How to increase HDL cholesterol?
HDL cholesterol, the "good" cholesterol, can be increased through regular exercise, healthy fats like olive oil and fatty fish, weight loss, and lifestyle changes. Testing your levels regularly helps track progress and optimize your heart health strategy.
Understanding HDL Cholesterol and Why It Matters
HDL (high-density lipoprotein) cholesterol is often called "good cholesterol" because it acts like a cleanup crew in your bloodstream. Unlike LDL cholesterol that can build up in your arteries, HDL actually removes excess cholesterol from your blood vessels and transports it to your liver for disposal. This protective function makes HDL a crucial player in cardiovascular health.
Research shows that for every 1 mg/dL increase in HDL cholesterol, cardiovascular disease risk decreases by 2-3%. However, about 20% of adults have HDL levels below the recommended range, putting them at increased risk for heart disease. Understanding your HDL levels through comprehensive testing is the first step toward optimizing this important biomarker.
What Are Optimal HDL Levels?
HDL cholesterol levels vary by sex due to hormonal differences. Women typically have higher HDL levels than men, partly due to estrogen's protective effects. Here's what the numbers mean:
HDL Cholesterol Level Categories
| HDL Level | Category | Risk Level | Action Needed | |
|---|---|---|---|---|
| Men: <40 mg/dL | <40 mg/dL (men) | Low | High cardiovascular risk | Immediate lifestyle changes recommended |
| Women: <50 mg/dL | <50 mg/dL (women) | Low | High cardiovascular risk | Immediate lifestyle changes recommended |
| 40-59 mg/dL | 40-59 mg/dL | Borderline | Moderate risk | Focus on diet and exercise improvements |
| ≥60 mg/dL | ≥60 mg/dL | Optimal | Protective | Maintain healthy habits |
HDL levels should be interpreted alongside other cardiovascular risk factors and biomarkers.
While higher HDL is generally better, extremely high levels (above 100 mg/dL) may paradoxically increase cardiovascular risk in some individuals. This highlights the importance of regular monitoring and working with healthcare providers to understand your complete lipid profile.
Exercise: Your Most Powerful HDL Booster
Physical activity is one of the most effective ways to increase HDL cholesterol. Studies show that regular aerobic exercise can raise HDL levels by 5-10%, with some individuals experiencing even greater improvements. The key is consistency and finding activities you enjoy enough to maintain long-term.
Best Types of Exercise for HDL
- Aerobic exercise: Aim for 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity cardio weekly
- High-intensity interval training (HIIT): Can increase HDL by up to 10% in just 8-12 weeks
- Resistance training: Combining strength training with cardio provides additional HDL benefits
- Walking: Even 30 minutes daily can improve HDL levels by 5-7%
The intensity matters less than consistency. A 2019 study in the Journal of the American Heart Association found that people who exercised regularly for six months increased their HDL by an average of 6 mg/dL, regardless of whether they did moderate or vigorous exercise.
Dietary Strategies to Raise HDL Cholesterol
Your diet plays a crucial role in HDL production and function. While genetics influence baseline HDL levels, dietary changes can lead to meaningful improvements of 5-15% in most people.
Foods That Increase HDL
- Fatty fish: Salmon, mackerel, and sardines provide omega-3 fatty acids that boost HDL
- Olive oil: Extra virgin olive oil can increase HDL by 6-7% when replacing other fats
- Nuts and seeds: Almonds, walnuts, and flaxseeds support healthy cholesterol levels
- Avocados: Rich in monounsaturated fats that improve HDL function
- Purple produce: Anthocyanins in berries, purple cabbage, and eggplant increase HDL by up to 13%
A Mediterranean-style diet, rich in these foods, has been shown to increase HDL levels by 10-15% while improving overall cardiovascular health markers. The PREDIMED study, involving over 7,000 participants, demonstrated that following a Mediterranean diet supplemented with extra virgin olive oil or nuts significantly increased HDL levels compared to a low-fat diet.
Foods and Habits to Avoid
Certain dietary choices can suppress HDL production or impair its function:
- Trans fats: Found in processed foods, these can lower HDL by 20% or more
- Excessive sugar: High sugar intake reduces HDL and increases triglycerides
- Refined carbohydrates: White bread, pastries, and sugary drinks negatively impact HDL
- Excessive alcohol: While moderate amounts may increase HDL, heavy drinking is harmful
Lifestyle Modifications for Better HDL
Beyond diet and exercise, several lifestyle factors significantly influence HDL cholesterol levels. Making strategic changes in these areas can provide additional HDL benefits and improve overall cardiovascular health.
Weight Management
Losing excess weight is one of the most effective ways to increase HDL cholesterol. Research shows that for every 7 pounds of weight loss, HDL typically increases by 1 mg/dL. Even modest weight loss of 5-10% of body weight can lead to significant improvements in HDL levels and function.
The relationship between weight and HDL is particularly important for those with metabolic syndrome or insulin resistance. These conditions often feature low HDL as a key component, and addressing weight can help break this cycle. If you're working on weight management and want to understand how it's affecting your metabolic health markers, comprehensive testing can provide valuable insights into your progress.
Quit Smoking and Manage Stress
Smoking is one of the worst things you can do for your HDL levels. It not only lowers HDL by 5-10% but also damages the HDL particles, making them less effective at removing cholesterol. The good news? HDL levels can increase by up to 10% within just 8 weeks of quitting smoking.
Chronic stress also negatively impacts HDL through increased cortisol production and inflammation. Stress management techniques that can help maintain healthy HDL levels include:
- Regular meditation or mindfulness practice
- Yoga or tai chi
- Adequate sleep (7-9 hours nightly)
- Social connections and support systems

Natural Supplements That May Help
While lifestyle changes should be your primary focus, certain supplements have shown promise in raising HDL levels. Always consult with a healthcare provider before starting any supplement regimen, especially if you're taking medications.
Evidence-based supplements for HDL support include:
Remember that supplements work best when combined with a healthy lifestyle. They're not a substitute for proper diet and exercise but can provide additional support for those struggling to reach optimal HDL levels through lifestyle changes alone.
When to Consider Medical Intervention
If lifestyle modifications haven't sufficiently improved your HDL levels after 3-6 months, it may be time to discuss medical options with your healthcare provider. Some people have genetic factors that make it difficult to raise HDL naturally.
Medical interventions may include:
- Prescription omega-3 fatty acids
- Fibrates (particularly if triglycerides are also high)
- Statins (which modestly increase HDL while lowering LDL)
- PCSK9 inhibitors for those with familial cholesterol disorders
The decision to use medication should be based on your overall cardiovascular risk profile, not just HDL levels alone. This is why comprehensive lipid testing, including advanced markers like ApoA1 and ApoB, provides a more complete picture of your cardiovascular health.
Tracking Your Progress
Improving HDL cholesterol is a gradual process that requires patience and consistency. Most lifestyle interventions take 6-12 weeks to show measurable changes in HDL levels. Regular testing helps you understand what's working and adjust your approach as needed.
When monitoring your HDL improvement journey, consider tracking:
- HDL cholesterol levels every 3-6 months
- Complete lipid panel including triglycerides and LDL
- Advanced markers like ApoA1 (the main protein in HDL particles)
- Inflammatory markers like hs-CRP that affect HDL function
- Metabolic markers if you have diabetes or prediabetes

The Bottom Line on Raising HDL
Increasing HDL cholesterol is one of the most impactful steps you can take for your cardiovascular health. While genetics play a role in your baseline HDL levels, research consistently shows that lifestyle modifications can lead to meaningful improvements for most people.
The most effective approach combines regular aerobic exercise, a Mediterranean-style diet rich in healthy fats, weight management, and stress reduction. These changes not only boost HDL but improve overall metabolic health, reducing your risk of heart disease, diabetes, and other chronic conditions.
Remember that improving HDL is a marathon, not a sprint. Focus on sustainable changes you can maintain long-term rather than dramatic short-term interventions. With patience, consistency, and regular monitoring, you can achieve and maintain healthy HDL levels that support your cardiovascular health for years to come.
