What is BMI (Body Mass Index)?
BMI (Body Mass Index) is a widely used measurement that compares your weight to your height. It helps determine whether you are underweight, normal weight, overweight, or obese.
Although BMI does not directly measure body fat, it is a helpful indicator of general health.
BMI Categories:
- Under 18.5 → Underweight
- 18.5 – 24.9 → Normal weight
- 25 – 29.9 → Overweight
- 30+ → Obese
What is Body Fat Percentage?
Body fat percentage shows how much of your body is made up of fat compared to muscle, bones, and water.
Unlike BMI, body fat percentage gives a more accurate picture of fitness, especially for athletes and active individuals.
- Lower body fat = leaner, more muscular body
- Higher body fat = more fat stored in the body
