Tom Brady — TB12 Method

Tom Brady's TB12 brand derives authority from his 23 NFL seasons and seven Super Bowl rings, making him the oldest quarterback to play at an elite level (retired at age 45). The TB12 Method book became a bestseller, while therapy sessions cost $200 each. His restrictive diet—banning nightshades, strawberries, coffee, gluten, dairy, MSG—resembles a paranoid elimination diet, but 23 years of top-tier performance is undeniable. TB12's credibility is 30% stronger than Dr. Oz's (rank #3), whose on-air recommendations were 67% unsupported by evidence. You can mock the avocado ice cream, but not the longevity record.
