What is BMI? |
Stands for Body Mass Index - calculates your weight class based on height and mass |

Is BMI perfect? |
No, it does not take into account skeleton size, where the fat is, or muscle mass - one can be in shape, but muscle mass can raise BMI - can't distinguish fat from muscle |
|
|
Brad Pitt BMI example |
He is considered overweight even though he is in shape. This is due to his muscle mass being counted as fat |
|
|
Total Energy expenditure (TEE) |
made up of Basal metabolism + energy spent in movement + thermic effect of digestion of food |
|
|
What percent of energy consumed goes to Basal Metabolic Rate (BMR)? |
About 60% |
|
|
What percent of energy consumed goes to activities involving movement? |
About 40% |
|
|
60% energy expenditure breakdown for BMR |
20% brain - 20% liver - 20% muscle - 10% heart - 5% kidney - 3% adipose - 22% other tissues = 100% of 60% energy expenditure from BMR |
|
|
How can BMR be estimated? |
1 kcal/kg/hr for males 0.9 kcal/kg/hr for females |
|
|
% of TEE from thermic effect of food? |
About 5-10% - the energy used goes towards making digestive enzymes and to transport nutrients |
|
|
How is TEE measured |
oxygen consumption is the most common used |
