Tyra Banks: 'I know the pain of being too thin and too big'
The America's Next Top Model creator opens up about body image issues
Tyra Banks is not one to keep her self-doubt a secret.
When the supermodel and her mother, Carolyn London, launched a program in 1999 to mentor young girls – the TZONE Foundation – Banks realized the importance of sharing the insecurities she experienced while growing up.
"The summer I turned 11 years old, I lost 30 lbs. and I had a growth spurt," Banks, 40, tells PEOPLE in this week's issue. "And it wasn't even supermodel thin. It was more than that. Some people thought I had an eating disorder." She didn't.
