Calculate Your Basal Metabolic Rate!

Basal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting).

The release of energy in this state is sufficient only for the functioning of the vital organs, such as the heart, lungs, brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin. BMR decreases with age and with the loss of lean body mass. Increasing muscle mass increases BMR.

Increasing Muscle Mass Increases BMR.

This cant be right, at this rate I should be nothing but pure muscle mass considering I usually only eat about 2500 cal a day.

I agree - I con't think this is accurate either - I should be a skinny rail. I consume 1200 calories a day my workout and this site calculates my BMR at 1473 calories a day...hmmm

So I need to intake about 3,500 calories a day... This should be interesting. Well, lets let the mass building begin.

after finding your BMR you need to multiply it by your activity level (PAL)

It says my bmr is 1901 kcal's a day? Is that 1901 calories a day? Who rests and burns almost 2000 calories a day??? I'm 5'11" 175lbs and 24 years old. Do cardio everyday with weight training and eat less than 2000 calories a day according to this I should be shredded!!

I am eating almost double that right now while I am training and my BF% is going down. So is this calculator just for the average everyday life?
