Santel has now shared footage on his YouTube channel of the epic challenge which involves eating "five 6oz Scottish beef hamburger patties stacked and layered with cheese, ladles of beefy chilli con carne, fried onion rings, and healthy vegetables".

The challenge also included "10 'Not So Jumbo' Chicken Wings, a bowl of creamy Scottish coleslaw, 8 fried chicken tempura, and a giant portion of loaded chilli beef and cheese chips".

Along with all the food, Santel had to also drink a pint of Tennent's Lager.

In the video, which has been viewed almost 200,000 times, Santel became the first person to finish the challenge, eating and drinking the lot in 29 minutes and 20 seconds.
