Last year's smash hit reality show The Biggest Loser is back for a second season on Tuesday. A new group of overweight contestants will be challenged to lose weight while facing real-life temptations. This season, seven men will face off against seven women. The contestants include a stand-up comic who uses comedy to mask his weight issues, a cancer survivor, and a tough female NYPD officer.
