You need a "real world" way of deciding if your weight is right for you. BMI is an objective measure that can help you do just that! BMI is calculated from your height and weight. Doctors often use BMI as an objective indicator to tell if a person is overweight, underweight or at a healthy weight. BMI is recommended by the National Institutes of Health.

It does not take all possible factors into account in its assessment of your healthy weight. For example, it tends to overestimate body fat in very muscular individuals or in people who are less than 5 feet tall, and may underestimate body fat in people who have lost muscle mass, such as the elderly.
