Here simple and brief explanation of what body mass index (BMI) is and why it matters.
Why use BMI instead of weight?
The same body weight in two persons would be interpreted differently depending on how tall the person is, right? That is why a person is said to be underweight, normal weight, overweight, or obese based not on body weight but on the body mass index (BMI). The BMI is calculated from a person’s height and weight.

Interpretation of BMI (Kg/m²)
< 18.5 — Underweight
18.5 to 24.9 — Normal or healthy weight
25 to 29.9 — Overweight
30 or more — Obese
The category of Obese is subclassified as follows:
30 to 34.9 — Class I obesity
35 to 39.9 — Class II obesity
More than 40 — Class III obesity
