1

What is the eqtn for BMI?

Weight (kg) / Height2 (cm)

2

What if the BMI is <19?

underweight

3

What if the BMI is >25?

Overweight

4

How do you quantify metabolism?

BMR
RMR
REE
TEE

5

What is BMR?

Kcal/day

Measured under standardized conditions

6

What is RMR?

Kcal/unit time

similar to BMR but LESS standardized conditions

7

What is REE?

Resting Energy expenditure kcal/day (if all you do is sleep and eat)

8

What is TEE?

Total energy expenditure
kcal/day

9

What is the eqtn for TEE?

REE plus energy expanded in physical activity, wound repair.

TEE= REE x 1.4 for healthy active adult

10

What are the three components of human energy expenditure?

EEPA- energy expenditure of physical activity
TEF= thermic effect of food
BMR= basal metabolic rate

11

What is the gold standard for measuring metabolism?

Direct calorimetry

12

How is metabolism usually measured?

Indirect calorimetry

13

What does indirect calorimetry measure?

Volume of inspired air and expired air

14

What is the eqtn for RQ?

volume of CO2 exhaled/ volume of O2 inhaled

15

What is the least oxidized fuel and how does htis affect indirect calorimetry?

FAT (most reduced)

Requires MORE O2 inhaled for each CO2 exhaled

16

Describe the oxidation state of protein?

BEtween carbohydrate and fat.

17

What isthe most oxidized dietary fuel?

Carbohydrates

Requires LESS O2 inhaled for each O2 exhaled

18

Rank RQ from lowest to highest for the dietary fuels.

Fat< Carb

19

What does an increase in RQ suggest?

Hyperventilation
overfeeding
acidosis

20

What does a decrease in RQ suggest?

Hypoventilation
Underfeeding
Alkalosis
Ketosis
Ethanol
