What's Your Opinion? IF 24/7 or Do You Allow Cheat Days?

My friend and I are both doing IF. She takes the weekends "off" and eats and drinks whatever. I think this includes sodas and fast food (she is diabetic and can't give up sugar).I am doing 16:8 every day, no cheat days, but will adjust my window. I have a couple vodka sodas on the weekend, pizza on Saturday, but all in my window.I personally feel like a "cheat day" will throw me off, but some literature I read says you essentially need cheat days.So what do you do? Do you have lax days? Are you super strict about your window? I kind of want to get a better idea of what the majority does. via /r/intermittentfasting https://ift.tt/2M5xJ85 https://ift.tt/eA8V8J
