What do you mean by base 7 dieting? I have never heard of any such diet plan. Where did you come across this concept? There are several different diet plans going around and there is a good chance that something like that exists. If I were you, I would ask around and get some professional advice regarding this. I tried Googling it and I could not find anything that is related to this. I am sorry that I can't be of more help, but I am not an expert on this. I followed a 2 month diet plan and it worked for me. So I never needed to look past that.
