Query: Issues with this book

I bought the items recommended, and ended up having to not use them. I bought suggested items of non preserved coconut and it was the only thing I could eat. Also bought suggested items of coconut cream and coconut oil. Got really sick from trying to do things the way the author recommended. Would not buy again. Just a waste of time and did not loose any weight.
