Info on BMI
When calculating a person's body mass index (BMI), two pieces of information are required: height and weight. This is an inexpensive and easy-to-use screening method for weight categories that can lead to health problems such as diabetes, stroke, and heart disease. A normal BMI ranges from 18.5 to 24.9. Anything from 25.5 to 29.9 is overweight, and a reading of 30.0 and higher is considered obese.
However, just because a person has a "high" BMI, this does not necessarily mean that he or she is overweight. BMI is just one factor used to assess a person's weight. According to recent guidelines, assessment of weight involves three key measures:
- Waist circumference
- Risk factors for diseases and conditions associated with obesity.
