Oddbean new post about login | logout šš Been very low carb/carnevorish for 4 y now. Led to only having the need to eat usually twice a day and staying lean and fit. Never done any longer fasts than 1 day though š. Tip: Don't forget the electrolytes when fasting longer. Those are lost very quickly with the water in the first couple of days. Headache and tiredness are comon symptoms of low electrolytes. Good luck.
