Hi Musika,
My sister PoofieD does both a bit of Atkins, and SP. She sees the benefit of both, so you might do well to check out her journal. I see no qualms in eating the best you can, I think that is the great thing with SP, I don't think fast weight loss is the answer but that is what most people look for, it is the slow and steady that stays off, and when you focus on health it can only improve.
