How To Get Back In Shape

Body Mass Index (BMI) 

BMI or Body Mass Index compares your weight to your height. It is an indicator of body fat, which in turn is an indicator of your health and your health risks.

Your BMI combined with your waist measurement (WC) gives you a good indication of your body fat and therefore, of your health risks. It is calculated using your height and weight. It is a good measurement to keep track of as you get back in shape.

Click the CDC's BMI calculator to enter you height and weight or use the formula:

BMI = (Weight in Pounds/( Height in inches )x (Height in inches) )x 703

For children or teens, use this BMI calculator for teens.

The Chart below gives you an idea of your weight status and your goal BMI* 

BMI	Weight Status
Below 18.5	Underweight
18.5 – 24.9	Normal
25.0 – 29.9	Overweight
30.0 and Above	Obese1

Classes of Obesity¹:

30 to 34.9 Class I

35 to 39.9 Class II

Over 40 Class III

*Note: The accuracy of the BMI diminishes in very short or in very muscular people and in older people who have muscle wasting. For a truer measure of body composition use skinfold caliper testing.  Also, use your waist circumference (WC) as a health indicator.  While BMI is an important measurement, it should not be used alone.

The Surgeon General explains some consequences of BMI greater than 25, including premature death, diabetes, cancer and heart disease. Risks for diabetes, hypertension and cardiovascular disease increase with increased BMI and waist circumference.
