I am aiming to do a fast for 7 days. I don't plan to do anything overly strenuous but plan to spend most of my time outdoors, hiking, camping, etc. Unlike most of you I presume, I live in a place were its pretty much summer already (minus the rain), i.e. Florida. That said, I am fairly accustomed to this place. I mountain bike, run, etc in the middle the hottest part of the day every weekend for hours at a time. Also, I don't generally consume much (extra) sodium, but haven't been super paleo lately either (lets say 50%).
I am mostly concerned about electrolytes because of the amount of sweating that I know will ensue. However, I have been reading that your body tends to down-regulate the amount of electrolytes lost in sweat when you are fasting.
So, assuming I am already adapted to the heat here, I have been having slightly higher than optimal sodium intake, slightly lower than optimal intake of other electrolytes, and plan to start a 7 day fast in 7 days from now and spend most of my time outdoors doing light but constant activity (in 80-90 degree humid weather), what special considerations should I take into account and what can I do to best prepare myself in the coming week (besides just eating 100% paleo)?
