Fueling the 24-hour shift: rules that survive a real schedule

By Joe Dzubak RD, CSCS, TSAC-F

Commander's TL;DR

Shift work breaks meal-timing advice built for 9-to-5 lifters. Anchor intake to the shift clock, not the wall clock, and pre-decide the first post-call meal.

Evidence suggests circadian disruption changes appetite signaling and glucose handling. A fueling standard for shift workers has to assume interrupted meals, variable call volume, and sleep debt — not fight them.

The workable pattern: a defined pre-shift meal, portable protein-forward options staged for the back half, hydration tied to task cycles, and a written rule for the first meal after the shift ends.

None of this requires an app. It requires a one-page standard the whole shift can follow, and a review cadence to adjust it.

Put this into practice.
