In this issue of Developmental Cell, Nguyen et al. (2017) show that lipid droplets serve a dual purpose during starvation. First, they act as an energy source by supplying fatty acids for mitochondrial β oxidation. Second, they sequester toxic lipids that arise during autophagic degradation of membranous organelles, thereby protecting mitochondria. Copyright © 2017 Elsevier Inc. All rights reserved.
