Will I loose my weight again?

So like, I like all week on 800kcal but Saturday O have a cheat day. So yesterday I made cake and brownies and I ate sooooooo much that at one point I was sich but it was soooo good. So before that my weight was 53.5 kg now it's Sunday evening ant I'm 55.7kg. So if I eat 800kcal again, will I weight 53 again tomorrow or the day after tomorrow?
