Katina DeJarnett, from Washington, began competitively eating in April 2019 after seeing a number of restaurant challenge videos on YouTube.
The 29-year-old had tried out professional bodybuilding, and admits she was always hungry while dieting for the competition.
So she decided to try a more food-focused hobby, and quickly discovered she had a talent for competitive eating.
Katina started filming videos of herself eating enormous amounts of food in a single sitting, with her most impressive amounting to 16,000 calories.
She has since racked up more than 200,000 fans on social media with her clips.
The professional eater weighs just 126lbs, and is a size two, a figure that she maintains with a carefully-controlled diet away from her food challenges.
A ripped woman who weighs just 126lbs has revealed she can consume a staggering 16,000 calories in a single day - baffling strangers who are left stunned at how she maintains such a svelte figure while binging on high-calorie foods.
Professional eater Katina DeJarnett, 29, from Washington, is a slim size two, but she can put away an 11-pound Mexican feast of tamales, burritos, enchiladas and tacos, and a seven-pound breakfast dish including nine-inch pancakes, reindeer sausage and a one-and-a-half-pound cinnamon roll in one sitting.
Katina started competitively eating in April 2019 after taking part in a bodybuilding show. During the dieting process for the competition, she found herself extremely hungry and decided to focus her energies on another hobby.
Katina watched restaurant challenges on YouTube and decided to try one herself after the competition was over.
She bought a cheap camera and filmed herself at a local restaurant challenge, eating the 'Fatburger XXXL Kingburger', a cheeseburger with three half-pound patties, and later uploaded the video to YouTube.
After her success, she started pursuing larger restaurant challenges, and tried calorie challenges too – with her toughest so far being 16,000 calories consumed in one day, gorging on fast food, cookies and peanut butter.
She now has more than 200,000 loyal subscribers following her on her quest to tackle food challenges across the world.
In July 2020, she met fellow professional eater Randy Santel, 34, from Missouri, while doing a food tour in Alaska.
They bonded over their mutual passion for eating challenges and travel, and became a couple during their 10-day trip.
Katina and Randy plan to spend 2021 touring the world together and taking part in global eating challenges.
'Growing up, I always loved food and have always been a big eater. I could eat a huge burger and fries faster than my dad when I was six years old, and I'd still ask for seconds,' Katina said.
'I got into video gaming in my teenage years and became overweight. By 21, I weighed 158lbs and decided to quit gaming.
'I got into bodybuilding, and in April 2019 I competed in a local women's physique bodybuilding show.
'While preparing for the show, I was always extremely hungry as I was dieting, so I started watching videos on YouTube of competitive eating and food challenges to compensate.
'I ended up placing in the top five of the bodybuilding show, and decided to bulk up and gain more muscle – all while putting my huge appetite to use.
'I bought a cheap camera and went along to a local restaurant challenge, which was a relatively small two-pound burger that had to be eaten in 20 minutes.
'I was still hungry after finishing, and it motivated me to find harder challenges. I pursued larger restaurant challenges, always recording them and uploading them to my YouTube channel, and then started doing home challenges too.
'During a challenge, I try to eat as quickly as possible so my stomach doesn't have time to tell my brain I'm full.'
Katina has consumed up to 16,000 calories in one day.
But on a typical day, she eats just one large meal with plenty of leafy green vegetables, whole grains and protein.
'I'm careful to balance my calorie intake, and generally aim to eat between 18,000 and 20,000 calories per week,' she said.
'If I film a restaurant challenge that is 7,000 calories, I know I only get to eat 11,000 for the remainder of the week.
'I'm also active in the gym and take at least 10,000 steps a day, so this and my understanding of nutrition helps me to control my weight.
'I generally only do one food challenge a week, but when my boyfriend and I tour in 2021, it's likely that we'll do them more frequently, so I'll probably gain some weight.
'I get asked how I maintain my weight all the time online. Some people will stumble upon my videos and think it's gluttonous, rather than realizing I eat a calorie-controlled diet overall.
'I just happen to eat a ridiculous amount all at once as opposed to spreading it out. Dealing with negativity or harsh opinions is just part of being in the public eye and, for the most part, the viewers are very positive and supportive.'
Katina's worst food challenge was the Screaming Demon Wings challenge in Spokane, Washington.
She ate a pound of hot wings with no water, and the chicken was covered in a spicy gravy that was 'incredibly painful' and caused her sickness for over a week afterwards.
'The hardest part of an eating challenge is overcoming flavor fatigue – which is when your mind gets sick of a certain flavor and tells you not to eat anymore,' she said.
'It becomes hard to continue eating even if you aren't physically at full capacity. It can be a struggle to swallow each bite.
'But mostly I love doing the challenges. My favorite memory was in Amarillo, Texas, completing the seventy-two-ounce Big Texan Steak challenge.
'I had wanted to try it ever since I was a teenager because the restaurant sets you up on stage, and it is just a very fun environment with a supportive crowd.
'Challenges are a bit like putting on a show, it's just a blast. I do it for entertainment – and because I love a good challenge.'
