Well for me zero appetite is a signal, I will start missing nights of sleep. I've also noticed that my body literally will be vibrating, my hands and legs move much faster causing much clumsiness. My co-ordination is also effected negatively.

And another thing I notice, although maybe not really "health" behavior is that I stutter, and my speech gets rearranged, and a different rhythm, different word choices than normal.

I'm not gonna say too much about your eating, because I'm with you there. Try to get in a bit more calories than you are burning off, if your fairly active or exercising..

Since you mentioned live foods in my thread, I remembered something I saw the other day ...'live lettuce' at the market. Ever see it or have it?
