Oh IF is just how I have generally lived my life, long before it was "a thing". So not much to compare. I did have a really good experience doing long fasted running in the morning. At first I couldn't go three miles without breakfast. But eventually I could do twelve straight out of bed and feel great. As I understand, fasting trains your body to supply blood glucose from fat stores, which breaks your brain's craving for sugary foods- which are a crutch for getting your blood sugar up. (Remember, your brain runs mainly on blood glucose) Keto does the same thing a different way. But to me IF is way easier and healthier. (I strive to eat a Mediterranean style diet which ain't Keto!) I would say the experience for me is really good- as long as I avoid the cliff, which is what I was warning about. Basically, just don't try to get all extreme thinking longer fasts are always better.
