The first time I was on Prednisone I was ravenous all the time but it was right after I had my resection so I had to be extremely careful with what I ate. The second time I made sure I had healthy snacks available and ready to go and then just didn't eat meals. Just took a handful of whatever to curb my appetite. I only gained a few pounds.
I was really surprised just how hungry I got. It was unbelieveable along with the mood swings.
Hint: Never tell your teenage children when you are on pred. During my up swing they talked me into getting a new computer and cell phones for them. I had been telling them no for years. I was such a push-over.
