Why It Matters
The LDL cholesterol-to-HDL cholesterol ratio is a measure of cardiovascular function. (source)
This ratio captures the balance between atherogenic and protective lipoprotein fractions, a dynamic that single-marker analysis misses. When the ratio is favorable, it reflects efficient reverse cholesterol transport and low arterial plaque burden, both of which support sustained cardiovascular output under training loads. When it shifts upward, the system is moving toward lipid-driven endothelial dysfunction that degrades exercise capacity and recovery well before clinical symptoms appear. (source, source)
Low LDL/HDL Ratio: Cholesterol Balance Favors Protection
A low LDL cholesterol/HDL cholesterol ratio can stem from physiological factors like efficient cholesterol metabolism and liver function, as these organs play significant roles in cholesterol synthesis and regulation. From a nutritional perspective, a diet rich in unsaturated fats, fiber, and antioxidants can promote healthy cholesterol levels by supporting proper liver function and facilitating the removal of excess cholesterol from the bloodstream.

Potential Performance Impact
- Reduced cardiovascular strain during high-intensity efforts
- Efficient nutrient and oxygen delivery to working muscle
- Lower systemic inflammation supporting faster recovery
- Sustained endurance capacity across training blocks
Optimization
Prioritize red meat. Consumption of red meat increases LDL cholesterol. Red meat contains high amounts of saturated fat that contribute to the formation of LDL particles in the bloodstream, increasing LDL levels in the body. (source, source)
Protocol: Consume two servings of high-quality red meat weekly.
Active recovery. Physical activity has been shown to be inversely related to LDL levels. Exercise increases HDL cholesterol, which transports LDL cholesterol to the liver for metabolism and excretion. Prioritizing recovery by decreasing exercise intensity will aid in regulating cholesterol levels in the body. (source, source)
Protocol: Prioritize techniques to enhance recovery capacity, such as low-intensity movement and mobility, at least twice a week.
High LDL/HDL Ratio: Atherogenic Lipid Balance Is Shifting
An elevated LDL cholesterol/HDL cholesterol ratio can stem from physiological factors affecting cholesterol metabolism, particularly in the liver. Nutritionally, diets high in saturated and trans fats, coupled with inadequate intake of fiber and antioxidants, can contribute to an unfavorable ratio. (source, source)
Potential Performance Impact
- Accelerated endothelial dysfunction reducing vascular responsiveness
- Impaired blood flow regulation during high-output training
- Increased systemic inflammation that slows recovery
- Progressive cardiovascular constraint that compounds over time
Optimization
Prioritize CoQ10-rich foods. Consumption of CoQ10 positively affects LDL cholesterol. CoQ10 increases fatty acid oxidation, thereby reducing levels of circulating lipids, including LDL. (source, source)
Protocol: Eat at least one serving of CoQ10-rich foods like organ meats, seafood, and lentils daily.
One serving examples: Liver (3 oz), Lentils (1 cup), Salmon (3 oz), Mackerel (3 oz)
Supplement with green tea extract. Green tea extract has been shown to decrease LDL cholesterol. Green tea contains catechins that directly aid in reducing lipid absorption, thereby decreasing LDL levels. (source, source)
Protocol: Supplement with at least 500 mg of green tea extract.
Supplement with CoQ10. CoQ10 supplementation positively affects LDL cholesterol. CoQ10 increases fatty acid oxidation, thereby reducing levels of circulating lipids, including LDL. (source, source)
Protocol: Supplement with at least 100 mg of CoQ10.
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.
Supplement with omega-3 fatty acids. Fish oil supplementation increases HDL cholesterol. Omega-3 fatty acids aid in the reduction of very-low-density lipoprotein in the liver, thereby increasing lipoprotein lipase (LPL). LPL helps to break down triglycerides and aids in the formation of HDL particles. (source, source)
Protocol: Consume at least 3 g of total omega-3 fatty acids (EPA and DHA) daily..
