Being in the public eye can be difficult, especially when it comes to comments on social media. However, Curtis tells Fast Company that she completely avoids comments. "I use social media to sell things and amplify things I care about. Period. The rest is cancer," said Curtis. "I never read one comment. I believe I can do my job and have a private life. I believe in the separation of church and state. I believe that I do not owe anybody anything once I've done my work. I am by nature a super-friendly person, but I also have a very clear boundary of what is appropriate and inappropriate for me to share."

Curtis tells EverydayHealth.com that she makes sure to eat healthy everyday. She says, "I eat a lot of raw veggies as well as protein, and I avoid lots of carbs." Curtis says that this diet helps with her digestive health. 

Curtis makes sure to stay active, and she has some go-to favorite workouts. "I do Pilates, I do yoga, I exercise, I eat very carefully," she said to More. Curtis also makes sure to maintain a sense of humor about her workouts, joking, "I have a name for my middle here. Her name is Midge. When I do Pilates, we talk about Midge. 'Pull in Midge.'"
