Why It Matters
The ratio of total cholesterol to HDL cholesterol is a direct measure of cardiovascular efficiency. (source) It quantifies the balance between all circulating cholesterol and the fraction dedicated to reverse cholesterol transport, the process of removing excess cholesterol from arterial walls and returning it to the liver for excretion. A lower ratio indicates that HDL is efficiently clearing atherogenic particles, while a higher ratio signals that cholesterol accumulation outpaces removal. (source) For performance, this ratio reflects how well the vascular system manages lipid burden, directly influencing blood flow, oxygen delivery, and recovery capacity.
This ratio has demonstrated stronger predictive value for cardiovascular events than isolated LDL or total cholesterol measurements, as it captures the interplay between atherogenic and protective lipoprotein fractions in a single metric. (source)
Low Total Cholesterol/HDL Ratio: Favorable Lipid Balance
A low total cholesterol to HDL cholesterol ratio is a sign of efficient cardiovascular function. It stems from a well-functioning liver and efficient cholesterol metabolism. (source) Consuming a diet rich in healthy fats, fiber, and antioxidants supports HDL levels and maintains a favorable cholesterol ratio. (source, source)
Potential Performance Impact
- Strong reverse cholesterol transport, keeping arterial walls clear for optimal blood flow
- Efficient lipid metabolism supporting sustained energy output during prolonged effort
- Reduced systemic inflammation, supporting faster recovery between training sessions
Optimization
Prioritize red meat. Saturated fat promotes cholesterol synthesis. (source) Red meat is a source of saturated fat that drives hepatic cholesterol production upward, which can help maintain adequate total cholesterol levels when the ratio is already favorable.
Protocol: Consume two servings of high-quality red meat weekly.
High Total Cholesterol/HDL Ratio: Impaired Lipid Clearance
A high total cholesterol to HDL cholesterol ratio reflects dysfunction in cholesterol metabolism and liver regulation. Excessive intake of saturated and trans fats raises total cholesterol, while a diet lacking fiber and antioxidants suppresses HDL cholesterol levels. (source, source)
Potential Performance Impact
- Accelerated atherosclerotic plaque formation, restricting arterial diameter and oxygen delivery
- Impaired endothelial function, limiting vasodilation during high-intensity effort
- Elevated systemic inflammation, delaying recovery and increasing perceived exertion
- Increased cardiovascular strain under load, reducing sustainable work capacity
Optimization
Limit saturated fats. Replacing saturated fats with monounsaturated and polyunsaturated fats produces a measurable positive effect on cholesterol. (source) Saturated fats increase total cholesterol by suppressing LDL receptor pathways and increasing cholesterol synthesis. (source, source)
Protocol: Limit saturated fat intake to less than 15 g per day.
Prioritize fiber-rich foods. Diets high in fiber positively affect cholesterol levels. (source) Dietary fiber decreases cholesterol absorption and increases excretion through bile and fecal matter, reducing total cholesterol levels. (source, source)
Protocol: Incorporate fiber-rich foods with the target of at least 30 g of fiber per day. One serving examples: Chia Seeds (2 tbs), Flaxseeds (2 tbs), Lentils (1 cup), Steel Cut Oats (1 cup), Avocado (1 medium).
Prioritize CoQ10-rich foods. Consumption of CoQ10 positively impacts total cholesterol. (source) CoQ10 aids in the downregulation of the lectin-like oxidized LDL receptor and reduces endothelial damage caused by reactive oxygen species. It improves HDL-mediated cholesterol efflux capacity and increases fatty acid oxidation. (source)
Protocol: Eat at least one serving of CoQ10-rich foods daily. One serving examples: Liver (3 oz), Lentils (1 cup), Salmon (3 oz), Mackerel (3 oz).
Prioritize healthy fats. Consumption of DHA and EPA increases HDL cholesterol levels and reduces total cholesterol. (source, source) Omega-3 fatty acids enhance cholesterol transport and excretion. (source) They reduce VLDL production in the liver, increasing lipoprotein lipase activity and HDL particle formation. (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. Both resistance and aerobic training promote healthy cholesterol levels. (source) Exercise stimulates cholesterol transportation pathways, supporting metabolism and excretion. (source, source) Exercise promotes lipoprotein lipase activity, supporting triglyceride metabolism and increasing HDL concentrations. (source, source)
Protocol: Follow a structured training program including 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) per week, plus structured resistance training with moderate to heavy loads at least twice per week. The final set of each resistance exercise should be taken within two repetitions of failure.
Maintain an athletic body composition. Body fat percentage is positively correlated with total cholesterol levels. (source) Excess body fat increases insulin resistance, which reduces lipoprotein lipase and increases hepatic lipase, negatively affecting HDL cholesterol. (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 CoQ10. Supplementation with CoQ10 decreases total cholesterol. (source) CoQ10 aids in downregulation of the lectin-like oxidized LDL receptor and reduces endothelial damage from reactive oxygen species. It improves HDL-mediated cholesterol efflux capacity and increases fatty acid oxidation. (source)
Protocol: Supplement with at least 100 mg of CoQ10.
Supplement with berberine. Berberine supplementation decreases total cholesterol. (source) Berberine increases the production of cell-surface LDL receptors by increasing the stability of LDLR mRNA during translation. LDLRs uptake cholesterol from circulation into cells, lowering serum LDL levels. (source, source)
Protocol: Supplement with at least 1 g of berberine daily.
Supplement with fish oil. Supplementation with DHA and EPA increases HDL cholesterol levels and reduces total cholesterol. (source) Omega-3 fatty acids enhance cholesterol transport and excretion. (source) They reduce VLDL production in the liver, increasing lipoprotein lipase activity and HDL particle formation. (source)
Protocol: Supplement with at least 3 grams of fish oil daily.
