Eating disorders are dangerous, terrifying and difficult ordeals — and no one is immune. Some of the most beautiful celebs on the planet have battled demons and body image issues. These stars have all come forward about their struggles with eating disorders, and many of them still serve as role models to everyone who’s ever fought with food-related issues.

Demi Lovato

Demi Lovato is probably the most open celeb there is. She frequently shares wisdom, as well as true tales, of her struggles with her inner demons, which ranged from self-harm to bi-polar disorder to bulimia. And thanks to her, she and her beloved Lovatics are able to stay strong.

Kesha checked into rehab for bulimia. The ‘Tik Tok’ singer explained, “I’m a crusader for being yourself and loving yourself, but I’ve found it hard to practice. I’ll be unavailable for the next 30 days, seeking treatment for my eating disorder… to learn to love myself again, exactly as I am.” Her mom checked in shortly after to cope with the post-traumatic stress disorder she claims came with the stress of K-Dollar Sign’s illness — as well as their ongoing battle with Dr. Luke.

Lindsay Lohan opened up to Vanity Fair about her super-skinny — and truly terrifying — days in her 2006 era. She told the magazine she suffered from bulimia, saying, "I was sick, and I was scared too. I had people sit me down and say, ‘You’re going to die if you don’t take of yourself.’"

‘Pretty Little Liars’ star Troian Bellisario admitted she suffered from anorexia. Her struggle to be perfect resulted in not only anorexia, but also self-harm. She explained, “It was about wanting to please my father and mother and wanting to be perfect to everybody. I just thought if I ever expressed [to my parents] any sadness or anger or anything that’s going on with me, they would disown me. I kept a lot of it bottled up inside, and it turned into self-destructive behavior,” she said.

“I felt this sadness, and I thought if people really knew what was going on inside me, they wouldn’t want to hang out with me. So I tried to keep it light and funny. I became imprisoned [by my eating disorder and self-harm]. And it was something I fought with.”

Lady Gaga admitted to her beloved Little Monsters that she struggled with bulimia and anorexia since she was 15. It shed a whole lot of light on her fluctuating weight — and probably made her critics eat a whole lot of crow.

The ‘Fantastic Four’ actress revealed that she struggled with her weight, despite having one of the most sought-after bods in Hollywood. “With treatment I have now conquered the fear that drove me to become dangerously thin," she said.

The onetime ‘Pan Am’ and ‘Addams Family’ star’s eating disorder was reportedly triggered by something she saw on television. “At the time that I was starting to diet and stuff, I saw this TV movie, and I thought, ‘Ooh – anorexia. I could probably do that.’” The actress has since recovered and looks great.

The very first ‘American Idol‘ and girl power advocate wasn’t always so strongwilled. Kelly Clarkson confessed that in high school, she missed out on a role in a musical that went to a thinner but less talented girl, and it hurt her to her core. "I thought if I came back and I was cuter and thinner, then I’d get the role," she said. "It wasn’t smart … and I became bulimic for the next six months." Thankfully, the married mom-to-be is now proud of her curves!

Fellow ‘Idol’ contestant turned erstwhile ‘Smash‘ star Katharine McPhee was envied for her curves and stunning good looks on the show, but she was fighting a private battle throughout. She confessed to suffering from bulimia as a teen, saying, “It was how I dealt with emotions and uncomfortable situations. It was literally a drug." She said that at her worst point, she was purging seven times a day — and it nearly wrecked her voice. Thankfully, she got help to stay healthy and fit and to keep those pipes powerful.

The ‘Jersey Shore’ starlet was under heavy criticism for her weight while she was on the show, but Snooki revealed her up-and-down scale numbers were a result of years of battling an eating disorder. "In high school, I really wouldn’t eat," she said. "It got so crazy that I would only eat a cracker or a cucumber a day and I would feel full." The 4’9" firecracker got help from her school nurse when her weight plummeted to only 80 pounds.
