Chicago Bears defensive lineman David Carter suffered from tendonitis and fatigue in the first few years of his NFL career, and in 2014 decided to switch to a 100 percent plant-based diet. According to GQ, Carter quickly lost 40 pounds on his new diet but gradually got back up to 300 pounds, and Carter says he’s stronger than ever.

Carter broke down his diet in an interview with GQ, and says that he tries to eat 1.2 pounds of protein per day in the offseason, all from plants, beats, rice and grains. He eats 10,000 calories in a normal day, which includes five meals and a number of snacks.
