Question

Approximately what percentage of our total energy output is attributable to the thermic effect of food?

A. up to 10 percent
B. up to 20 percent
C. up to 40 percent
D. up to 60 percent

Answer 1

A. Up to 10 percent.

Step-by-step explanation:

The energy required for all the enzymatic reactions that take place during food digestion and absorption of nutrients is called the “thermic effect of food” and accounts for about 10 percent of total energy expended per day.

Answer 2

Up to 10 percent.

Step-by-step explanation:

Thermic effect of the food may be defined as the amount of the energy expand above the BMR due to the food storage and its processing. The thermic effect of the food can be increased by the aerobic exercises.

The production of the heat by the adipose tissue is also involved in the thermic effect. The estimates used for the food thermic effect is around 10% of the individual's calorie intake and may also depends on the effect of the different food components.

Thus, the answer is up to 10 percent.
