People who eat a high-protein breakfast sleep about 36 minutes less per night than when they skip breakfast, but the quality of their sleep doesn't change.

See the scientific wording

In healthy young professionals (n=13), consuming a 350-kcal high-protein breakfast significantly reduces total sleep time (TST) by approximately 36 minutes per night compared to skipping breakfast (381 vs. 417 min, p<0.05), without affecting sleep efficiency.
