1. (i) Basal metabolic energy

70 × (W) 0.75. where W is the weight(kg) of an individual.

FOR ONLINE READING ONLY
70 × (70) 0.75
1694kcal
(ii) Specific dynamic action of food

SDE = 10% (BM+TECA)

10% (1694 +3,318.87)

501.287kcal
(iii) Total energy expenditure

TEE = Basal Metabolism + Total energy cost for
activities + Specific dynamic effect

1694kcal + 3,318.87kcal + 501.287kcal = 5514.157
~5514kcal.

2. Comparison of energy intake and expenditure
Energy from protein
1g of protein = 4kcal
