A content creator found out that a meat-only diet isn't the healthiest option, in one of the hardest and most unforgiving ways possible.
The TikToker took it upon herself to practice the diet when she was in university, but paid the price with a trip to the hospital.
Eve Catherine, from Dallas, USA, has over 49,000 followers on her account, with her story about how her carnivore diet caused her to end up in the hospital going viral with over 154,000 views.
But with the diet being backed by celebrities such as Joe Rogan, the social media influencer is determined to spread word that it's not all it's cracked up to be.
Having steak everyday sounds like a great idea in theory for some (Getty Stock Photo) As explained by Harvard Medical School, the carnivore diet can be hazardous to your health, despite being a popular 'keto' option for those looking to lose fat.
In fact, it can result in you having high levels of LDL cholesterol, known as bad cholesterol, as animal fat mostly contains saturated fat.
It can also lead to impaired kidney function.
A carnivore diet usually consists of meat, poultry, eggs, seafood, some dairy products, and water.
Vegetables, fruits, or any greens for that matter, are off limits, which is why it's known as the 'zero carb' diet.
Eve explained that she was in her 'era of being a carnivore', saying in the video: "I was eating a New York strip steak every single night my senior year of college. In the morning, I would eat two or three eggs.
"I would eat this specific type of yogurt that had 19 grams of protein in just one cup. Any snack that I had or anything had to be protein-centric," she pointed out.
While a regular physical indicated that she had high protein levels, things started to go downhill as she thought she was going to die after seeing blood in her urine.
After being taken to the Emergency Room, she revealed that she was 'screaming' when she went to the toilet, as she passed a kidney stone.
Despite this, Eve was made to wait.
Kidney stones can be caused from excess waste product and forms in the ureter, which connects your kidneys to your bladder, according to the NHS.
In a painful process, your body will try to pass it out when you pee - kidney stones can also lead to infections or malfunction of the organ if untreated.
After finally seeing a doctor, he questions if it's just her period, which she rejects, explaining that she passed a kidney stone moments before.
"He does the X-ray thing to make sure there's not anymore. I had to be put on morphine because it hurt so bad," she recalled.
Kidney stones can be caused by eating too much animal meat (TikTok/evecatherine.r) Diets with high protein can cause the body to excrete more calcium through urine, and the excess amount of calcium can cause the body to make uric acid, and too much of this can result in the build up of uric acid stones in the kidneys.
Kidney stones can also be formed from excess calcium and oxalates from plant-based foods and the body.
Eve concluded the video, urging viewers: "Don't eat too much protein, OK?
"Don't neglect your fiber intake."
Kidney stones are common in the UK, with more than one in 10 people suffering with the condition.
