Many diets can help you lose weight. However, "going on a diet" is not the best answer to losing weight. Usually you gain the weight back after you "go off" the diet. If you want to lose weight and keep it off, you have to change much more than just what you eat. You have to change how and when you eat, and you have to start exercising or exercise more often. Most people who lose weight and keep it off do 3 things. First, they find out why they are overweight. Second, they follow a healthy eating plan. Third, they exercise regularly.

How does what I eat affect my heart? The food you eat can affect the way blood flows through your heart and arteries. A diet high in fat and cholesterol can gradually cause a buildup (called "plaque") in your arteries. That buildup slows down the blood flow and blocks small arteries. If the blockage happens in an artery that carries blood to the heart muscle, a heart attack can occur. If the blockage happens in an artery that carries blood to the brain, a stroke can occur. The right diet helps keep your arteries clear and reduces the risk of heart problems and stroke
