If 2500 cals is more than you were eating, and you are feeling better for it, then I'm glad you've increased. I believe you that digestive distress makes eating more difficult. This seems to be a fairly common consequence of undereating and low metabolim (and maybe there are other causes involved too). Here are related thoughts form Gwyneth Olwyn's:

The point of eating more is to provide sufficient energy for the body to restore/(re)build structure and to support optimal functioning - including endocrine functions.
