Maggie may be 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 told 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." Maggie, who has been body shamed over the years, 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," she said.

Maggie maintains a fast metabolism by eating 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.

"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."

"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." Maggie recently launched her own 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 doesn't just drink green juice, she takes green shots. "Wheatgrass. There is nothing like it," she told Thrive about her shot-of-choice. 

Maggie exercises a lot. She does Jason Walsh's Rise Nation method, Katonah Yoga, and hikes with her dogs is her favorite way to blast calories. "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 eats healthy most of the time, but does encourage cheating every once and a while. "If doughnuts were healthy, I'd have a strict diet of only them," she dished to US Weekly. "I think about my next meal as my current meal is ending."

Every morning, Maggie makes sure to get her nutrients in with the health of 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.
