Simply the amount you burn throughout an average day of your life (sans exercise). This next exercise is going to tell us how many calories you are burning in a day without adding in your exercise burn. Men: BMR = 66 + (6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in years )Īfter you have run through these simple calculations and come up with your BMR, we need to then calculate your AMR. Women: BMR = 655 + (4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years ) Use the following BMR Formula for gender to calculate your BMR:
One additional caveat, for the very muscular the calorie burn will be slightly underestimated and for those with a higher percentage of body fat the calorie burn will be slightly over estimated. Barring a hormonal disorder, however, this equation will be fairly accurate overall. If you have hypothyroid, PCOS, insulin resistance, estrogen dominance, there is no way for the BMR formula to read that – you need blood work and an endocrinologist when dealing with these issues. The only factors it omits are lean body mass (the ratio of muscle-to-fat a body has) and biochemistry. The BMR formula uses the variables of height, weight, age and gender to calculate your body’s energy expenditure. That’s your AMR or active metabolic rate. It does not take into account the amount of calories you’ll burn from your daily activity, though. Your basal metabolic rate refers to the amount of calories your body uses for involuntary bodily functions – basically when you are asleep or at rest. In order to figure this out, the first thing we need to do is calculate your BMR or Basal Metabolic Rate.
For this reason, knowing how many calories you burn in a day is critical information when it comes to achieving your health goals. Contrary to the current trend, calories DO matter when it comes to weight loss, weight gain, and weight maintenance.
