Summary

Compared fasting, low‑GI, and high‑GI meals and frequencies during simulated night work; higher GI increased glycemic variability.

Why It Matters For Night Shift Workers and Night Owls

Alternating conditions in this trial whether keeping most calories in a daytime window, with minimal overnight intake, found blood sugar 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.
