Hey BBBDon’t be discouraged and consider CICO. You got this. It will come even if it takes longer this time.
Do you have a routine for IF and how long have you been practicing IF?I ask since I experimented with a few different types and a 20&4 works best for me and 16&8 didn’t do much. Extended fasts were incredibly transformative but I find I can’t sleep.
What do you drink in a day? Easiest way to break a fast is an unexpected insulin spike if you have some juice or add a little sugar to your coffee.
Do you exercise?
You mentioned Jason Fung have you read his book the complete guide to fasting? It’s a great reference. He also says to give yourself 1 month.
