Extract: The effect of energy content and protein concentration of a test meal and exercise intensity on the thermic effect of food (TEF) was examined. TEF was measured in eight men in response to meals representing 15, 30, and 45 per cent of daily energy requirement; protein concentrations of 15, 30, and 45 per cent of energy of the meal, and exercise intensities of 35, 50, and 65 per cent of maximum capacity. In response to energy content of the meals, total 3-h TEF (mean plus or minus SEM) was 4.0 plus or minus 0.83, 9.7 plus or minus 1.15, and 10.8 plus or minus 0.79 1 O2 for the 15, 30, and 45 per cent meals, respectively, indicating a positive linear and a negative quadratic relationship. Although the 15 per cent protein meal resulted in the smallest TEF, 150-270 min after the meal, total 5-h increase in oxygen consumption did not differ among the three protein meals. Exercise intensity did not alter TEF. Energy content of the test meal had the greatest effect on TEF.(author)
