Celebrity Fit Club is a reality television series that follows eight overweight celebrities as they try to lose weight for charity. Split into two competing teams of four, each week teams are given different physical challenges, and weighed to see if they reached their target weights. They are monitored and supervised by a team that includes a nutritionist, a psychologist, and a physical trainer, the latter of which is former U.S. Marine Harvey Walden IV. The series originated in the United Kingdom on ITV in 2002 as Fat Club, with members of the general public taking part. The show then switched to celebrity participants, and continued until 2006, with Dale Winton as host since the series two. An American version premiered in 2005 on the VH1 network. As of February 2010, it is airing its seventh season.
