Yesterday I received the 21 day book in the mail and I have to say I am impressed.I could not put it down last night and the information in there really broke down things I had questions about and I have to believe I know finally understand why I have struggled with my weight since my teens. I have not weighed under 200 pounds since I was 19 and I will be 44 years old this year.For such a long time I had to gut feeling that a lot of the the health problems one gets at they grow older is from a combination of weight gain brought on by the average american diet. Reading the book last night may that clear and that the desire to be lean has now become my main goal. Thank you for writing this book Mark
