"As I've matured, I've realized the true correlation is between beauty and wellness," she told W Magazine. "You don't see that when you're 20 years old, but as you mature, you start to realize that you can't rely on genetics anymore, and that you must make a conscious effort in your life. It's easy to make, it's not like oh, I have a huge list of things I do. But I am conscious about the decisions I make for myself. And I have noticed that when I feed my body rich, plant-based nutrients, I feel better and I look better. It's that simple." 

"It's about embracing and no longer looking for what's wrong and really being in acceptance of everything," she said at the In goop Health summit, "Gravity is going in directions that I'm not so fond of. I can look in the mirror occasionally and say 'you're lying, I don't look like that.' but the reality is the comfort I feel in my skin is the greatest gift. I wouldn't trade it. I'm just happy to be where I am."

Demi has moves. On Instagram, Demi has danced to Goldfrapp (during a photoshoot), danced with fashion designer Pierpaolo Piccioli ("Dancing the night away with @pppiccioli")  and done a conga line to ring in "Happy 2020!"—plus she's done low-impact dance aerobics with a 15-minute Mirror workout.

"I added into my daily prayer a new mantra: to have the courage to be seen without padding or protection," she detailed in her new memoir, Inside Out. "I couldn't go on fighting my body and my weight; I had to make peace," she said. "I started by giving up hard exercise. I never went back into the gym in the house. Never. … The room it occupied is now my office."df44d9eab23ea271ddde7545ae2c09ec

Demi has starred in Andie swimwear ads alongside her daughters. "It was important to me to include my daughters in this campaign, and I hope others seize opportunities in their lives to create meaningful connections and celebrate every moment with the people they love," she wrote, saying the campaign represented "togetherness and showing up for the people you love," so "it was only fitting that I got to share this moment with the people I love most."
