Hollywood beauty standards are nearly impossible to live up to, especially for women. When Demi Moore's film career took off in the early '90s, she felt pressured to look a certain way, and it took a toll on her health. After giving birth to her second child, Scout, Moore began exercising obsessively to prepare for her role in 1992's "A Few Good Men." "Getting in shape for that movie launched the obsession with working out that would consume me over the next five years," the actor wrote in her memoir (via Women's Health).

According to Moore, her excessive workouts led to a decrease in the breast milk she produced, and although she felt "crushed," she continued her regimen. Moore's body would be on display in upcoming films, leading her to restrict her diet and intensify her workouts. To prepare for "Indecent Proposal," Moore said, "I cut out carbs, I ran and I biked and I worked out on every machine imaginable." For "Striptease," Moore ate very little to pare her body down even further, eating just oatmeal, vegetables, and some protein every day.

It was after having to bulk up for "G.I. Jane" that Moore decided she'd had enough. "I had reached my limit," she wrote. The actor credits meditation for helping her overcome her disordered eating and over-exercising. "I added into my daily prayer a new mantra: to have the courage to be seen without padding or protection," she said.
