Yes, Reduce carbs: The best way to reduce high cholesterol is by completely stopping high carb foods (grains, lentils, potato based items). Also avoid milk protein since it causes insulin resistance. Low carb food items such as flesh foods, eggs, non starchy vegetables, avocados, saturated fat (butter, ghee, coconut oil), olive oil are very effective.
