Figure Lengend Snippet: Circulating levels of free insulin-like growth factor (IGF) 1 ( A ), total IGF1 ( B ), IGF2 ( C ), IGF binding protein (IGFBP) 2 ( D ) and leptin ( E ) in mice fed chow or a high-fat diet (HFD) for 4 months (HHHH), chow diet for 3 months and an additional month on a HFD (CCCH), or HFD for 2 months followed by chow for 1 month and then HFD for the last month (HHCH). ***p < 0.001. a: effect of the sex, b: effect of the diet. NS non-significant. n = 9.
