McPhee is devoted to exercise. The star works out three or four times a week for hour-long workouts with trainer Simon Carter. "We'll run and we'll, like, in the middle of each intersection do, 20 push-ups or 20 jump squats, and then start running again, and go for four or five miles," the actress told Health, per Self, about their sessions.

Katharine refuses to weigh herself, partly because she suffered from an eating disorder in her younger years. "I stopped weighing myself and doing calories a long time ago," she told Health. 

Katharine eats clean and healthy because it makes her feel good. "I love clean food; it makes me feel good," she told Health. "But the idea that you can never eat a burger and French fries [without gaining] weight five days later? I just don't believe that's true." 

Katharine isn't against the occasional cheat meal. "If there's somewhere special I wanna go – like for Mastro's butter cake or a pizza with some delicious red wine – I break every rule," she told Health. "I'm gonna have the appetizer, the entree, some of your entree, and dessert, just because I love food."

After watching the documentary, What the Health, Katharine was inspired to eat green. She said, "it's basically gearing everybody to be plant-based and vegan. I could never be vegan; I like milk and yogurt and cheese too much. But I've definitely moved more toward the vegetarian route." Other plant-based food she loves? "Well, I love avocado toast. I know it's super trendy but I love it for breakfast; it just feels so nurturing and wholesome and so good going into my stomach. I put a little bit of truffle oil over the avocado with salt and pepper on delicious whole wheat toast," she told Health. "I also like big salads, like the ones at Sweetgreen. I love Sweetgreen." Her favorite combo? "Kale, kale, kale, kale. I love kale. And then garbanzo beans, spicy broccoli, red onion, carrot, feta cheese, cucumbers, and then maybe something crunchy, like almonds. I like to eat a really hearty, full meal that's rich in fiber with good fat, like an avocado, and proteins."

Katharine avoids dieting. "I lost this baby weight without dieting. Zero. Diets are the worst and I've had zero pressure from anyone," she said in a recent Instagram post. "I'll probably gain weight again at some point too. Who cares?"

Katharine loves blasting calories via a certain dancing workout. "More than just a fun workout, Zumba class is a safe space to connect with others, exercise my mental fitness & take my me-time to the next level," she wrote in an Instagram post for World Mental Health Day.
