 I agree that often his concern for being efficient and "green" sometimes goes above what makes sense- for instance when at the beginning of the book on page 55 when he is talking about doing vigorous exercise for 5 minutes instead of heating up the rooms in his cottage, and that "a person occupies less than 1 percent of the volume of a room. Why heat more than 99 percent just to heat that little volume?" (56). Yes, perhaps we are smaller than the size of the room, but by jumping around every time he gets cold in his 11 degree C cottage he is using up energy to keep himself and his internal organs warm and functioning. But he is expending energy, so he will have to eat more to maintain that level of energy and fat for warmth storage. And he goes on at length about his appetite and how he needs to watch what foods he has there and must be efficient with what he eats and how much, so he can make it all last. I feel like his logic in the heat reduction plan is counterproductive.
