Rob Gronkowski has begun to adapt his diet in a way that is similar to Tom Brady's, who has achieved tremendous longevity. 

“Just looking at Tom, seeing what he does every day, what he eats, talking to him, personally one-on-one, just learning about the body with him, just seeing how flexible he is, how pliable he is, how loose he is all the time, every day and ready to go, I just felt like it was the time in my career where I needed to devote myself at all levels,” Gronkowski said.

“I just felt like I had to add on to what I was doing. Find a way that my body will respond so I can perform every day. Be in prevention mode for injuries happening,” said Gronkowski, who recently had his deal restructured with incentives that if reached would make him the highest paid tight end in the league. “I definitely feel like a brand new guy just being able to do exercises here (at TB12). Exercises that help stabilize your core, exercises that help me and my whole body.”

Unlike Brady, Gronkowski does consume alcohol. But for every cup of alcohol, Gronkowski needs to consume at least three glasses of water.
