My only advice is to try keep to a keto diet as it is something that works for me.
When on keto I have zero interest in anything with sugar in it so problem foods are no longer a problem. It will also have the added benefit of helping you transition into fasting again maybe just do a few 24’s first.
I’m surprise the automod didn’t post it’s “no fasting 2 weeks after vaccine” thing.
Edit: sorry that’s not helpful. allegedly your body does need the extra nutrients to build strong antibodies after the jab. Yada yada I was/am sceptical, but after the post-jab sickness wore off, I was a ravenous beast for a few days after getting mine.And chin up chipmunk! We’ve all been right where you are. Struggling to fast again after a solid streak and beating ourselves up because we feel like a failure. Well you’re not a failure. Give yourself some grace. It’s not a sprint. Fasting burn out is real.
