The body mass index (BMI), or Quetelet index, is a statistical measurement which compares a person's weight and height. Though it does not actually measure the percentage of body fat, it is a useful tool to estimate a healthy body weight based on how tall a person is. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to identify weight problem within a population including: underweight, overweight and obesity.

How many calories per day you need?

This adult daily calories calculator gives an approximation of your basal metabolic rate - the number of calories per day your body burns.
If your goal is to lose weight by burning off excess body fat, aim to eat 500 fewer calories per day than your daily caloric needs, and maintain or increase your exercise activity.
Do not go below 1200 calories per day unless you are on a medically supervised weight loss program or after consultation with your doctor.
