Helio: > Sorry for this(other) stupid question, but what's "The Zone" supposed to >mean!?!?!? A concept? I know you are from Brazil, so you have never heard of it. "The Zone", by B. Sears, is a 1000000-copy best-seller. It consists of eating 40% carbohydrates (mainly low glycemic-index), 30% protein and 30% fat (monounsaturate mainly). The %s refer to calories. Eating that way controls insulin levels, and, as claimed by Sears, optimizes the production of "good" eicosanoids. That barbaric term refers to kind of "local" hormone-like substances, which control blood clotting, immune system, pain, etc. It is claimed that, by eating 40/30/30, you can reach a state of perfect wellness ("the zone"). See http://www.eicotech.com/home.nsf/frameset?open and click on "What is the Zone?" > Also Jean-Louis , I could not understand how can you stay a month away >off a shampoo and your hair look clean? Nice shape either? The last time I used shampoo was in May 1997; since then, I wash my hair with clear water only. Before, I "needed" shampoo every 2-3 days (like you). When I stopped it, my hair of course became very greasy. I washed it 3 times/week with water only, but of course it didn't really help to get rid of the oils; however, after 1 or 2 months, the oils started to re-equilibrate, and now I hardly need any hair washing. I do it about once a month, but it's really by habit, because they are not greasy at all and don't seem dirty nor smelly. I realize doing that is not easy (unpleasant during the transition period). A good step seems to use the mildest shampoo, not to use too much of it, and keep your hair short (no problem if you are a man). I think that the sebum is a natural secretion whose purpose is to protect your scalp. The body is not "stupid": if you remove that protection, it will produce sebum at a faster rate. But if you don't, it will produce just the right amount (at least if your nutrition is correct). Best wishes, Jean-Louis [log in to unmask]
