After struggling with her weight as a child, Jillian Michaels decided that she wanted to help others by becoming a personal trainer and life coach.
Born February 18, 1974, Michaels first graced TV screens as a trainer on NBC's weight loss reality competition show The Biggest Loser in 2005. In 2010, she received her own spinoff, Losing It With Jillian, where she helped families lose weight in one week.
In addition to her television appearances, Michaels is also a New York Times bestselling author, the star of fitness DVDs and video games for Nintendo Wii. She also released a diet pill, Jillian Michaels Maximum Strength Calorie Control, which was sold at GNC stores. Shortly after the pill's release, a lawsuit was filed against Michaels that claimed the pills used false advertising, but she denied the claims.
In her personal life, Michaels has admitted to being bisexual.
