I too have recently jumped back on the wagon!
IF into EF wasn’t all that bad imo, I can do 48 fairly easily depending on what I ate last, lots of protein and fat vs lots of carbs
My biggest obstacles are my B.E.D., cooking for a family, and the incredibly vivid dreams about food lol
I started IF 4 weeks ago, first 18:6, then 20:4, then OMAD. I am currently 40 hours into my first extended fast (aiming for 5 days) and I am doing great. No headaches, manageable hunger, I think the IF really helped to make this a lot easier.
