Body Mass Index and healthy weight range.
Body Mass Index (BMI) is a simple screening number that relates your weight to your height. It is widely used to place adults into underweight, normal, overweight and obese categories and to flag possible weight-related health risk.
BMI is quick and needs only height and weight, but it does not distinguish muscle from fat, so very muscular people can score high while still being lean.
Categories: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30+ obese.
It works reasonably for the general adult population but is misleading for very muscular people, pregnant women, children and the elderly.
A BMI of 18.5 to 24.9 is classed as a healthy weight for most adults.
No. Combine it with waist measurement, body-fat percentage and how you feel and function for a fuller picture.
