Biggest Loser contestants reveal how they didn't eat for 10 days and had blood in their urine

Contestants from noughties weight loss show The Biggest Loser have opened up about some of the extreme measures they took to shed the pounds. The hit series, which ran for 18 seasons on NBC and USA, saw obese or overweight people from across the US dropping upwards of 100 or even 200 pounds over a matter of months. Now Netflix has released a new three-part documentary about the programme, featuring people who appeared on the Biggest Loser, as well as producers, the show's doctor, and trainer Bob Harper (although the other coach - Jillian Michaels - declined to take part).
