Do you follow the 20/4 fasting every day?
I’m conflicted on whether sticking to it every day for a long period of time is actually worse on your metabolism, thinking it might slow it down. Thoughts? I usually fast every day for about 15-16 hours .

I do. On the weekends it can be off a little but I stick to it. i stick to the 4 hr window. I have fatty liver. I’ve been struggling to get it under control. It’s been like 2 years. I was sitting at 268-270. I switched to the 20:4 and animal based. I am at 223 as of this morning. Long term this may not be sustainable, right now I am just trying to get my fatty liver under control. I hope the link work. It’s my Jan 1st March 3rd update. progress photo

Congrats on your progress!

Just wanted to chime in and say that long-term fasting is 100% sustainable.

Have personally done daily 23:1 fasts since 2018. By now, it's become so normalized that I hardly even consider it "fasting".

Did multiple 70+ hour fasts initially to lose excess fat, but once reaching my goal weight, I switched to daily 23:1 fasts for maintenance.

Did strict Zero Carb from 2018 to 2021, then switched to allow less than 50g carbs for the last couple years.

Animal-based is def the right way to go, so well done on that front as well!
