I have only a very little idea what it's about, as I haven't bought the book. I was hoping someone else had, and could tell me whether or not it was worth it. It seems to be some sort of nutrional therapy (ie, what to eat and what not to eat).
I've personally found that my diet has a huge impact on my acne (I know all the dermatologists and experts say it doesnt', but for me it does -- it's too great an effect to discount -- I managed to cure cystic acne by changing my diet, and whenever I've slipped, the acne would come back), which is why I was interested in his book -- I've found some things out for myself, but I thought if this guy had any other answers, I'd like to know!
But as you say, it could very well just be a scam. If it was really that easy... you'd think someone else would have published it for free somewhere on the internet... |
