Weight loss can effectively lower cholesterol levels by reducing excess body fat, which helps decrease LDL (bad) cholesterol and triglycerides. A healthy, balanced diet combined with regular physical activity can promote weight loss and improve cholesterol levels. Incorporating more fruits, vegetables, whole grains, and lean proteins while reducing saturated fats and trans fats is beneficial. Consistent exercise, such as brisk walking, swimming, or cycling, can also support weight loss and heart health.
