Oh and for what it's worth... I disagree with the comment that the book was not designed to help you lose weight. There is a LOT of info in there regarding that very issue, and on the website as well.
Also I agree with BOB about how it "hits you on the nose." I could not believe how "right on" some of the info was for me... which gave me an encouragement to try what they say... because it is RIGHT about a lot of stuff in my case.
Oh... and RH negative makes no difference... I am negative too so checked that out.
Time will tell...
I will keep you posted on how it goes for me.
