Maggie has been body-shamed because she is thin, but she maintains she is super strong. "My mother is Vietnamese. My father was a skinny Irishman from New York, and I've been an athlete my entire life," she explained to Women's Health. "Don't assume what my strengths are. It just shouldn't be acceptable to make comments about anyone else's body. You never know that person's story." She refuses to let haters get to her. "When you depend on someone else's perspective, you always get judged…People think you're lucky to be skinny, so they have a license to say mean things about your body," she said. "It used to hurt me. Now, it makes me laugh."

Maggie doesn't starve herself thin. In fact, she maintains she has fast metabolism because she eats the right things. "I've raised my metabolism by being an active person, so I need more food than most people. But people tell me that I don't eat actual food. Like, how do you think I function? I don't put anything into my body but the air that I breathe? I can't tell you the number of people who've said I need to eat a cheeseburger. I'm like, really? I need to eat a cheeseburger? You can eat a cheeseburger and I'll be okay over here," she told Women's Health.

Maggie encourages a plant-based diet. "I don't [call myself vegan], because it has become a weird, negative term and people feel very judged by it," she told The Beet. "So I like plant-based better because it's friendlier: It's inclusive. You can't judge people. They have to be where they're at, and you have to accept them for where they are."

Maggie tries to keep her gut healthy. "I have always struggled with gut health," Maggie told Thrive magazine. "Whatever brought that on, I couldn't say, but breaking down foods has been a challenge for me even before I knew what that challenge was." She recently launched a supplement line, ActivatedYou. "I wanted to create a line of probiotics that had everything I was looking for. In my journey to improve my own health, I became extremely passionate about helping others out of the hole I was in."

Maggie encourages taking shots…but not of alcohol. "Wheatgrass. There is nothing like it," she told Thrive about her shot-of-choice. 

Maggie prioritizes fitness. One of her go to workouts is Jason Walsh's Rise Nation method. She also likes Katonah Yoga and hikes with her dogs. "My rescue dogs are my life and hiking with them is probably my favorite form of exercise," she wrote on Qeep Up's site. "We can go for hours and nothing makes them—or me—happier!"

Maggie's diet is incredibly healthy, but she does encourage cheating every once and a while. "If doughnuts were healthy, I'd have a strict diet of only them," she told US Weekly. "I think about my next meal as my current meal is ending."

To make sure she gets all her nutrients, Maggie starts the day with a plant-based drink, shot or bowl. She might take her shot of wheatgrass, turmeric, ginger, and lemon, sip on a blended green juice or a smoothie, or feast on an acai bowl, she revealed to Veg News.
