Effect of diet and aging on skeletal muscle weight and fiber size. (a) Gastrocnemius (GTN), plantaris (PLN), soleus (SOL), tibialis anterior (TA), and extensor digitorum longus (EDL) muscle weight relative to body weight (BW) of 16‐ and 26‐month‐old mice on a control (CON) or ketogenic diet (KD). (b) Average fiber cross‐sectional area (CSA) and (c) fiber size distribution from the GTN of 16‐ and 26‐month‐old mice on CON or KD. Values are expressed as means ± SEM. n = 6 (16‐month CON), n = 7 (16‐month KD and 26‐month CON), and n = 9 (26‐month KD). (#) main effect of age. ($) main effect of diet. (*p < 0.05) comparing CON and KD at 16 and 26 months. (a) p < 0.05 comparing CON at 16 and 26 months. (b) p < 0.05 comparing KD at 16 and 26 months
