What is BMI and How is it Calculated?

Body mass index (BMI) refers to relative weight for height for both adult men and women and is used as a measuring tool for future disease risk.
A BMI of 30 or higher is linked to increased risks for heart disease, diabetes, high blood pressure, stroke, and arthritis. A high BMI, however, may not be a risk if it’s due to high muscle mass, which is common in bodybuilders.
A high BMI for women increases the risk for serious pre-cancerous polyps or cancer found during their colonoscopies. Obese women are at especially high risk.

The following are the BMI Categories:

Underweight = < 18.5
Normal weight = 18.5-24.9
Overweight = 25-29.9
Obesity = BMI of 30 or greater

Higher BMI is Common in Body Builders
