@machak I was diagnosed with lupus back in 1988, and experience mild flares from time to time. For me, when there is a flare, I just don't feel like eating, no matter what other things may be going on. I do take a steroid dose once a week for another issue, and know that while some people experience a real appetite boost, I don't. Do the steroids give you "energy boosts" that might be counteracting maintaining your weight?
