(2) That doesn't happen. All throughout history, when prisoners of war aren't given enough to eat, they always lose weight as a result. Starvation mode is a popular diet myth, but it's a myth. It's true that as you lose weight, you need fewer calories to maintain fewer pounds. But that's a different thing than saying your body just prefers having extra weight and will maintain it without resources.
Yes and no. It is true that calorie reduction can cause a slowing of the metabolic rate. The mechanism for that seems to be a decreased activity level which naturally happens during calorie restriction. However if activity level is maintained, as in the OP, then the metabolic rate does not slow:
when people significantly reduce their calorie intake, they undergo a metabolic adaptation that results in a slower metabolic rate. The slower metabolic rate results in a behavioral adaptation in which individuals become less physically active.
