and Castaldo et al., on the other hand, reported that a ketogenic diet was more effective than a low‐fat diet in reducing the levels of inflammatory factors, such as IL‐6 and TNF‐α, in patients with NAFLD who were overweight for 6 months (Jonasson et al. 2014; Castaldo et al. 2021). This evidence concerns the gene IL6 and metabolic dysfunction-associated steatotic liver disease.
