Extreme eater Nela Zisser decided to take on New Zealand fast food joint Better Burger’s new stack challenge, and made it even more demanding!The rules require participants to eat a burger with over eight patties, but Nela increased this to 10 patties.She then threw in fries and a milkshake for good measure, showing that when it comes to eating challenges, Nela is still a champion!
