Daytime Eating During Simulated Night Work Mitigates Cardiometabolic Changes
Summary
Keeping meals to daytime during simulated night work mitigated adverse changes in cardiovascular risk factors vs eating at night.
Why It Matters For Night Shift Workers and Night Owls
Participants randomized in this trial whether keeping most calories in a daytime window, with minimal overnight intake, showed sleep, alertness, recovery, and metabolic markers for night‑shift workers and night owls. The signal puts timing—rather than only calories or macros—at the center of how bodies respond to working at night. For people who work nights, that frames an everyday choice (when you eat, how you light the end of a shift, how rest is split) as part of the mechanism, not just routine.
