title: Autophagy works out.
abstract: Autophagy is generally considered to be a cytoprotective response to stress, whether in the form of nutrient deprivation or the presence of dysfunctional organelles. He et al. now show in Nature that exercise-induced autophagy is needed for some of the beneficial effects of exercise on metabolism (He et al., 2012).
