Skeletal muscle morphology in mice after 14 months on a control (CON) or ketogenic (KETO) diet. Muscle sections from 26-month-old mice were stained for type I (blue), IIa (red), IIx (black), and IIb (green) myosin heavy chain. Note the increase in oxidative (blue and red) fiber number and size and the concomitant decrease in glycolytic (green) fibers. [Adapted from (21). © 2021 The Authors. CC BY. Used with permission.]
