Question

Kristin requires 1,500 calories for basal metabolism and 750 calories for physical activity daily.How many calories does she require for dietary thermogenesis?​

Quizplus · Accepted Answer

Dietary thermogenesis is the energy used to digest food and absorb nutrients. It typically accounts for 10% of total daily energy expenditure.

Total daily energy expenditure = basal metabolism + physical activity + dietary thermogenesis

Total daily energy expenditure = 1,500 + 750 + (0.1)(2,250)  (since 10% of total daily energy expenditure is dietary thermogenesis)

Total daily energy expenditure = 3,150

Dietary thermogenesis = (0.1)(2,250) = 225 calories.

Therefore, the answer is B, 225.
