What Is BMI?
BMI stands for Body Mass Index and is calculated from your height and weight. It is an alternative to a direct measurement of body fat, such as underwater weighing. One size does not fit all, though. Other factors such as body build, age and ethnicity are not considered in this equation.
You can calculate your BMI with this formula: [weight (in pounds) / height (in inches) squared] x 703 or use our BMI calculator.
The Centers for Disease Control and Prevention uses BMI to define terms like overweight and obese:
- Underweight: BMI below 18.5
- Normal weight: 18.5 to 24.9
- Overweight: 25.0 to 29.9
- Obese: 30.0 and above.
To figure out your BMI and find a nutrition plan that works for you, consult a registered dietitian in your area and check out our Understanding Body Mass Index page.
