About BMI

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple way to categorize individuals as underweight, normal weight, overweight, or obese.

BMI Categories (WHO Classification)

BMI Range	Category	Health Risk
Below 18.5	Underweight	Possible nutritional deficiency and osteoporosis
18.5 - 24.9	Normal weight	Low risk (healthy range)
25.0 - 29.9	Overweight	Moderate risk of developing heart disease, high blood pressure, stroke, diabetes
30.0 and above	Obese	High risk of developing heart disease, high blood pressure, stroke, diabetes

Limitations of BMI

While BMI is a useful screening tool, it has limitations:

Doesn't directly measure body fat
May overestimate body fat in athletes with high muscle mass
May underestimate body fat in older adults who have lost muscle mass
Doesn't account for differences in body composition between ethnic groups

For a more comprehensive health assessment, consult with a healthcare professional who can evaluate additional factors like waist circumference, diet, physical activity, and family history.
