Hello @dsm68, Welcome to Connect. Keeping the weight off can be difficult when you have PMR and are on prednisone. My first time with PMR I struggled and gained around 40 pounds. After my PMR was in remission I was able to get the weight under control and then six years later the PMR came out of remission. I was determined not to gain the weight back and was able to keep the weight gain around 5 pounds through eliminating processed foods, exercising more and limiting my sugar intake with the sweets.
