weight gain with Celiac Help please

Hi I am new with knowing that I have Celiac(have had it for almost a year before they realized whats wrong) and I was reading on your site about weight lose. That is not my case. I keep gaining weight. I have done a bowel cleanse and a parasite. I workout almost everyday and eat heathly, well because there is no such thing as cheesebread anymore,lol. Is there anything that you can suggest or maybe there is something else wrong aswell(was checked for b12, thyrod etc) Need help please. Laurie Tweet
