If I starve myself from morning to dinner time, I bet I can eat it in 3 hours.
Problem is, when you starve yourself, your stomach shrinks, and wouldn't be able to fit the food in. If I ate heavy for about a week every meal, then the day of this event, I crushed a HUGE breakfast and waited 6-8 hours, I might be able to get 3/4 of it down, but I'd probably puke..
There are literally a very limited amount of people in the world that could take that beast down. Like 0.001% of the world's population. People tend to underestimate how much food that actually is..
