Running and shit is your problem. Why do that, your body is forcing you to give it life saving nutrients. GOOD GOD MAN you need twinkies stat!!6 foot 185lbs. What's your best 10 miler?
Just like every animal we must eat. Fasting when you have access to food is retarded. Eat, drink, be merry enjoy life that's what we are here for.Low blood sugar isn't anything to fuck around with. Don't try to fast or go a long time without eating anything and then do physical activity if you experience symptoms like that. When I used to fast for long periods of time, I had a few episodes where I nearly passed out from low blood sugar.
"Untreated, severe low blood sugar can be very dangerous. It can result in seizures, loss of consciousness, or death."
