Despite a whirlwind year, Katharine McPhee has her life under control.The 22-year-old beauty talks about her decision to enter the Eating Disorder Center of California to deal with her bulimia. After discussing her bulimia with her mother, Katharine entered the program, finishing up the three-month outpatient program just days before “Idol” stopped airing the audition episodes and began focusing on the Top 24.

“It’s hard to eat healthy on the road, but as I learned in the center, it’s not necessarily what you eat but how much,” she says.

Katharine McPhee, seen here at the 2006 Billboard Awards, tells Shape magazine she’s been fighting bulimia for years.
