Randomized Controlled Trial

Human

This study found that people who ate a high-protein breakfast felt like they slept a little better and fell asleep a bit faster than when they skipped breakfast—even though the difference wasn’t big enough to be called 'definitely real' by science standards.

Similar Assertions

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.

91%

Even though people slept less after eating a high-protein breakfast, their sleep was just as deep and uninterrupted — they just went to bed and woke up earlier.

90%

Eating a high-protein breakfast made people sleep less, but they felt like they slept better and fell asleep faster — even though their actual sleep quality didn’t change.

89%

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.

These results only apply to healthy, young, professional adults — we don’t know if they’d work for older people, shift workers, or those with health problems.
