Hailey eats a very clean diet, limiting gluten and sugar intake. "I try to be very strict about eating just for my skin and my body," she told ELLE.com. "The association between diet and acne isn't clear — but some research suggests that a diet rich in fish oil or fish oil supplements and low in unhealthy fats and processed or refined carbohydrates might promote younger looking skin. Drinking plenty of water helps keep your skin hydrated," says the Mayo Clinic.

2. She Eats Lots of Plants

Hailey encourages a plant-based diet, with meat sprinkled in. "I tried a plant-based diet for two months during quarantine," she told Harper's Bazaar. "I felt great and I had a lot of energy, but it was not for me. I don't eat a strictly plant-based diet and I do still eat meat. I just don't eat a lot of it. I've picked up more fish, greens, and lentils." She also makes sure to consume "a lot of vegetables and fish, not much meat, minimal dairy,” she added to Byrdie, maintaining that diet isn’t only about looking good. "I just feel better when I eat that way."

3. This Is What She Eats in a Day

Hailey detailed her diet to Elle. "On a regular day, breakfast is usually eggs or oatmeal, some type of healthy protein, or a smoothie," she said. "Lunch is usually salad, fish, grilled veggies, or maybe a sandwich. I don't really eat a lot of gluten so I'm trying to be particular. I love a good kale Caesar salad [but with] no croutons. That's usually one thing I leave out.” And her final meal of the day? “Dinner is usually kind of along the same lines [as lunch]—some sort of vegetable, or pasta, like a gluten free pasta. Chicken, maybe. Sometimes [I'll do dessert]. I really like the Magnum bars, obviously that's a great one. [But I generally try to avoid] sugar. Sugar's a big one for everyone, I think."

4. She Does a Lot of Workouts

Hailey does a lot of workouts. Strength training at The Dogpound is one of her go-to methods. In 2021 the studio shared a video of one of her workouts, which included a sled pull, pull-ups, kettlebell squats, plank pikes, landmine squats, and mountain climbers. Read all about it here. She also loves pilates. "I used to be a dancer, so I love Pilates because it really elongates and strengthens my muscles. That's probably my favorite workout," she told Harper’s Bazaar. "I also recently started to box for some cardio," she added. "I found that remembering the combinations and learning how to move your body in boxing has been good for mental health."

5. She Hydrates

Hailey prioritizes hydration. "I think drinking a lot of water helps. I try to drink, like, a couple bottles throughout the day. I don't know how many glasses that would amount to, but it's important,” she told Elle. “Monday plans = hydrate + hydrate +hydrate,” she captioned a recent snap of herself sipping a glass of ice water in a bikini.
