Katina DeJarnett is a professional competitor eater, chowing down on thousands of calories for work. She said the key to staying healthy is balancing her routine with nutrient-dense foods like salad. She's also a former bodybuilder who loves lifting weights, but doesn't spend long hours in the gym.

Once a competitive bodybuilder, DeJarnett has garnered millions of views since she started her channel in 2019, and revenue generated through viewership is how she and fiancé Randy Santel, also a pro eater, now make their living. “My channel took off in a few months, and that's really an anomaly,” she says.

DeJarnett, known as Katina Eats Kilos online, is a competitive eater who documents her big food challenges on her YouTube account which boasts 689,000 subscribers.

The pair met after Mr Santel messaged Katina DeJarnett to ask her if she would join him for a challenge. He had been invited to try a 'Garbage Can' pizza challenge in Alaska and needed a partner.
