"And I know this rigidity, this feeling that if you eat one thing that’s wrong, you’re full of self-loathing and then you punish yourself, whether it’s one cookie or a stick of gum that isn’t sugarless, that I would sometimes beat myself up for that,” she continued.

"How do you have a healthy relationship with food, and say, ‘You know what, I can have one cookie and it’s okay?’ That is such a huge thing for people who wrestle with this.”

Demi has battled with her own demons and was treated for “emotional and physical issues” in 2010.
