What kind of meds are you on?
I was on that oral prednisone for 2 wks and gained 9 lbs. I've cut out snacks and eat 4 times per day, small meals, for the most part. And I've lost 13.5 lbs so far. Sometimes I cheat, but I also work out as many days as I can.
Good luck...I know I hate it when I gain weight.
