Past the two day mark into the fast -- no, I don't feel hungry at all; in fact, food (thinking, smelling, looking it) ranges from "meh" to slight aversion at those times. The reason I fasted the first time, was that I was a little sick, and lost my appetite; this is common. What is uncommon with me, however, is that when I have no appetite, I don't eat. And despite feeling excellent starting with day 3 or so, appetite only came back after more than three weeks. Other times, I started on purpose; on those times, the first two days are sometimes a little hard (but not really). Whether it is good or bad for you - I suggest you try. It is unlikely to be harmful, and it might teach you something you don't know. Or, it might be a waste of time. I wasn't generally sick or anything, but I did have low B12 before my first fast; And I have perfect B12 since. At the time it was a complete mystery to myself and any doctor I've asked, but since it was discovered that the appendix is a vault of good bacteria, and it is likely that fasting caused to body to release some B12-converting bacteria. YMMV, especially if you have no appendix.
