Sorry but the amount of calories the body is capable of conserving by lowering temperature and cell proliferation is not as significant as you think. Also the fact that there are processes to conserve energy says nothing about the level of caloric restriction necessary to achieve these conservation measures. It's far from widely accepted. If the body was able to go into 'starvation mode' and run more and more efficiently, famine wouldn't be such an issue. The fact that you think a western woman with a large caloric deficit is enough to engage some kind of magical 'starvation mode' laughable.
