A Kiwi model and competitive eater has posted a hard-to-watch video of herself trying to eat 100 McDonald's burgers.

Nela Zisser, the former Miss Earth New Zealand, has participated in a number of competitive eating challenges this year, posting the results on her YouTube channel, NelaEats.

Previous conquests include a 1.5m Subway sandwich, 2kg of curry and 10 scorpions.

For the burger challenge, Zisser hoped to beat a record set by a another competitive eater.

"The only other competitive eater to do this challenge seriously was a girl from Japan called Yuka," she said. "She managed to get through 62, which is absolutely insane."

To combat "flavour fatigue", Zisser took on 50 cheeseburgers and 50 chicken burgers, with cups of juice, milk and water to help wash them down.

The resulting video shows sped-up footage of Zisser munching through the burgers, which clearly became an increasingly laboured task.

She was unable to beat Yuka's impressive number, but made it through 45 of the greasy offerings in just under two hours, with no breaks.

"It felt like a really long time," she said on completion.

"I probably could've done more if I'd given myself a break and just relaxed for a while but, to be honest, the taste just got to me in the end and I don't think I could do another one.

"I don't know how she did 63, that's a lot, I couldn't do one more little one, let alone that many."
