Cholesterol levels can begin changing within weeks of adopting healthier habits or starting medication. However, the size and speed of the improvement depend on a person’s starting cholesterol level, genetics, general health and consistency with treatment.
Doctors commonly repeat a lipid panel several weeks after treatment begins or changes, although the precise timing should be individualized. People with severely elevated cholesterol or a high risk of heart disease should not rely on lifestyle changes alone without seeking medical advice.
Reduce Saturated and Trans Fats
Reducing saturated fat is one of the most effective dietary steps for lowering low-density lipoprotein, commonly called LDL or “bad” cholesterol.
Major sources include fatty and processed meats, butter, lard, full-fat dairy products, palm oil, coconut oil and many fried or highly processed foods. These can be replaced with unsaturated fats from olive or canola oil, avocados, nuts, seeds and fish.
The American Heart Association advises people trying to reduce cholesterol to limit saturated fat substantially. A healthcare professional or dietitian can help determine an appropriate target based on individual needs.
Industrial trans fats should also be avoided whenever possible. Food labels listing “partially hydrogenated oil” indicate the presence of this type of fat.
Eat More Soluble Fiber
Soluble fiber forms a gel-like substance in the digestive system and can reduce the amount of cholesterol absorbed into the bloodstream.
Good sources include:
- Oats, oat bran and barley
- Beans, lentils, chickpeas and black-eyed peas
- Apples, pears, berries and citrus fruits
- Vegetables and some seeds
- Psyllium fiber
Fiber should be increased gradually, accompanied by sufficient water, to reduce bloating or constipation. Psyllium may affect the absorption of certain medicines, so users should ask a doctor or pharmacist how to space their doses.
The US National Heart, Lung, and Blood Institute identifies soluble fiber and plant sterols or stanols as dietary tools that can help reduce LDL cholesterol. NHLBI
Consider Plant Sterols and Stanols
Plant sterols and stanols resemble cholesterol and reduce its absorption from the digestive tract. They occur naturally in small amounts in plant foods and are also added to some fortified spreads, drinks and yoghurts.
Consuming approximately two grams a day may produce an additional reduction in LDL for some people when combined with an otherwise heart-healthy diet. Supplements and fortified products are not suitable for everyone, however, and should not replace prescribed cholesterol medication.
Choose Heart-Healthy Fats
Unsaturated fats can improve the overall cholesterol profile when they replace saturated fats rather than simply being added to the diet.
Suitable choices include olive, canola and other non-tropical vegetable oils, as well as avocados, walnuts, almonds, chia seeds and other nuts or seeds.
Portion control remains important because all fats are high in calories.
Include Fish in a Balanced Diet
Fatty fish such as salmon, sardines, mackerel and trout provide omega-3 fatty acids. Omega-3s are particularly useful for lowering elevated triglycerides, but they should not be expected to produce a major direct reduction in LDL cholesterol.
Eating fish in place of fatty or processed meat can still support cardiovascular health by reducing saturated-fat intake. Fish-oil supplements should not be used as a substitute for prescribed treatment without medical guidance.
Exercise Regularly
Adults should generally aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week. Brisk walking, cycling, swimming and dancing are useful options.
Regular exercise can improve cardiovascular fitness, support weight management and help control triglycerides. The American Heart Association also recommends incorporating muscle-strengthening activity at least twice weekly. American Heart Association
People who have been inactive or have heart, breathing or mobility problems should consult a healthcare professional before beginning vigorous exercise.
Work Toward a Healthy Weight
For people who are overweight, even modest weight loss may improve LDL cholesterol, triglycerides, blood pressure and blood-sugar control.
Sustainable changes are generally more effective than extreme diets. These may include reducing portion sizes, replacing sugary drinks with water and choosing vegetables, fruit, legumes, lean protein and whole grains more frequently.
Limit Sugar, Refined Carbohydrates and Alcohol
Added sugars and highly refined carbohydrates can contribute to elevated triglycerides, particularly when consumed in large quantities.
Sugary drinks, sweets, pastries, white bread and heavily processed snacks should therefore be limited. Alcohol can also raise triglyceride levels and may need to be reduced or avoided, especially when triglycerides are already high.
Stop Smoking and Using Nicotine
Smoking damages blood vessels and increases the risk of heart attack and stroke. It can also lower protective high-density lipoprotein, or HDL, cholesterol.
Stopping smoking produces cardiovascular benefits even when changes in cholesterol numbers are modest. Support from a healthcare professional, counselling program or approved stop-smoking treatment can improve the chances of quitting successfully.
When Medication May Be Necessary
Lifestyle changes remain essential, but they may not be sufficient for people with cardiovascular disease, diabetes, inherited cholesterol disorders or very high LDL levels.
Common cholesterol-lowering treatments include:
- Statins: Medicines such as atorvastatin and rosuvastatin reduce the liver’s production of cholesterol. Depending on the medicine and dose, they can lower LDL by approximately 30% to more than 50%.
- Ezetimibe: This medicine reduces cholesterol absorption in the intestine and may be prescribed alone or alongside a statin.
- PCSK9-targeting treatments: Injectable medicines such as evolocumab and inclisiran can produce substantial additional LDL reductions in appropriate patients.
Medication selection depends on a person’s cholesterol level, cardiovascular risk, medical history, other medicines and tolerance of treatment. These drugs require professional prescribing and should not be started, stopped or adjusted without medical advice.
When Should Cholesterol Be Retested?
A clinician may repeat a lipid panel about four to 12 weeks after beginning or changing cholesterol-lowering treatment to assess the response. The interval may differ when monitoring lifestyle changes alone.
A fasting test is not always necessary, but it may be requested when triglycerides are high or when a clinician needs particular measurements. After cholesterol levels stabilize, further monitoring is generally arranged according to the patient’s risk and treatment plan.
The latest cholesterol guidance emphasizes that lower LDL levels are especially important for people at increased risk of heart attack or stroke. American College of Cardiology
Anyone with extremely high cholesterol, chest pain, a history of cardiovascular disease or a strong family history of early heart attacks should seek medical evaluation rather than waiting to see whether dietary changes work.
