Actually, I am currently on this program. I am going to do Step 4 anytime by this weekend. I actally modify my diet from this program's diet. I am going to follow new diet plan which is similiar to diet of non-industrialized people that Weston A. Price had studied in. Diet high in animal fats and meat, low in carbohydrates. I have noticed my digestion has improved much better on this diet. Hmm. I am continuing to experiment with this diet to see how it goes for me. I need to supply more into this diet like finding raw dairy.
