IME eating keto makes fasting easier because keto has a hunger suppression element. Also, you won’t be pulling yourself in and out of ketosis, because you’ll always be in ketosis if you keep your refeed carbs low.
If you can do it, try it! The coolest part is you get to see how you feel and do with this and can make changes to tweak as you learn what you respond best to. But lots of people have really good inflammation response to keto and feel good while doing it. Also limits junk food options, which is never a bad thing!
