You Are What You Eat: A Twin Experiment

Must-WatchSeries

Stanford researchers put 22 sets of identical twins on opposite diets for eight weeks. This Netflix series watches what happens — a rare, real-time look at how food reshapes the body.

Episode Summary

Most nutrition debates are impossible to settle because no two people are alike — so Stanford's Christopher Gardner used identical twins. One sibling in each pair ate more plants, the other didn't, for eight weeks, and this Netflix series follows the whole experiment. It's the closest thing to a controlled look at 'does this actually work,' and the measured changes — in cholesterol, inflammation, and more — are hard to argue with. A bingeable, four-episode watch for the skeptic in your life. (2024)

The People Behind It

Louie Psihoyos

Director (Oceanic Preservation Society)

Oscar-winning director Louie Psihoyos and the team behind The Cove built this four-part Netflix series around a genuine Stanford study. Because the subjects are identical twins, the experiment controls for genetics in a way most nutrition debates never can — so what you're watching is about as close to a clean comparison as food science gets.
