Anyone else here with Crohn's disease trying to lose weight?

Hi there my fellow MFPers! I was diagnosed with Crohn's in 2006 when I was 15. I was only 98 pounds then. After being on a slew on medications and getting healthy I have gained a lot of weight. I was 160 pounds when I started my journey. I am about 145 pounds now. I would like to lose about 20 more pounds. I am 5'5" and 22 years old. I just upped my calories to 1600. I was at 1200. I do exercise regularly and try to eat healthy. It's hard though because there are a lot of foods I cannot eat. So, just wondering if there's anyone else on here who has Crohn's disease or any other tummy issues?
