Matt Fitzgerald thinks you need to start eating like the world's elite endurance athletes. When it comes to that, the man knows best: He's an endurance coach, nutritionist, and author of Racing Weight: How to Get Lean for Peak Performance. And if that weren't enough to put your trust in him, he flew around the world to report on the diet habits of top athletes from over 25 countries for his book The Endurance Diet: Discover the 5 Core Habits of the World’s Greatest Athletes to Look, Feel, and Perform Better.

Through this process, eating habits that impeded performance were gradually weeded out and only those that best supported it survived.

The Endurance Diet comprises five eating habits that are present in the diets of nearly 100 percent of the athletes I interacted with both directly and indirectly in my research. Expressed in the form of rules, they are as follows:
