I'm not a breakfast eater so sometimes I'll legitimately go until lunch or dinner before I get to have food. If I realize I'm already doing it, I'll push myself to fast for longer, since I'm already doing it and whatnot. The word breakfast literally means to break your fast. Sleeping counts as fasting (unless you're an obeast and wake up at 3 am to stuff your maw) so by delaying your first meal, you're continuing the fast you started the night before! P.S. I'm a healthy individual without any food disorders, hope I didn't make my occasional fasting sound like one!
