BMI or Body Mass Index is an inexpensive, easy to use tool to determine whether an individual is underweight, normal or overweight.
Based on how tall a person is, a healthy body weight can be estimated. Overweight and obese individuals are generally at greater risk for heart disease, diabetes, dislipidemia and some types of cancers. Differences in body type between ethnic groups have brought out the need for different thresholds for different races.
A waist circumference of more than 90 cm (36 inches) for men and more than 80 cm (32 inches) for women puts them at high risk for diabetes and hypertension.
1m = 100 cm; 1m = 3.28 feet
