I gained 10 pounds when I was on the higher doses of prednisone but I was on the slender side previously so the extra pounds didn't put me in the overweight category by BMI. I'd like to lose the weight now that my dose is lower but I'm not going to worry about it. A little extra food can be comforting when dealing with an uncomfortable disease. I've never followed any particular diet. I have a garden, fruit trees and berry bushes and fresh organic produce nearby and it all tastes good to me. I avoid desserts, soda, snack foods, food additives, fast food and go very easy on meat. The higher prednisone doses made me feel hungry more often and I was used to eating when hungry. I need to slowly break habits I got into now that my prednisone dose is 5.5 mg. Pain keeps me from being as active as I would like but I love being outdoors hiking, biking and birding and do those things as much as I can. In my opinion, a specific diet is not needed to lose weight, just a focus on generally agreed-upon principles of healthy living, and moving away from the typical American diet and activity level as much as possible for each person.
