What is BMI?

BMI stands for Body Mass Index. It is a measurement that compares your weight and height and is often used as a simple way to identify obesity. BMI is defined as your body weight (kg) divided by the square of your height (m).

Generally, a BMI below 18.5 suggests that you are underweight, while a BMI of 18.5 to 25 indicates optimal weight. A BMI above 25 may indicate that you are overweight. A value above 30 tends to suggest obesity.

What is BMR?

BMR stands for Basal Metabolic Rate. It is an estimate of the number of calories you would burn if you were to do nothing but rest for 24 hours. This represents the minimum amount of energy required to keep your body functioning.

Your BMR depends upon your age, height, weight, and sex. As you grow older, shorter, and lose weight, your BMR goes down. This means that your body requires less energy and hence you will need to eat less and/or exercise more in order to maintain your weight.
