Most fasts I've ever heard of prior to IF, were called "water" fasts. (I've heard of juice fasting too) Its obvious that the 600 calorie allowance makes the fast much more tolerable, but is that like using training wheels on a bike?
Will my benefits be greater if I eat and drink nothing but water instead of the 600 calories? Since it wasn't that hard, its certainly doable for me, unless there are any glaring reasons why the 600 is superior?
