question4. Which of the following statements describes the thermic effect of foods (TEF)? a. A meal eaten all at once has a lower TEF than one spread out over hours. b. TEF must be considered when estimating energy expenditure because its contribution to total energy output is substantial. c. TEF plus an increase in the metabolic rate due to overeating is called diet-induced thermogenesis (DIT). d. TEF is higher for high-fat foods than for high-carbohydrate foods. e. TEF is estimated...
