Time-restricted feeding (TRF) has shown many health benefits in different organisms, but its effect on lifespan is unknown. A new study showed that a novel intermittent TRF (iTRF) dietary regimen can extend the healthy lifespan of Drosophila. A clock-dependent nightly rise in autophagy drives the lifespan benefits of iTRF.
