Published data revealed that in metabolic disorders, especially obesity and fat, kaempferol increased PPARα, PPARδ, and target genes, thereby inducing autophagy and fatty acid uptake as well as decreasing PPARγ and SREBP-1c expression via activation/inhibition of related signaling pathways regulating obesity and metabolic dysfunctions (Table 1) [76–82]. This evidence concerns the gene PPARD and obesity disorder.
