he's saying it takes energy to maintain body temperature and he uses swimmers as a example where their raw exercise seems to account for a third of what they ingest in calories. While yes technically energy in equals energy out, he's saying that the calorie ingested equals calories exercised model specifically can be expanded to include calories the body uses to maintain its core temperature under thermal loading.
My forums posting really doesn't do the book justice.
