I'm a big fan of fasting, though it's a new found love for me. I used to be a grazer until I learned more of the science around IF and autophagy. Once I saw the actual benefits first-hand, I was hooked. I fast 18-20 hours a day (last meal around 7...first meal around 2) most days, for a few weeks. But I also believe the body gets used to things and needs a reset so I'll go back to a regular 12 hour overnight fast for about a week. My sleep is better and my energy is higher. My job is very physical right off the bat, at 5 am and I am never low on strength for that.
Having a fasting routine works wonders for me!
