The BMI has some limitations. BMI does not provide information about a person's percentage of body fat or muscle. However, the BMI is a useful and practical guide to show people that they need to lose weight, and particularly fat. If your BMI is too high, consider a basic plan that includes increasing physical activity and some modest changes in food selection to reduce health risk. Eat a sensible, well balanced diet that includes a variety of foods and plenty of grains, fruits and vegetables.

Once you have medical clearance, increasing your activity can be easy. Here are some guidelines for success. Take it one step at a time.
