These days Chris Delehanty swears by Grant Petersen’s Eat Bacon, Don’t Jog: Get Strong. Get Lean. No Bullshit. A bicycle designer and writer, Petersen lays out his golden rules to get fit without going crazy.

Petersen kicks conventional wisdom in the butt as he advocates for eating more fat, less protein, no carbs and spending way less time exercising. In 106 pithy chapters (plus recipes), the book doles out advice, insight and wisecracks sans the science jargon and inaccessible language.

Ironically, most of this book isn’t new to Chris. Especially as a type I diabetic, he’s heard most of the content before and has always watched his carbs closely. What’s life-changing is how the information is told. It’s clear, concise and fully explained. And it has helped Chris keep his blood levels normal since he started reading (and re-reading) the book.

Some chapters have brought on important realizations. Chris discovered the power of fat. (Check out chapter 7: “You eat less often when you eat more fat and fewer carbs.”) It’s helping him stay full during his busy days. Now, a breakfast is black coffee with coconut oil (chapter 28: “God is a coconut”) and scrambled eggs with bacon and avocado instead of oatmeal and an egg.

His “aha” moment came with chapter 8: “The dangers of eating too few carbs.” The dangers, you ask? None. Absolutely zilch. Petersen explains by detailing the evolution of our diet. Chris also realized a few of his own mistakes such as a heavy dependence on protein. Chapter 9 (“Too much protein makes you fatter, not stronger”) helped him shift calories towards fats such as avocado.

The fitness chapters advocate for short intense training rather than straight monotonous exercise (chapter 40: “Don’t jog”). His next chapters further explain with “What kind of exercise works best?” and “If your workout requires special clothing, it’s the wrong kind of workout.” He writes that skiing and biking and other sports may be fun, but it’s the short intense (I can’t speak or I will die) sprints that matter physically. These high-impact sprints are what get you in shape. Petersen believes in only 7 minutes of intense activity a day (anything you wear is fine).

Permission to eat bacon, ignore jogging and not obsess over carbs isn’t even the best part. The book is so easy to read and refer to. It’s like having a nutritionist, coach and best friend all at your fingertips…or between two covers. That’s what makes this book indispensable.

Ask Chris about it next time you see him. Or better yet, tell him what you’re reading. Chris is always looking for recommendations.  He first heard about this book from Patrick Daley, a client who’s passionate about fitness and nutrition.
