Stop fasting then. You made it 8 days, that’s incredible and you should actually feel so proud of that!!
Refeed carefully, eat modestly and low carb for a few days or a week, and go at it again
You’re going to put some water weight back on, but that wasn’t weight you lost in the first place. Think of it like a security deposit.
If you can’t take all the electrolytes, you’ll likely have to accept “shorter” fasting durations (7-8 days is still really long).
Magnesium is a laxative in high doses. Probably why you’re having that problem. I would cut it out of the electrolyte stack. But everyone here is right. Listen to your body and stop fasting, you can readjust and fast again later
Have you also been drinking coffee/tea? That can add to the dehydration. I would stop fasting and restart. This is a sign to stop since your body is not getting the proper amount of electrolytes and hydration.
Aw I’m sorry for your experience. Diarrhoea leads to dehydration and fatigue, making the fast that much harder. What’s curious is that your bowels still have waste to eliminate. In a way, I wonder if it’s cleansing?! 🌲🍵
