"Your body can't turn into a perpetual motion machine." Has a certain brutal logic to it, doesn't it?
When people are forced to eat below a maintenance level of calories (people in POW camps, contestants on Survivor or The Biggest Loser), they lose weight. It may not be healthy, but the weight loss happens.
Yeah, but it's REALLY unpleasant, your statement completely fails to take that important factor into account.
