"In this straightforward, eye-opening guide to eating healthy, Fast offers an informative and honest exploration of rising obesity rates—and what can be done about it.... Obesity is a no-nonsense exploration into food, health, and the human relationship with it. Obesity showcases steps to becoming healthy through eating high-nutrient foods and changing the way one views what one eats. This is a helpful guide for anyone in need of a health overhaul or those interested in well-researched food studies and how it pertains to weight gain." (BookLife Reviews)

"Writing with a thriller’s 'what happens next' flair, Fast pulls in the reader, starting with the first packaged breakfast cereals, which replaced the eggs/bacon/porridge of decades ago. Avoiding a dry recitation of medical studies, Fast makes his point with easy-to-understand research and anecdotes. Attractively illustrated and clearly expressed, the author builds to an indictment of processed foods and the Big Food industry." (BlueInk Review)

"...it is true that there are no perfect books and that weight loss as a concept is not the most complicated thing in the world, but part of this book’s appeal is the fact that it shows the entire journey to the reader. While is true that it is up to every single person to make a change in their lives, this book is a very strong companion in that particular experience, and the author definitely knows what he is talking about. A very good book and one that, hopefully, gets the attention it deserves because it has a lot to offer to the general public." (Book Nerdiction Review)
