FGF21 is not required for glucose homeostasis, ketosis or tumour suppression associated with ketogenic diets in mice.

ABSTRACT:

Aims/hypothesis

Ketogenic diets (KDs) have increasingly gained attention as effective means for weight loss and potential adjunctive treatment of cancer. The metabolic benefits of KDs are regularly ascribed to enhanced hepatic secretion of fibroblast growth factor 21 (FGF21) and its systemic effects on fatty-acid oxidation, energy expenditure (EE) and body weight. Ambiguous data from Fgf21-knockout animal strains and low FGF21 concentrations reported in humans with ketosis have nevertheless cast doubt regarding the endogenous function of FGF21. We here aimed to elucidate the causal role of FGF21 in mediating the therapeutic benefits of KDs on metabolism and cancer.

Methods

We established a dietary model of increased vs decreased FGF21 by feeding C57BL/6J mice with KDs, eithe
