Keep your body weight in a healthy range for your height and frame. Body mass index, though not a perfect measurement, can help you estimate your healthy weight. Eat plenty of vegetables and fruit (more than 5 cups a day). Try to limit your saturated fat intake to less than 10% of your total calories per day and limit your fat intake to about 30 grams per day. Eat foods high in omega-3 fatty acids. Avoid trans fats, processed meats, and charred or smoked foods. You’ll find that processed foods generally don’t fit in this type of diet as well as fresh foods do.
