A Florida man (of course) in his mid-40s, who swore by the controversial carnivore diet, found himself in a Tampa hospital with a bizarre and unsettling condition—his hands, elbows, and feet covered in oozing yellowish nodes.
For eight months, he had lived almost exclusively on a diet of butter, cheese, and hamburger patties, consuming entire sticks of butter and up to nine pounds of cheese daily. When he finally sought medical help, his body had already begun showing grotesque signs of distress—one of the latest carnivore diet horror stories to make headlines.

Doctors diagnosed the man with xanthelasma, a condition linked to dangerously high cholesterol levels. His total cholesterol had skyrocketed to over 1,000 mg/dL—a shocking number considering anything over 240 mg/dL is already considered high risk for heart disease. Before adopting his extreme all-meat, all-fat lifestyle, his cholesterol had fluctuated between 210 and 300 mg/dL—already elevated but nowhere near the catastrophic levels he reached after months on the carnivore diet.
Despite the oozing lipid deposits forming across his skin, the man bizarrely insisted that his health had improved since embracing his new way of eating. While he admitted that the condition had been plaguing him for nearly a month, it wasn’t pain that finally pushed him to seek help—it was the undeniable horror of what was happening to his body.

The carnivore diet has been touted by influencers as a miracle solution for weight loss and cognitive function. Proponents claim it eliminates inflammation, increases energy, and enhances mental clarity. But as this case shows, the potential long-term consequences can be alarming—fueling a growing list of carnivore diet horror stories.
Across social media, meat-only devotees share their extreme regimens—some consuming dozens of eggs per day, others swallowing whole sticks of butter or raw liver. A former vegan recently went viral for promoting a high-fat carnivore diet, while another fitness influencer swore by eating bone broth and raw organ meats.
But the Centers for Disease Control and Prevention (CDC) remains firm: a balanced diet—including fruits, vegetables, and whole grains—is essential for long-term health. The 2020-2025 Dietary Guidelines for Americans recommend 2.5 cups of vegetables, 2 cups of fruit, and no more than 5.5 ounces of meat per day.
While some carnivore diet followers boast rapid weight loss and short-term benefits, this Florida man’s ordeal is a stark reminder that extreme dietary choices come with real risks. His case study, published in JAMA Cardiology, serves as just another of many carnivore diet horror stories—a cautionary tale for anyone considering cutting out entire food groups in the name of health. At the end of the day, the human body is complex, and while some may thrive on alternative diets, others might find themselves paying the price in unexpected ways.
