Depends on weather and what you do in it. Go out on hot day and do bunch of work dry fasting.Its wild card how long you can live without any water. Much more dangerous then water fasting.
Day or two likely ok but really no symptoms in 7 days ???
No weakness, lightheadedness, dark urine ,or other dehydration symptoms? Or did you think those symptoms were detox?
Should I link the dehydration symptoms again?
You are taking in no salt and no carbs nothing on dry fasting.So can't possibly see how you won't be dehyrdated pretty quickly.
But hey whatever as said you guys can believe what you want. Breatharians think they can live on air! LOL
