Is it ok to switch up eating windows?

I'm a big breakfast person. So my eating window is 8 a.m. to noon (doing 20-4). But, I have an important work dinner coming up this Friday. How do you deal with having to change eating windows? Do I just not eat Friday morning and have a 30-ish hour fast before my Friday night dinner? Or, would you just cheat? I'm getting married in January and want to lose 8 lbs by then. I've made good progress so far but the thought of a cheat day feels like I'll fail at meeting my wedding weight goal. via /r/intermittentfasting https://ift.tt/7ISkX4d https://ift.tt/lSnMacf
