"Turn Up The Heat" by Dr. Philip Goglia
This is the book I read to learn more about the metabolic types (click the button below for more info).
In it, the author shows how to read your recent lipid panel (cholesterol, etc.) to determine your metabolic type. He also includes an easy quiz in case you don't have recent lab work.
In the reviews, a lot of people mention typos and mistakes. This is true. However, I feel the fundamental information is really good.
I corresponded with the author's customer service team and they told me the meal plans in the book are out of date. I don't use them anyway, I make my own meal plans.
Through following what I learned in this book, I lost nearly 10 pounds in the first month (all in my belly) and I felt a bump in my energy level. I hope this helps! Be sure to let me know if you have any questions! -Wardee
