When basketball star Shaquille O'Neal was 16, he grew 2 inches in one 48 hour period. He was extremely hungry from the caloric necessities of the growth, but he was also in excruciating pain. After 15 hours in the hospital, during which time he ate over 10 pounds of food, he was in such pain that doctors induced a coma and let him sleep until he stopped growing. While he was unconscious he was fed through a tube. His body consumed over 50,000 calories.
