Hi and welcome to our group. I know how hard it is to deal with the moon face. I've had lupus for 25 years now and I've been on steroids daily for almost 12 years now.
I, like you, have a very very round moon face, stretch marks everywhere, a hump on my back, a patch of fat on the side of my neck, and very round and big in the middle of my body, but I've got these really skinny legs and feet and no butt at all. The family calls me chicken legs I'm currently having problems keeping my underwear and pants up
I stand up to walk and they start to fall down. My daughter finds it quite funny
Like Lynnwood and Joy said you need to avoid sugars and carbs. If you're a soda drinker you need to give that up, it's amazing how many calories are in a soda. They are the big cravings that people get when on steroids. I believe you said that you're still on steroids, you'll just have to give it time. Your moon face will go down eventually, I know that's that quick enough at 16. Try to exercise only once a day and IF your Dr approves it increase the amount of time you work out each day.
Good luck with your diet and we're here to answer any questions you may have.
