This is a body weight that is appropriate for your height and benefits your health. One tool to help you determine if you are underweight, at a healthy weight, overweight, or obese is the Body Mass Index or BMI. The BMI is a measure of weight for height for adults over 20 years old. To find out if your weight is in the healthy range, use the BMI chart, which is referenced in the US Dietary Guidelines for Americans.
