"Until this past year — my year of health — I never properly considered wellness from all angles," Rebel Wilson tells Shape. "But I was turning 40 and thinking about freezing my eggs, and the experts told me that the healthier I am, the better the process can go. I get a little emotional when I ask myself why I didn't care about my health before this. It just wasn't a priority, and I didn't know how to do it right."

The actor kicked off her journey at an Austrian health retreat, "which flushed out every toxic substance possible in all sorts of crazy ways," she says. "While there I learned that moderate — not even fast paced — walking is the best way for me to lose unnecessary body fat."

She also works out with her trainer, Gunnar Peterson, three times a week; has been learning how to manage emotional eating; and takes daily supplements. "The thing is, I'm not good at swallowing pills. It would take me 30 minutes. Then I found Olly gummies at Whole Foods. They've revolutionized vitamins for me. I chew them in two seconds," says Wilson, an Olly ambassador. "I take the Olly Prenatal or Women's Multi in the morning. At night I like Heavenly Hair, Undeniable Beauty, and Sleep, which has melatonin — I've gotten my whole family onto those."

All these changes have had an inside-out effect: "Now I feel that thing people talk about — if you're healthy on the inside, you glow on the outside," she says. "I don't want to sound superficial, and looks aren't everything, but I think I'm getting better looking with age."
