Video: Bears' Caleb Williams Says He's Doing Tom Brady's TB12 Diet, Talks QB's Advice

As Chicago Bears rookie quarterback Caleb Williams begins his NFL journey, he's learning from one of the greatest to ever do it.

In an interview with ESPN's Courtney Cronin, Williams revealed he's implementing the diet of NFL legend Tom Brady. The diet means Williams can't have white rice, white flour, red sauce, sugar and more. For Williams, he decided to take on the strict diet to increase his chances of having a long and successful career like Brady.

"Obviously he has the knowledge of 22 years, however long he played, of playing ball and being healthy," Williams said of Brady (16-minute mark). "That's ultimately what I'm trying to reach, is to play that long, play as long as I can and be healthy throughout all of it. A big part of it is the diet and working out and how you work out. And then getting on the field the mental part, the physical part takes over. But the things that I can control, control those things, which is my diet and that's a big key to be able to play for such a long time."

Williams also said that he reached out to Brady to get some advice before he begins his career. The seven-time Super Bowl champ emphasized the importance of staying motivated throughout the process, even when things get difficult.

"He kept harping on competitive stamina, he kept harping on being around your guys, understanding them, that relationship," Williams said (18-minute mark). "And then, just, it's hard. The job is hard, it's a tough job. It's tough to go out there and win games. So doing the best you can in the film room, with your diet and all the other things you can control. Go out there and handle those things and it gives your chances of winning games and doing what you want to do, it gives you the best chance."

Williams, the top pick in the 2024 NFL draft, enters his rookie year with plenty of expectations after a successful tenure a USC. He'll begin his rookie season on Thursday in the Pro Football Hall of Fame Game between the Bears and the Houston Texans.
