(A) Thigh muscle Ucp3, (B) Cpt1b, and (C) Slc2a4 mRNA expression in control (gray bars) and 16 h‐fasted (orange bars) male C57Bl mice of three ages. Data are expressed as the means ± SEM. **P < 0.01 versus 10‐week group under the same feeding condition; ^### P < 0.001 versus 15‐week group under the same feeding condition. ^$ P < 0.05, ^$$ P < 0.01, ^$$$ P < 0.001 versus fed mice within the same age group. Ucp3 – gene of uncoupling protein 3; Cpt1b – gene of carnitine palmitoyltransferase 1 b; Slc2a4 – gene of glucose transporter type 4.
