Tyra Banks goes undercover as obese woman

Tyra Banks has gone undercover as a 157.5kg woman wearing a fat suit to experience what it's like to be obese.

"It seemed like the last form of open discrimination that's okay, and I decided to put on a 350-pound suit myself and live that life for a day and see what happens," said the 31-year-old former supermodel turned talk-show host.

"I started walking down the street and within 10 seconds, a trio of people looked at me, snickered, looked me right in my eye and started pointing and laughing in my face," she said.

"I had no idea it was that blatant."

The segment will air in the United States on Monday on The Tyra Banks Show.
