Answer 1

1. If Sarah has a total energy expenditure of 2000 kcals per day. If her RMR is 1440 and the physical activity she performed for the day is 422 kcals, what is the thermic effect of food for the day?

a. 142

b. 138

c. 128

d. 146

ANSWER- Total energy expenditure=metabolic rate+physical activity expenditure+thermic effect of ingestion

Therfore- 2000=1440+422+X

X=2000-(1440+422)

X=138

therefore The thermic effect of the body for the day is 138.
