I have done a few 24 hour fasts with no special supplementation. I’m thinking of trying 36 hours soon. What is the length of fast where electrolyte supplementation becomes necessary? Also, when does gradual refeeding become necessary? Thanks!
You wanna start your electrolytes at the beginning of your fast. You don’t want to wait til your already feeling like crap to do it. Normally on short fasts like 24 or less I don’t worry. Normally I don’t worry til after 48 hours.
