Has anyone here tried The Body Type Diet?

Barberoni

I tried it several years ago and did well on it. I found that I was a Thyroid type and now I've decided to do it again. But I no longer have a thyroid and I'm taking synthroid for the rest of my life. The diet is high in protein and I've been having pain and discomfort in my side. I think it could be from my kidneys reacting to the protein. Has anyone tried it and what were your results?
