Watts often follows an anti-inflammatory diet. She explained to Women's Health in 2020 that she regularly does it when she needs help resetting, eliminating wheat, sugar, dairy, and alcohol from her already mostly vegan diet. It's pretty simple: When you eat unhealthy, inflammatory foods, you starve the good bacteria in your gut. The bad bacteria take over. This balance-imbalance is called dysbiosis. Now, think of the lining of your digestive system like a fine screen (the epithelial lining, to be specific). When bad bacteria start outnumbering the good, the balance falls out of whack and the bugs begin to irritate the lining of the intestines, and the holes in the screen become larger. Bacte­ria, food particles, and other nasty things escape your GI tract and get into your bloodstream, where they begin to attack the body. The body fights back with inflammation, leading to weight gain and bloating, and putting you at greater risk for all the health problems we've been talking about.

When Watts needs to shape up, she works out three to five times per week, often alternating between boutique fitness classes, yoga, and personal-training sessions. "Regular aerobic exercise can help you live longer and healthier. After all, aerobic exercise can reduce health risks, keep excess pounds at bay, strengthen your heart and boost your mood. It can also reduce your risk of death from all causes," says the Mayo Clinic.

Watts doesn't have an all or nothing approach to diet and fitness. "COVID came, and I was like, 'Nah, I'm gonna have a glass of wine when I want,'" she told Women's Health. "I'm stealing the kids' Oreos. I never stop eating pasta. We're baking cakes, banana bread—I don't ever want to see another piece of banana bread after this." She also started eating bacon. "I was closer to vegan before [this situation]," she admitted. 

Watts is a big fan of Taryn Toomey's workout method, The Class, an hour-long workout combining calisthenics and plyometrics with guided by self-help messages, which she streams about four times a week."I've always liked to be physical," she says. "I'm an active person. But I also love the outlet that Taryn creates. It's a 'get your freak on' kind of thing. It doesn't feel like a traditional workout. You get to move your body, but you also get to shift your mind in a way that's really cathartic."

Naomi pumps iron with trainer Keith Anthony. Her favorite moves are pistol and goblet squats (with 25-pound weights), which she does "three sets of 20, until I get to failure." She also does jackknife crunches with a stability ball.

Naomi obviously reaps the physical benefits of exercise, but is in it for the mental health aspect as well. "We've been told the endorphins keep you going and are great for anxiety and depression," she explains. "That all sounded good, but now, we really get to experience that."

Naomi does cognitive behavioral therapy, which she discovered when preparing for a role in the 2017 miniseries Gypsy. "I found the research very interesting," she told Women's Health. "It felt like a practical way of dealing with and managing specific issues within a certain time frame. Being able to improve or change your behavior by breaking patterns makes it tangible and beneficial." She meditates and uses transcendental meditation to help manage her anxiety. "I try to keep it consistent. It 100 percent always makes me feel better."
