Hey, Primal Papa, what I did before I tried this diet was I did a search for stories of failure. On this forum you are mostly going to get stories of success because the failures will just drop off. But even so, there are a few threads I can remember where people claimed this diet failed them and they are interesting to read mostly because those people either had unrealistic weight loss expectations or didn't actually follow this diet or both.
