[maximus-decimus]

A body temperature increase... as in a fever? If eating food gives you a fever, you have bigger issues than losing weight.

The problem with saying everything goes to fat if you eat 1200 calories in 1 shot is that if that happens, you'll actually burn the fat during the day when you need it, and you'll lose energy during the conversion, meaning your body will be overall less efficient than using it straight away and you'll lose even more weight. I don't know how inefficient that really is, all I remember from my biology classes is this is a lot more efficient than burning muscle, but it sure doesn't increase the total amount of energy in your system. That would be breaking thermodynamics laws.

i.e. Just because you store fat, doesn't mean you need any less calories per day. Your body won't just starve itself to death while leaving your fat alone.
