The Role of Discipline and "Cheat Meals"

Despite his incredibly strict regimen, Tyson was known to enjoy the occasional "cheat meal". Stories of him indulging in ice cream and his favorite cereal, Cap'n Crunch, show that even the most disciplined athletes have moments of human weakness.

Cus D'Amato's influence ensured that even his occasional indiscretions were quickly corrected by the rigorous schedule.

The Importance of Macronutrient Ratios

Tyson's diet was a textbook example of high-performance nutrition. The emphasis on large portions of carbohydrates provided the necessary glycogen to fuel his immense energy output during long sparring sessions and calisthenics circuits. Similarly, the high protein intake from sources like steak and chicken breast was crucial for muscle repair and growth, allowing his body to recover from the daily punishment. The balance of these macronutrients, along with vitamins from fruits and vegetables, was the foundation of his physical prowess.
