The Study
Carnivore Diet: A Scoping Review of the Current Evidence, Potential Benefits and Risks
This study is like a summary of stories from people who tried the carnivore diet. It tells us what happened to them, but not why or if the diet actually caused those changes. We can’t say the diet helped or hurt — just that some people said they felt better or had certain lab results.
