and supplementation protocols.
High Triglycerides/HDL Ratio: Metabolic Flexibility Is Compromised
A high ratio of triglycerides to HDL cholesterol can stem from physiological factors such as liver function and metabolism, as the liver plays a crucial role in triglyceride synthesis and cholesterol regulation. Nutritionally, excessive consumption of refined carbohydrates, sugars, and unhealthy fats can contribute to elevated triglyceride levels and an unfavorable ratio. (source, source)
Potential Performance Impact
- Impaired fuel substrate switching during variable-intensity efforts
- Reduced cardiovascular efficiency and vascular responsiveness
- Increased post-meal fatigue and energy instability
- Progressive insulin resistance that compounds metabolic constraint
Optimization
Prioritize fatty fish. Consumption of omega-3 fatty acids has been shown to lower serum triglycerides. Omega-3 fatty acids decrease liver production of very low-density lipoproteins (VLDL) and triglycerides while also increasing breakdown and their removal from the bloodstream. (source, source)
Protocol: Eat at least two servings of fatty fish a week.
One serving examples: Salmon (3 oz), Herring (3 oz), Bluefin Tuna (3 oz), Anchovies (3 oz), Mackerel (3 oz)
Maintain an athletic body composition. Decreases in body weight have been associated with decreases in triglycerides. Increased body fat causes the body to store more triglycerides in fat cells, resulting in an increased circulating level. Additionally, increased body fat is associated with insulin resistance, which has been shown to trigger excess fatty acid release for conversion to triglycerides. (source, source, source)
Protocol: Maintain a high-performance diet and exercise program that supports a body composition of no more than 15% body fat for men and 20% for women.
Supplement with fish oil. Ingestion of omega-3 fatty acids has been shown to lower triglycerides. Omega-3 fatty acids decrease liver production of very low-density lipoproteins (VLDL) and triglycerides while also increasing breakdown and their removal from the bloodstream. (source, source)
Protocol: Supplement with at least 3 grams of fish oil daily.
Prioritize healthy fats. Consumption of fatty acids increases HDL cholesterol. Omega-3 fatty acids aid in the reduction of very low-density lipoprotein in the liver by increasing lipoprotein lipase (LPL). LPL helps to break down triglycerides and aids in the formation of HDL particles. (source, source)
Protocol: Consume at least one serving of foods containing healthy fats daily.
One serving examples: Mackerel (3 oz), Salmon (3 oz), Cashews (1 oz), Sunflower Seeds (1 oz)
Train regularly. Physical activity has been shown to increase HDL. Aerobic exercise increases HDL cholesterol by increasing lipoprotein lipase concentration and its activity in skeletal muscles. (source, source)
Protocol: Follow a structured training program that exerts your body through multiple resistance and aerobic intensities. This includes a structured aerobic program that ensures at least 150 minutes of moderate intensity (50 to 70% max heart rate) or 75 minutes of high intensity (75% max heart rate or greater) a week and a structured resistance training program with moderate to heavy loads at least twice a week. The final set of each resistance training exercise should be taken within two repetitions of failure.
