• Take Mass (aka:weight) in lbs Take Mass (aka:weight) in lbs
• Divide by 2.2 (to get kg)Divide by 2.2 (to get kg)– Ex. 140 lbs / 2.2 = 64 kgEx. 140 lbs / 2.2 = 64 kg
• Multiply this # by 0.9 if female; X by 1 if Multiply this # by 0.9 if female; X by 1 if malemale– Ex 64 kg x 0.9 = 57.6 (BMR) – per hourEx 64 kg x 0.9 = 57.6 (BMR) – per hour
• Multiply by 24 hours in a dayMultiply by 24 hours in a day– 57.6 x 24 = 1382.4 kcal per day --- 57.6 x 24 = 1382.4 kcal per day --- JUST TO JUST TO
