Cholesterol-Lowering Diet: How Long To See Results?

how long for diet to reduce cholesterol

Lowering cholesterol is important for maintaining heart health. While there is no quick fix, cholesterol-lowering medications can be effective within 4 weeks. However, for those hoping to lower cholesterol naturally, it can take longer. This involves adopting heart-healthy lifestyle habits, such as dietary changes and increased physical activity, which can lead to a gradual decrease in cholesterol levels. The Mediterranean diet is often recommended, emphasising the reduction of saturated and trans fats, which contribute to higher LDL (bad) cholesterol levels. Additionally, soluble fibre, plant-based foods, and physical activity can help lower LDL cholesterol and improve overall health. While dietary changes may show results within 3 weeks, it's important to be patient as cholesterol levels reflect patterns that develop over time. Combining lifestyle adjustments with medication may be necessary for some individuals.

Exercise more

Exercise is a great natural way to lower your cholesterol levels. According to Dr. Leslie Cho, "Combining exercise with a healthier diet and lifestyle choices makes the most impact". The American Heart Association also states that high cholesterol is caused by a lack of exercise and being overweight.

It is recommended to get at least 200 minutes per week of exercise, including moderate-intensity aerobic exercise, which can help lower cholesterol and reduce high blood pressure. Some examples of moderate-intensity exercises include brisk walking, bicycling, dancing, gardening, swimming, jogging, and aerobics. These exercises can also help raise HDL cholesterol, or "good" cholesterol, which helps remove cholesterol and carry it back to the liver.

If you are new to exercising, it is important to start slowly and gradually increase the intensity and duration. You can start with a 15-minute walk, and then slowly increase the pace and duration. It is also important to stay hydrated, wear comfortable shoes, and listen to your body. If you experience any chest pain, shortness of breath, dizziness, or lightheadedness, stop the exercise immediately and consult your doctor.

It may take a few weeks or months for exercise to lower your cholesterol levels. A 2021 study found that regularly swimming for 16 weeks helped significantly lower lipids, including cholesterol, in people with type 2 diabetes and high blood pressure. The time it takes to see results may vary depending on individual factors, such as age, weight, and overall health.

Reduce saturated fat

Saturated fats are typically solid at room temperature and are known as "solid fats". They are found in animal-based foods such as beef, lamb, pork, poultry, full-fat dairy products, eggs, and tropical oils like coconut and palm. They can also be found in plant-based foods such as coconut, coconut oil, cocoa butter, and palm oil (palm kernel oil). These fats can cause problems with cholesterol levels, increasing the risk of heart disease.

The American Heart Association recommends limiting saturated fats to less than 6% of total daily calories, which is about 13 grams per day for someone eating 2000 calories. This can be achieved by reducing the consumption of red meat, butter, cheese, and other animal-based foods, as well as limiting fried fast food and baked goods, which are made with saturated fats.

Instead of saturated fats, one should opt for healthier fats such as unsaturated fats. These include monounsaturated and polyunsaturated fats, which are typically liquid at room temperature and can be found in canola, soybean, olive, and safflower oils. Lean meats, nuts, beans, legumes, fish, and whole grains are also recommended as part of a heart-healthy diet.

In addition to dietary changes, physical activity is important in lowering cholesterol. Even small amounts of exercise, such as a 10-minute walk during your lunch break, can boost heart health and help lower cholesterol. These lifestyle changes can take time to have an effect, and it may be several weeks or months before cholesterol levels begin to lower. In some cases, medication may be necessary to help lower cholesterol, especially if lifestyle changes are not effective.

Avoid trans fats

Lowering cholesterol can be an important part of maintaining your heart health and overall health. While there is no "quick fix", cholesterol usually lowers gradually as people adopt certain lifestyle habits.

To reduce cholesterol, it is important to avoid trans fats. Trans fats are a type of fat that is inexpensive to produce and gives food a desirable taste and texture. They are often used in fried foods and baked goods such as pastries, pizza dough, pie crust, cookies, and crackers. Trans fats can also be found in partially hydrogenated vegetable oils and meat and dairy products, such as beef, lamb, and butterfat.

The American Heart Association recommends that adults who want to lower their LDL cholesterol eliminate trans fats from their diet. This is because trans fats raise your "bad" LDL cholesterol levels and lower your "good" HDL cholesterol levels. High LDL cholesterol levels can increase the risk of cardiovascular disease, clogged arteries, and other heart health issues, while low HDL cholesterol levels can also increase the risk of heart disease and stroke.

To avoid trans fats, it is important to read nutrition labels and look for partially hydrogenated oils in the ingredient list. The American Heart Association also recommends replacing trans fats with monounsaturated or polyunsaturated fats and choosing lean meats and poultry prepared without added saturated and trans fats. It is also beneficial to maintain a diet that emphasizes fruits, vegetables, whole grains, fat-free or low-fat dairy products, poultry, fish, and nuts, while limiting red and processed meats and sugar-sweetened foods and beverages.

By avoiding trans fats and making other lifestyle changes, such as increasing physical activity, individuals can effectively lower their cholesterol levels and improve their overall health.

Limit salt and alcohol intake

While making dietary and lifestyle changes to lower cholesterol, it is important to limit salt and alcohol intake. Firstly, limiting salt intake will not directly lower cholesterol, but it can lower the risk of heart disease by helping to lower blood pressure. It is recommended that you consume no more than 2,300 milligrams (about 1 teaspoon) of salt per day. This includes all sources of sodium, including cooking, at the table, and in food products. To reduce sodium intake, opt for low-salt or "no added salt" foods and seasonings.

Secondly, alcohol consumption can also contribute to higher cholesterol levels. Alcohol adds extra calories, which can lead to weight gain, and being overweight can raise LDL (bad) cholesterol levels and lower HDL (good) cholesterol levels. Additionally, excessive alcohol consumption can increase the risk of heart disease by raising blood pressure and triglyceride levels. Therefore, it is advisable to limit alcohol intake or, if you choose to drink, stick to no more than two drinks per day for men.

In addition to limiting salt and alcohol intake, making other dietary changes can significantly impact cholesterol levels. This includes reducing saturated fat and trans fat intake, as these raise LDL cholesterol levels. Instead, opt for healthier fats such as lean meats, nuts, and unsaturated oils like olive oil. Adding soluble fiber and plant-based foods to your diet can also help lower LDL cholesterol while providing essential nutrition.

It is important to note that the effectiveness of dietary changes in lowering cholesterol may vary with age. While some people may see improvements within a few weeks, it is crucial to be patient and consistent with your nutritional plan. Combining dietary changes with physical activity can further accelerate cholesterol reduction and improve overall heart health.

Lose weight

Losing weight is an important part of lowering cholesterol, as being overweight can raise your LDL (bad cholesterol) level and lower your HDL (good cholesterol) level. Lowering your LDL cholesterol can reduce your risk of heart disease.

To lose weight, it is important to maintain a calorie deficit, which means consuming fewer calories than you burn. This can be achieved through a combination of diet and exercise.

Dietary changes that can help with weight loss include:

  • Reducing your intake of saturated fats and trans fats, which are often found in processed and fried foods.
  • Increasing your consumption of fruits, vegetables, whole grains, and nuts, which are high in dietary fibre and provide essential nutrients.
  • Limiting your alcohol intake, as alcohol adds extra calories and can contribute to weight gain.
  • Reducing your sodium intake to no more than 2,300 milligrams per day, as this can help lower blood pressure and reduce water retention, aiding in weight loss.

In addition to dietary changes, regular physical activity is crucial for weight loss. Aim for at least 150 minutes of moderate-intensity exercise, such as brisk walking, cycling, or swimming, per week. Building muscle through strength training can also help increase metabolism and promote weight loss.

It is important to note that lifestyle changes take time to show results. Be patient and consistent with your healthy habits, and seek professional guidance from a healthcare provider or nutritionist if needed.
