IN RESPONSE:
We have reviewed the letter about our article on diet composition. Dr. Citkowitz makes two points in this letter. The first is that we underestimated the importance of the thermic effect of food between a high- and low-fat diet. Unfortunately, Table 1 contained a typographical error. In column 1, the thermic effect of fat should be listed as 10 kcal rather than 90 kcal. Thus, Dr. Citkowitz's argument that the difference in the thermic effect of food between a high- and low-fat diet is substantial is not true. As we state in the text, this difference is small (30 kcal/day).
The second point made by Dr. Citkowitz is that exercise allows a higher caloric intake without weight gain. This is true, but has little to do with the thermic effect of food. This effect is proportional to total energy intake; the higher thermic effect of food accompanying the higher total caloric intake seen with exercise is not likely to be nearly as important in body weight regulation as the increased energy expenditure occurring during the exercise itself.
