Flashcards in Skildom: Nutrition, Energy Deck (20):
What is the eqtn for BMI?
Weight (kg) / Height2 (cm)
What if the BMI is <19?
What if the BMI is >25?
How do you quantify metabolism?
What is BMR?
Measured under standardized conditions
What is RMR?
similar to BMR but LESS standardized conditions
What is REE?
Resting Energy expenditure kcal/day (if all you do is sleep and eat)
What is TEE?
Total energy expenditure
What is the eqtn for TEE?
REE plus energy expanded in physical activity, wound repair.
TEE= REE x 1.4 for healthy active adult
What are the three components of human energy expenditure?
EEPA- energy expenditure of physical activity
TEF= thermic effect of food
BMR= basal metabolic rate
What is the gold standard for measuring metabolism?
How is metabolism usually measured?
What does indirect calorimetry measure?
Volume of inspired air and expired air
What is the eqtn for RQ?
volume of CO2 exhaled/ volume of O2 inhaled
What is the least oxidized fuel and how does htis affect indirect calorimetry?
FAT (most reduced)
Requires MORE O2 inhaled for each CO2 exhaled
Describe the oxidation state of protein?
BEtween carbohydrate and fat.
What isthe most oxidized dietary fuel?
Requires LESS O2 inhaled for each O2 exhaled
Rank RQ from lowest to highest for the dietary fuels.
What does an increase in RQ suggest?
