Body Mass Index (BMI) is a screening tool used to categorize weight relative to height. While not perfect, it provides a quick health indicator.

Step-by-Step Guide

Measure your weight in kilograms or pounds
Measure your height in meters or inches
Metric: BMI = weight (kg) / height (m)^2
Imperial: BMI = 703 x weight (lbs) / height (in)^2
Categories: Under 18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, 30+ obese

BMI does not distinguish muscle from fat. Muscular individuals may score high without being unhealthy.

A BMI between 18.5 and 24.9 is considered healthy for most adults.

Children use percentile-based charts, not adult categories.
