A couple of months ago I went up to 40hr fasting on only water. I got what they call a keto rash. Upper body all red, warm and itchy. I got scared and devoured high carbs. For context I am used to 18-20 hrs of intermitted fasting. This was my first time stretching it out. Is this normal? What can I do to jump this hurdle?
Appreciate all input Thanks!
I got it once too. It was pretty bad — itchy hives/welts from thighs to face. 3 day fast at that point. Had some buttered toast and it cleared up by morning. Have not had it since. If it ever starts to happen again I will break my fast sooner.
