The body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m 2, resulting from mass in kilograms and height in metres.
The third BMI category is overweight. The overweight category is for men who have a BMI of 25.5 to 29.9 and women who have a BMI of 25-29.9. This is where the BMI numbers for men and women start to reach the same point. Being overweight increases the risk of high blood pressure, heart disease, and many types of cancer.he next BMI category is normal. A normal weight is not the weight of your favorite actor or your best friend. A normal weight is determined by your gender and height. That is why BMI is a good starting point. For men a BMI of 23-25 is normal. For women a BMI of 19.1 to 24.5 is normal.
