I've had Crohn's Disease for 4 yrs now. I am also a medical professional. Please, please wait until at least one year of being free from flare-ups to start Clen or anything else. Much too soon right now. As for the Prednisone, it is certainly NOT the same as anabolic steroids. The weight gain you are experiencing is from the Prednisone and will not be shed with Clen. The weight will dissipate once you discontinue Prednisone, and it will take time. I tapered from 100mg daily and it took 9 months to lose the weight and come off the Prednisone. It is NOT fat. You will lose it...without exercise or calorie restriction. Consume plenty of water. Studies show at this point that Predisone is no more effective in treating IBD than the standard IBD meds combined with antibiotics. I will never use it again. I have cycled Clen (being disease free for over 2 years) without a problem. Keep your diet low in carbs and very high in protein. Supplement with protein shakes/bars in addition to your meals. Please wait until you are healthy, as your large intestine still has significant ulcerations at this point in time. Be well.
