Regulated cell death (RCD) has long been conceptualized as a genetically encoded signaling process, yet its outcome is ultimately dictated by cellular metabolism. Here, we propose that cellular metabolism functions as a gatekeeper of RCD, establishing permissive or restrictive states that determine cell fate. Bioenergetic capacity, redox balance, lipid composition, and metal availability impose metabolic constraints that bias cells toward survival or distinct death modalities. At the systems level, organelle-resolved metabolism and inter-organelle communication coordinate the spatial control of death processes. We further position RCD pathways along a metabolic continuum, ranging from energy-dependent apoptosis to chemistry-driven ferroptosis. This framework explains the plasticity of death responses and suggests that metabolic reprogramming can redirect cell fate. Targeting metabolic dependencies thus offers a strategy to control cell death in disease.
