Flashcards in Energy Balance/ Weight Management Deck (14):
1

RMR

largest component of daily energy expenditure (60-75%)
required to maintain normal body function

2

Diet induced thermogenesis

Increase in energy expenditure after eating
10% of energy

3

Thermic effect of exercise

most variable depends on work

4

Visceral fat

accumulates within abdominal cavity
poses increased risk to health

5

What horomone promotes satiety

Leptin- produced by adipose tissue

6

Waist to hip ratio is a good mortality indicator in what pop

older imdv.

7

Densitometry

Water displacement, based on density of fat and fat free masss

8

DEXA

compartments w/ dif densities absorb dif amounts of low energy x rays

9

Energy expenditure calc

Athlete with 47.3 kg FFM, burns 14kcal a min works out for 60 mins

RMR= 500 + (22* FFM) = 1540
DIT= 1540*.3= 462
TEE= 14kcal/min * 60 mins= 840

10

effects of v low energy diets

rapid weight loss (1st week loss of glycogen/ water)
increases ketosis

11

effects of low fat diet

effective in reducing energy intake/ promote fat loss
fat is stored effectively + requires lil energy for digestion

12

high pro diet

has greater effect on satiety, thermogenic effect

13

low carb diet

ketogenic diet produces ketone bodies that suppress appetite
not recomended

14

@ what percentage VO2 max does most fat oxidation occur

55-65%
