PLAIN-LANGUAGE SUMMARY

What it found

Daytime eating prevented the glucose-tolerance disruption seen with day-and-night meals during this laboratory protocol.

Keep these limits in view

This was a tightly controlled experiment, not a long-term trial in workers living with rotating shifts. It does not establish a universal meal schedule or show that the approach prevents diabetes.
