Being overweight puts you at increased risk for high blood pressure, high cholesterol, and diabetes, all of which increase your risk for CAD. If you're not sure you're at a healthy weight, calculate your body mass index (BMI), which measures your weight in relation to your height. A BMI between 25 and 29. is considered overweight, and 30 and higher is considered obese. A normal BMI is between 18.5 and 24.9. If you need help losing weight, discuss a healthy eating and exercise plan with your doctor.
