title: Fighting fat with muscle: bulking up to slim down.
abstract: Akt1 is a well-characterized mediator of muscle hypertrophy. In this issue of Cell Metabolism, Izumiya et al. (2008) reveal a striking link between Akt1 signaling, fast muscle fiber size, and whole-body metabolism. These results provide new insights into the ability of muscle to combat diet-induced obesity and metabolic dysfunction.
