BMI (Body Mass Index) is a measurement of body fat based on height and weight that applies to both men and women between the ages of 18 and 65 years.
BMI can be used to indicate if you are overweight, obese, underweight or normal. A healthy BMI score is between 18.5 and 24.9. A score below 18.5 indicates that you may be underweight; a value above 24.9 indicates that you may be overweight.
