How does she approach diet, fitness, and self-care? Here is everything you need to know about her lifestyle habits.

1. Vegan and Gluten-Free Diet

Kate doesn’t consume any animal products. “I'm a vegan and I try and eat gluten free, so it's mostly about that,” she told E! She does cheat on occasion. “I let myself have treats as well. I love French fries and red wine. It's my go-to!”

2. Regular Exercise

Kate makes sure to move daily. "I work out a lot," she told E! "Mentally, I need to work out or else I go crazy." Physical activity is anything that gets your body moving. Each week adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle-strengthening activity, according to the current Physical Activity Guidelines for Americans.

One workout that Kate is a fan of? “I do Bar Method, which I love,” she says. According to the brand’s website, it is “a total-body workout designed to strengthen, sculpt and lengthen muscles through low-impact, isometric movements.”

4. Running

You might also find Kate pounding the pavement. “If I'm on location shooting, I run a lot,” she told E! According to the Mayo Clinic, running is great for cardiovascular health, muscle building, and weight loss. “For every mile run, the average person will burn approximately 100 calories,” they say.

5. Dance

Kate is also a fan of ballet inspired workouts. She maintains that Ballet Bodies workout classes “are an amazing way to keep moving and healthy from the safety of your home,” sharing about it in a post. Dancing is a great workout for many reasons. Not only does it build strength and promote flexibility, but helps you lose weight and even promotes cardiovascular function. A 2016 study published in the American Journal of Preventive Medicine determined that people who engaged in moderate-intensity dancing were 46 percent less likely to develop heart disease or die from it than non-dancers. In comparison, moderate-intensity walkers were just 25 percent less likely to suffer heart health issues.
