A nutrition scientist found that the reality show’s contestants’ metabolisms slowed after participating—and didn’t recover.
According to an excerpt from Food Intelligence: The Science of How Food Both Nourishes and Harms Us by Julia Belluz and Kevin Hall:
It was an unusual laboratory for a metabolism and weight loss study: a sprawling ranch, the former home of the Gillette razor-blade tycoon, nestled in the dusty green Santa Monica Mountains near Malibu, California.
A group of people milled about a hallway in the ranch’s white, Spanish Colonial-style mansion early one morning before breakfast— and they were not exactly chipper. Six weeks into season eight of the reality TV program The Biggest Loser, the contestants were tired.
