People in Germany who eat only animal-based foods for about a year often say they feel healthier, have more energy, think more clearly, and feel better if they had health problems before.

What we've found so far suggests that people in Germany who follow a carnivore diet for about 12 months often report feeling healthier, having more energy, and thinking more clearly, especially if they had health concerns before starting the diet [1]. Our current analysis shows the evidence we’ve reviewed leans toward these self-reported benefits. We analyzed the available research and found 27.0 supporting assertions and no studies that refute this pattern [1]. All the evidence we’ve reviewed so far comes from reports where individuals described their own experiences after eating only animal-based foods for around a year. These personal accounts frequently mention improvements in energy levels, mental clarity, and overall well-being, particularly among those who struggled with health issues beforehand [1]. It’s important to note that what we’re seeing is based on how people feel and describe their health—not on clinical measurements or controlled trials. We cannot determine from this evidence alone whether the diet caused these changes, only that people tend to report them. Also, no studies in our current review contradict these reports, but the total number of assertions analyzed is very limited. Our analysis is ongoing, and what we know may change as more data becomes available. Right now, the evidence we've reviewed is consistent in direction but narrow in scope. Practical takeaway: Some people in Germany say they feel better after a year on a carnivore diet, especially if they started with health complaints. But we don’t yet have enough evidence to say this will happen for everyone—or why.
