Is it much harder to fast when you are not zero carb first?

I have fasted in the past for up to 96 hours quite happily but I was zero carb back then so my body was always in ketosis. I have since returned to a diet that is more Mediterranean, definitely not ketogenic, definitely not zero carb. I want to try another fast. I have always believed that being in ketosis made fasts much easier. Is that actually true?
