Hmmm...says Grok:

Yes, it’s possible to survive on a diet of only red meat, eggs, butter, water, and salt—often called a carnivore diet—but there are significant considerations. This diet provides ample protein, fats, and certain micronutrients like iron, zinc, and B12, which can sustain basic bodily functions for extended periods. Some people, like those following strict carnivore protocols, report thriving on it, claiming benefits like reduced inflammation or improved energy.

However, it lacks fiber, vitamin C, and other nutrients found in plants, which could lead to deficiencies over time, such as scurvy or gut health issues. Long-term risks are understudied, and medical consensus warns of potential heart disease from high saturated fat and cholesterol intake, though some argue this is overstated. Individual responses vary—genetics, activity level, and pre-existing conditions play a role.

Historical examples, like Arctic explorers surviving on meat-heavy diets, suggest short-term feasibility, but they often supplemented with other foods when available. Consult a doctor before trying, as nutrient imbalances can be serious. If you want, I can search for recent studies or anecdotes on X about carnivore diets to provide more context.
