I have two weeks vacation coming up and I want to start IF and be finished fat adaptation by the time I return to my construction job, so I’m not all weak at work.
I did IF with a 20:4 window last year, and it took me 3~4 weeks to really adapt.
Many thanks!
I’m not positive- but I think the quickest way to get fat adapted is IF and keto combined. Once you get fat adapted- slowly add back in your carbs. I wish I had the will power to do keto but I just can’t. At least with fasting I eat what I want just at certain times
