I think it’s all so personal, and a lot of it is listening to your body I know Matt has worked one-on-one with people in more difficult situations, so that’s always an option if you continue to have issues. Hopefully the exercise will do the trick.
I happen to think that TV is pretty fattening, so I would imagine you are right about your weight gain there. A lot of people give up exercise during initial refeeding, as the body heals itself, but ideally that extra time is spent on things like sleep rather than TV.
