How to improve HDL levels?

How to Improve HDL Cholesterol Levels

Regular physical activity is the most effective lifestyle intervention for increasing HDL cholesterol levels, with at least 30 minutes of moderate-intensity aerobic exercise 5 times weekly recommended as the foundation for HDL improvement. 1

Exercise Recommendations

• Engage in prolonged moderate-intensity aerobic exercise at 70-80% heart rate reserve, combined with low-intensity resistance training at 50% of 1 repetition maximum (1RM) for healthy individuals 2, 1
• For those with dyslipidemia, progress to 85% maximum heart rate with moderate to high-intensity resistance training at 75-85% 1RM 2, 1
• There is a linear dose-response relationship between activity levels and HDL cholesterol levels - more activity generally yields greater HDL increases 2, 3
• Aim for a minimum caloric expenditure of 1200-1600 kcal per week (equivalent to 7-14 miles of jogging) to achieve significant HDL improvements 3
• The combination of aerobic exercise and resistance training provides enhanced benefits for the overall lipid profile compared to either modality alone 2, 1
• For individuals with limited mobility, resistance training progressing from 50% to 75% 1RM in major muscle groups can be incorporated into circuit sessions 2

Dietary Modifications

• Replace saturated fats with monounsaturated fats (such as olive oil) and polyunsaturated fats rather than with carbohydrates to maintain or improve HDL levels 1, 4
• Limit refined carbohydrates and sugars, as high-carbohydrate diets can reduce HDL cholesterol levels 2, 4
• Avoid trans-unsaturated fatty acids, which can lower HDL cholesterol 1, 4
• Consider moderate alcohol consumption, which can raise HDL levels, but this should be balanced against other health considerations 5
• Consume a diet rich in vegetables, fruits, and whole grains with high fiber content 4

Weight Management

• Achieve and maintain a healthy weight through caloric control 1, 4
• Weight reduction is particularly important for those with elevated triglycerides and low HDL cholesterol 2, 4
• Combining a healthy diet with weight loss and physical activity can increase HDL-C by 10% to 13% 6

Other Lifestyle Modifications

• Quit smoking, as smoking cessation can increase HDL cholesterol levels by up to 30% 1, 7
• Control acute metabolic syndrome if present, as this condition is associated with low HDL levels 7

Pharmacological Options

• Niacin (nicotinic acid) is the most effective drug for raising HDL cholesterol, increasing levels by 15-35%, but can affect blood glucose levels 2, 8
• Fibrates (like fenofibrate) can effectively increase HDL cholesterol levels by 5-20% and reduce triglycerides 2
• Statins, while primarily used for LDL reduction, can also increase HDL levels by at least 5% 7

Common Pitfalls to Avoid

• Very low-fat diets (<15% energy as fat) can paradoxically lower HDL cholesterol 4
• High-carbohydrate diets, especially those high in sugars, may reduce HDL cholesterol levels 2
• Relying solely on medication without addressing underlying lifestyle factors will limit long-term success 4
• Focusing only on HDL numbers without considering overall cardiovascular risk and other lipid parameters 5

Monitoring and Follow-up

• Lipid levels should be measured every year in adults with risk factors 2, 4
• In adults with low-risk lipid values (LDL <100 mg/dl, HDL >60 mg/dl, triglycerides <150 mg/dl), lipid assessments can be repeated every 2 years 2
