Good question Jess. I have been wanting to post about this issue as well. I participate in a research study for AS, and every 6 weeks when I go in they do the usual weigh in. In under a year I have found that I have lost nearly 10 pounds without any effort on my part. My metablolism does burn the calories quick, and I can lose weight just by missing a meal. It is becoming a concern of mine because I am about 15 pounds under what my normal body weight should be.
I have also heard that this weight loss is a symptom of the AS too, but no matter how much I eat I can not keep the weight on.
