Your Basal Metabolic Rate (BMR)
Your basal metabolic rate is important when planning a weight loss program. It shows the rate your body burns calories just for basic metabolic functions, i.e. how many calories would you burn for a day if you just lie in bed. "Lying in bed" isn't very exact of course, because if you are thinking or having conversation while in bed, your body will still burn more calories than your BMR. The BMR shows just the minimum calories required to stay alive.

Your BMR depends on your gender, you age, height and weight. A basic formula for calculation is as follows:

- If your BMI is under 18.5 you are underweight.
- Values between 18.6 and 24.9 are normal.
- Values between 25 and 29.9 show you are overweight.
- If your BMI is 30 or higher your weight is obese.

For males BMR equals 66 + 6.3 multiplied by your weight in pounds + 12.9 multiplied by your height in inches - 6.8 multiplied by your age (because BMR goes down as you get older).

For females BMR equals 655 + 4.3 multiplied by your weight in lbs + 4.7 multiplied by your height in inches - 4.7 multiplied by your age.

Your daily BMR plus the calories you burn for sport and other activities make the total number of calories you burn per day. This is precisely why BMR is so important - it helps you plan a weight loss
