Sounds exactly like what Matt says will happen until the body is comfortable that its needs are being met and then things shift. I also felt worse initially, but then the weight started shifting from belly to muscle. My advice would be: relax, don’t overthink it, eat what you crave, go for walks, and do a little strength training. Also, I’d hazard a guess that the girl in that photo spends most of her day eating and working out to put away that many calories and have that much muscle.
