You didn’t really say why you are fasting? If it’s for weight loss, I would continue the fast and then probably be more careful about my food choices for the day (higher protein) to counteract the sugar bomb that Nutella is.
If it’s to control insulin resilience, metabolic disorder, overall focus, etc, I would probably open my eating window, close it at 4 or 6 hours (whatever your typical eating window is), then fast longer the next day to get back on schedule.
Couple of things:
make your eating window that you opened super small. As I a quick OMAD of a couple of hours. Don’t binge, just have a big healthy meal.
maybe get rid of or hide the things that ‘break’ your fast, like a jar of Nutella. Out of sight, or at the very least you have to make an effort to find it, and your mind will tell you not to.
Do you mean “just go ahead and eat more stuff”? If so, no. Continue as if you didn’t eat the Nutella. I saw a post somewhere about the calories that one piles on when not stopping after taking that first bite of something. Always stuck with me.
I have emptied my house if such things. I don’t have the willpower to avoid them if they are there. Don’t miss them much if they aren’t.
Plus eating good nutritious foods makes IF WAY easier. It really helps with the cravings. I found the first two weeks tough as I was HEAVILY over carbed. Now my body has got with the program it’s way easier.
