This is a great book, it will give you a neat understanding of how your brain and body interacts with your daily habits and consumptions. The main topic of this book is the way neurotransmitters function and how you are able to control your serotonin and dopamine levels by following nutrition, exercise and sleep guidelines. From this book you should be able to take control of your energy levels, moods and performance.
Although it is very accurate and informational book, one should take into consideration that it is written by a Doctor. For this reason it will be a very textbook, scientific type of book for which you should take notes, highlight and maybe read more than once.
I will say that even though it is not an very exciting book, it can definitely be a life changing and mind blowing book.
