Randy Santal does food challenges practically daily, I don't know how competitive eaters do it. Disgusting way to make a living.
It's gross, but there are things they do to help expand their stomachs. Using high volumes of water and other fluids for days leading up to the competition.
Also they learn how to suppress their hunger ability, so they can just eat and eat.
I watch a documentary about it a few years ago.
It's very unhealthy.
A lot of these people just puke it all up, but apparently Randy and some of the other big name people don't.
The Asian girl who sometimes competes with Randy can eat so much food so quickly, i cannot believe she doesn't puke it all up.
