When you think of what models eat for lunch, this is probably not what comes to mind.

Nela Zisser of New Zealand downed a one kilogram burrito in less than two minutes.

Having already won a burger eating contest in April, Miss Zesser was well-poised to polish off a kilo of Mexican food in just one minute and 44 seconds.

In a video that has gone viral, Ms Zisser says “I’m going to try and do this as fast as I can,” and she doesn’t disappoint.

By the end of the clip, Ms Zisser is on her feet literally shoving burrito into her mouth.

Thanks to her efforts, the 22-year-old became the proud female record-holder of Mad Mex’s annual 1kg ‘Big Burrito’ challenge and advanced through to a battle of the sexes against chef Devo Dvious.

Mr Dvious proceeded to take out the overall 2015 champion title.

But we’ll give the moral victory to Ms Zisser for what has to be the least model-like performance ever.

Ms Zisser won Miss Earth NZ in 2013 and also identifies herself as a competitive eater.
