I didn't really follow a book. I read The Detox Diet book by Dr. Haas but that was after I had started and it just reinforced what I already knew. I just decided to cut out processed foods and red meat, dairy, sugar, gluten and caffeine because I have issues with yeast and I wanted to detox my liver and kidneys and give my stomach a break and I realized as soon as I did that I felt better.
In my original post I had said that this takes a lot of will power but it doesn't. It actually requires very little. When you cut out foods to lose weight you feel deprived. When you cut out foods to save your life it is pretty easy.
I eat loads of salads and roasted vegetables, some fish, whole grains (quinoa is my fave), beans, lentils, organic chicken, some fruit, and nuts.
My doctor had given me detox ideas(sauna, epsom salt baths, colonics, etc) and told me exercising was imperative.
I ALWAYS feel like hell the week before my period since I have gotten sick and this is the week and, while I don't feel perfect, I am managing this in a way that has me functional and with limited pain.
