Diane Keaton used to consume up to 20,000 calories a day when she was battling with bulimia.
The 68-year-old actress, who suffered with an eating disorder in her twenties, admits she would snack on calorific treats and the make herself vomit and, although she no longer makes herself regurgitate food, she believes she will always be an "addict in recovery".
Speaking on 'The Dr Oz Show', she said: "It was, of course, the lowest point of my life ... I was a fat person, I was an obese person, who had somehow tricked myself and managed to hide it. So when you're living with a lie for four years ... all I did was feed my hunger, so I am an addict. It's true. I'm an addict in recovery, I'll always be an addict. I have an addictive natural to me."
However, the blonde beauty insists she's no longer addicted to food and has switched her attention to her adopted children Duke, 13, and Dexter, 18.
She added: "Now it's [my addiction is] work orientated or trying to raise my children as best I can, even though they're teenagers and not really children anymore.
"But really, I identify with those people [bulimics] and I feel for them."
