How Much Food Do I Need?? Basal Metabolism is energy used at rest Basal Metabolism is energy used at rest Basal Metabolic Rate (BMR) is calculated using your current weight Basal Metabolic Rate (BMR) is calculated using your current weight

Basal Metabolic Rate 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 kg Multiply this # by 0.9 if female; X by 1 if male Multiply this # by 0.9 if female; X by 1 if male –Ex 64 kg x 0.9 = 57.6 (BMR) – per hour Multiply by 24 hours in a day Multiply by 24 hours in a day –57.6 x 24 = kcal per day --- JUST TO STAY ALIVE

For Example… Brianna’s BMR is 53 Brianna’s BMR is Kcal/Hr x 24 Hr = 1272 Kcal per day for NO Activity! 53 Kcal/Hr x 24 Hr = 1272 Kcal per day for NO Activity! She leads a sedentary lifestyle thus she adds an extra 20% onto her BMR She leads a sedentary lifestyle thus she adds an extra 20% onto her BMR 1272 x 1.20 = Kcal 1272 x 1.20 = Kcal

What About if I Exercise? Voluntary Activities require energy & thus food! Voluntary Activities require energy & thus food! Sedentary (x 1.2) Sedentary (x 1.2) Light activities (x 1.3) Light activities (x 1.3) Moderately active (x 1.4) Moderately active (x 1.4) Vigorous activities (x 1.5) Vigorous activities (x 1.5) Calculate the following Kcal requirements: Calculate the following Kcal requirements: –John weighs 185 lbs.
