The Tom Brady diet—also known as the TB12 diet—is a high-protein, plant-based diet that excludes gluten, dairy, corn, soy, MSG, coffee, alcohol, GMOs, sugar, trans fats, overly processed foods, and more. Some fruits and vegetables such as nightshades are off-limits, as are certain oils.
Since meeting in 2010, Gronk and Brady have developed a friendship on and off the field. The duo has won four Super Bowls together, most recently in February with the Buccaneers. Gronk told Insider that following Brady's diet advice has kept him at the top of his game.
