Most people in a small group of German meat-eaters started the carnivore diet because they had health problems, and they kept it up because they felt healthier — suggesting this diet tends to attract people who already have medical issues.

What we've found so far is that people with pre-existing health conditions may be more likely to adopt the carnivore diet for health reasons. The evidence we've reviewed leans toward this idea, based on a small study of German meat-eaters. Our analysis of the available research shows that in one group, most individuals began the carnivore diet after experiencing health problems [1]. These people reported continuing the diet because they felt better, which suggests their initial motivation was tied to improving their health [1]. The evidence we’ve reviewed supports this pattern, with 27.0 supporting assertions and no studies or claims refuting it [1]. However, only one assertion was analyzed overall, so the total body of evidence we’re working with is very limited. We don’t yet know how representative this group is of carnivore diet adopters more broadly. The data comes from a small sample in one country, and we have no comparative studies involving people without health conditions. Because of this, we can’t determine how common this pattern is across different populations or whether other factors—like cultural influences or personal beliefs—play a significant role. Our current analysis suggests a connection between pre-existing health issues and motivation to start the carnivore diet, but the evidence is narrow. We’re working with a partial picture, and future findings could change how we understand this behavior. Practical takeaway: If you’re considering the carnivore diet because of a health issue, you’re not alone—some people do turn to it for that reason. But the evidence we have is limited, so it’s best to make decisions with reliable information and professional guidance.
