The Claim

Even though people slept less after eating a high-protein breakfast, they didn't wake up more often or have worse sleep quality — their sleep was just shorter.

In plain English

Even though people slept less after eating a high-protein breakfast, they didn't wake up more often or have worse sleep quality — their sleep was just shorter.

See the scientific wording

In healthy young professionals (n=13), total sleep time reduction from a high-protein breakfast occurs without changes in sleep efficiency, suggesting the shorter sleep duration does not reflect poorer sleep quality.

  1. Study: A pilot study assessing whether the consumption of a protein‐rich breakfast improves appetite control, eating behavior, and sleep quality compared to skipping breakfast in healthy young professionals

    People who ate a high-protein breakfast slept a bit less, but their sleep was just as restful—so sleeping less didn’t mean they slept worse.
