Caloric Restriction Mimetics: Targeting Energy Sensing Pathways

Edisnap· Feb 24, 2026

This infographic illustrates how Caloric Restriction (CR) mimetics shift cellular metabolism from a growth-focused state to a maintenance and repair state, ultimately extending lifespan by modulating key energy-sensing pathways like mTORC1, AMPK, and Sirtuins.

Caloric restriction (CR) extends lifespan across species from yeast to primates. The effect is robust, reproducible, and evolutionarily conserved.

But the mechanism is not simply "less food = less damage." CR triggers specific signaling pathways—AMPK, sirtuins, mTOR—that sense energy status and coordinate cellular responses.

Hypothesis: The benefits of CR come from activating energy-sensing pathways that shift metabolism from growth to maintenance. Small molecules that target these pathways (CR mimetics) should replicate CR benefits without requiring dietary restriction.
