Julianne Moore does yoga to help her stay healthy and fit. She’s been quoted in the past about her love of yoga, but in the latest issue of Health magazine, she opens up about her diet and fitness regime.

Julianne says she tries to do Ashtanga yoga at least two to three times a week. She also says she gets regular acupuncture treatments and uses Chinese medicine to help her stay well. “When I was making Safe, actually, I got so thin that I stopped having my period and my blood pressure got dangerously low. And the only thing that really got me back to normal was Chinese medicine.”

Health also got Julianne to talk about what she considers an important part of a yoga practice: diet. “I did a silly juice cleanse (before the Golden Globes) for three days, which went all over the Internet as if I was a lunatic. I was eating vegetables, not eating sugar, being really careful. And when I was in yoga that week, I was so much more flexible. My teacher said, ‘Wow, you’re really bendy.’ I’m like, ‘That’s what it is. It’s the food!’ Because then you realize how important diet is. Dairy, sugar, alcohol—all those things affect you.”
