Not sure if this is a good idea, watching the big eaters on You Tube they all seem to be fairly fit. See Matt Stoney, Leah Shutkever, Joel Haver, Mom v Food, Beard meats food, Raina Huang, Max v Food and Katina Eats Kilos.
The only 'larger' eater would be Katina's SO Randy Santel, and I think he's slimmer than the guy in the photo; although probably taller!
I think he meant Joel Hanson. Him and beard both wear size medium t-shirts and will ruin your profitability for the day in one meal. If you treat them with respect though you'll get it back and more through free advertising.
Quick edit to add, heavy guys can never outeat the skinny pros. You get a fat belt that won't let your stomach stretch. It's very real.
