1. She Is Active

“Don't stop moving because you'll rust. You have to grease the joints and keep moving," she told The Cut. "As long as I do that I feel great. If you start to hold still, they'll start acting up." Christie is a genius at incorporating exercise into her life. "While I'm brushing my teeth, I'm doing leg lifts. When I'm drying my hair, I do all kinds of squats,” she added.

2. She Eats Big Meals in the Morning

"A lot of mornings lately I will take a bowl and I throw some oatmeal right into it," she dished to Shape about her diet. "I rarely have time to cook it so I just eat it raw. Then I'll pour some flax seed on top of that and maybe a little wheat germ, then I'll grab a couple of handfuls of blueberries, blackberries, raspberries and rinse them off, toss them in and then I pour one of those Dannon things on top and stir it up. I always describe it…it's like a really moist juicy muffin. It is so good. I feel like it is giving you a lot of good things. You can also throw a handful of walnuts in there."

3. She Eats As Plant-Based As Possible

"I haven't touched a piece of meat since I read a graphic description of Chicago's slaughterhouses when I was 12," she told Harper's Bazaar. Instead, she tries to eat as plant-based as possible. "I call myself a flexible vegan because, you know, Italy exists. Mozzarella and pasta exist. In France, I may have to have a piece of Camembert, you know. Un petit sandwich au fromage,” she added to The Cut.

4. She Consumes Lots of Colors

Christie is a big fan of the rainbow diet. "For lunch, I go into greens and do a salad, then add a protein like a bean or nuts," she told The Cut. "For many, many, many years, I've always said go for as many colors as possible in a day," she said. "That's my main concept for making sure my kids get all the nutrients—making sure the deep greens, yellows and reds and purples, all of that."

5. She Drinks Warm Water with Lemon

"I start every day with warm water and lemons. It's something I picked up on my Instagram," Christie told The Cu about her go-to morning drinkt. "Some days I alter it, and I get fancy and I put a little bit of mānuka honey on the rim of the glass, turn it upside down, and dump it in red cayenne pepper. Then I put the lemon juice in and then the hot water. That's when I have a little time. I figure that the pepper gets my system all revved up, and the lemon water gets everything flowing through."
