From the way that my chemistry teacher of a long time ago explained it, when you are studying intensively, your body uses A LOT of resources to power the brain (many more than they normally do). That's why sugar is a necessity while studying; it's the most effective way to retain focus.
As far as the lack of weight loss goes, did you change your diet at all or did you remain the same? I know when I was doing 125 - 150+ mile weeks consistently, I lost a ton of weight, but when winter showed up, I reduced the amount of cals in my diet (less than 2000 daily, I think) and did light calisthenics and my weight actually continued to decrease. I don't even know where I am, but I would have to say that I gained very little, if anything.
