1. She Is Open About Her Mental Health Struggles

Selana Gomez has been incredibly candid about her mental health struggles, inspiring so many fans to put theirs first. ​​”I feel great, yeah,” she told NPR in January 2020 when asked about her anxiety. “I'm on the proper medication that I need to be on, even as far as my mental health. I fully believe in just making sure you check in with your doctors or therapist. [Taking care of mental health — ] that's forever. That's something I will have to continue to work on. Yes, I don't think I just magically feel better. I have days where it is hard for me to get out of bed, or I have major anxiety attacks. All of that still happens.”

"Last year on Selena's revival tour, I made sure the dressing room always had veggies and protein and brown rice or whole grains," her trainer, wellness expert Amy Rosoff Davis, told Byrdie. "I made a lot of rice bowls with veggies, protein, and avocado for Selena. It helped give her energy and stamina, which she needed to get through her shows. I also made healthy chicken salad with grapes and celery—it quenched her thirst and the protein filled her up.”

3. She Hydrates

According to Davis, Selena prioritizes hydration. “We always drank lots of water and had green tea when we needed a pick me up—it sure was exhausting at times," she said about Selena’s hydration approach while on tour. According to the U.S. National Academies of Sciences, Engineering, and Medicine men should drink about 15.5 cups (3.7 liters) of fluids a day and women about 11.5 cups (2.7 liters) of fluids.

4. She Does Interval Training

Selena’s workouts are grueling. She and Davis focus on "interval and circuit training—and building a strong core," Davis told Byrdie. "My whole thing is toning mixed with cardio and stretching," she added. In a recent TikTok Gomez gives fans a glimpse of her grueling workout, doing moves like overhead arm raises, weighted squats, weighted leg lifts, donkey kicks, stretches, and crunches with a medicine ball.

Gomez has revealed that her weight tends to fluctuate, something that trolls love to point out. "I really noticed when people started attacking me for that," Gomez said during the interview with her friend Raquelle Stevens on the "Giving Back Generation" video podcast. "And in reality, that's just my truth. I fluctuate. It depends what's happening in my life," she added. However, she admits that the criticism about her weight "got to me big time" and "really messed me up for a bit."

7. She Indulges

Selena indulges in fast food on occasion, and doesn’t care what you think about it. “So I be trying to stay skinny, but I went to Jack in the Box and I got four tacos, three egg rolls, onion rings, and a spicy chicken sandwich," she once said in a social media video captured by the Instagram account @selenagomezecu2.0. "But honestly, I don't care about my weight because people bitch about it anyway," she continued, adding that she's heard people say "you're too big," or that her clothes don't fit. "Meh, meh, meh, meh," she continued. "B**ch, I am perfect the way I am. Moral of the story? Bye."
