Success Losing Weight On The Paleo Diet

Below is a recent success story from a paleo follower:

Dear Dr. Cordain,

My name is Chase. I am writing this to thank you for your work on The Paleo Diet. I have only been on the diet for 12 days, and already have had success that I have never had on any diet or fitness program I have ever done.
I have struggled with weight since childhood, however I got it mostly under control by my last year of college. But within a year and a half of starting my career, I was gaining once again. However, through much effort and trial and error, I returned close to what I wanted to weigh and maintained that until a few months ago. I had heard of The Paleo Diet, but did not fully research it. However, after a very busy very unhealthy week of fast food, alcohol, and every unhealthy food that I could eat, I had some downtime on a Sunday and someone close to me asked me if I had heard of this diet because they were thinking about it. In researching it for them, I gained interest while they lost it, and resolved to start it and stick with it. That was the day before I started.
I have exercised vigorously for four years prior to this diet. However I could never get past 183 lbs. Within a week of reading your book and starting the diet, I broke that number, am the lowest I have weighed in five years, and recently recorded a body fat percentage of 9.8%, the lowest I have ever recorded. I have increased energy and am actually exercising less now than I have in months.
I’ve read your book daily as my guide. Without your assistance through this work I do not think I could have achieved this success. Thank you for your efforts in this field of study. If anyone asks me about this diet, I will refer them to this book as the best way to understand The Paleo Diet, and succeed at it.

Respectfully Yours,

Chase
