When you eat, your body converts any calories it doesn't need right away into triglycerides. The triglycerides are stored in your fat cells. If you regularly eat more calories than you burn, you may have high triglycerides. The higher your triglycerides, the higher your risk of heart disease. The solution? Healthier habits. Choose healthy foods, such as fruits and vegetables. Scale back your portion sizes. Include physical activity in your daily routine.
