The Alia Crum Studies

Alia Crum is a Stanford researcher who keeps running studies that should break everyone's assumptions about how the body works.

She gives people the same milkshake with different labels, and their hormones respond differently. She tells hotel housekeepers their work counts as exercise, and they lose weight without changing anything else. She shows people different videos about stress, and it changes the hormones their bodies produce under pressure.

The pattern across all three: what you believe about something changes what your body does with it. Not as a metaphor. As a measurable biological event.

This three-part series walks through each experiment and what it means for how you think about food, movement, and stress.
