Kristen, a vegetarian since she was a kid, dabbled in veganism for five years. However, in late 2017 she added some animal products, including humanely raised dairy and eggs, back into her diet. "I think being vegan is a wonderful way to live and it has great effects on the body," she told Today. "I also think it has really good effects on the environment." She detailed her daily diet to Shape, starting with an egg white, spinach and fetal scramble with hot sauce for breakfast, followed by a salad with fruit and veggies for lunch, usually with produce from her garden, unch is usually a salad with any fruit and veggies she can find, including those she grows right in her garden. She sources protein creatively, for example by eating chickpea pasta.

2. Meditate

Daily meditation is part of Bell’s self-care routine. "Meditation makes me feel more rested than a full night's sleep," she told Live Happy magazine. "I do transcendental meditation a couple times a week and have a mantra that I repeat in a still, calm position. I really enjoy powering down for 20 minutes because it’s like shutting off light switches in my brain. I should make more time for it, but meditating even a couple times a week makes a big difference in my stress and happiness levels."

3. Do Cardio and Strength Training

Kristen also breaks a sweat. "Most days, I run or lift weights for at least 30 minutes," Bell has revealed about her workout routine. "Or I'll take a CrossFit class on indoorphins.com." She also likes pilates and SoulCycle.

4. Do “Microworkouts”

Bell is also a fan of microworkouts, short but sweet exercise sessions. "I find if I can make tiny bargains with myself, I can incrementally move forward. Like I will say, 'Today all you have to do is jog for seven minutes.' 'Today all you have to do is jog for 10 minutes.' And I rarely go past 15 or 20, if ever," she told Women's Health. "If you give yourself realistic, attainable goals, you can totally achieve them—and that sense of triumph will make your workout feel even better." The most important thing? "Just getting moving in any way, whether it's taking a walk with them or running around on their bikes in the driveway with them. So then my body just doesn't feel stagnant," she added to Self.

5. Sweat to Destress

Bell exercises for her body – and her mind. “Exercise should be the first stop for anyone who experiences depression or anxiety because it encourages serotonin and endorphins,” she explained to Women’s Health. “I feel so much more centered, patient, capable. It sets the next 48 hours for me.”

6. Avoid Alcohol

Bell, married to Dax Shepard who is sober, rarely drinks. “I maybe have one drink a year solely because I think I might be allergic to alcohol,” Kristen told Women’s Health. “When I do have a drink, I experience the flu the next day. This isn’t normal. No one should have this much of a hangover over a glass of wine.”

7. Stay Away From Gluten

In 2019, Bell “woke up” with celiac. “I don’t know what the f**k is going on,” she told Women's Health. She went on to explain that she found out she had the genetic marker for celiac disease. “Who knows what that means yet but I am experimenting with being completely gluten-free, which is very annoying to do, but I think it is going to help my eczema.”

8. Cheat

Kristen gives herself wiggle room with her diet. “I’m not super restrictive,” Bell told Women’s Health about her diet. “If they make au gratin potatoes, I’m going to have some, but I am mindful of the portion I take. I find that through conscious eating, I’m able to have all the rewards and also maintain a healthy, steady diet.”

9. Try Cold Plunging

As Bell demonstrates her latest Instagram video, she enjoys cold plunging. “Studies have shown that cold plunging can increase dopamine concentrations by 250 percent. Gimme that ‘feel good’ hormone baby!” she wrote in the caption. “It’s also said to not only improve your mental state at the moment, but also helps with mental acuity and alertness throughout the day. BRING IT ON.”
