ABC is set for the hourlong special Half Their Size: The People Magazine Weight Loss Challenge, scheduled for Sept. 30 at 10 p.m.

According to Variety, the show will focus on eight residents of Mississippi -- the nation's most overweight state -- for a nine-month period to see how their lives change through diet and exercise.

Half Their Size is a People franchise that began in 2002 and focuses on folks who desperately need to shed pounds.
