1. She Avoids Gluten

Hailey is very honest about having to be mindful of her diet to maintain her skin health and overall fitness. "On a regular day, breakfast is usually eggs or oatmeal, some type of healthy protein, or a smoothie,” she says. “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."

2. Pescatarian Diet

Hailey sometimes switches to a pescatarian diet, saying it gives her energy. “Eating fish is associated with many known health benefits,” says Sydney Lappe, MS, RDN. “Despite this, most Americans fail to eat the recommended weekly amount of fish. On one hand, the benefits of eating fish include being a source of lean protein, bone-building nutrients, and heart-healthy fats. On the other hand, some people may be intimidated to cook with fish or may not be confident about the healthiest fish options with the lowest mercury risk.”

3. Cheat Days Are Always Allowed

Hailey understands that cheat days are sometimes necessary to stay healthy overall. "A cheat day for me, the first thing that I crave, I'll eat,” she says. “That's my rule. So if I wake up and I want pancakes, I'm gonna eat pancakes. If I want a cheeseburger for lunch or for dinner, I'm gonna eat it. If I want fries, I'm gonna eat the fries."

4. She’s Mindful of Sugar

Hailey loves to bake, but she’s mindful of sugar for the sake of her health. “Cutting added sugars can help to keep your blood glucose levels within healthy parameters and makes it easier to control weight, both of which lower your diabetes risk,” says Linda Folken, MS, RDN, CSOWM, CDN. “Added sugars contribute to excess calories, and excess calorie intake leads to weight gain. Weight gain, along with higher blood glucose levels from consuming added sugars, leads to insulin resistance. Cutting down on added sugars is key in stopping this cycle.”

5. Plenty of Water

Hailey drinks plenty of water throughout the day, saying it’s important for how she feels. "Every day, you lose eight to 12 cups of water through breathing, perspiring, and urine and bowel movements. In general, men need at least 12 cups of fluid daily, while women require a minimum of nine cups," says Allyn Wergin RDN. "Factors that increase your fluid needs include exercise, hot weather, high altitude, a high-fiber diet, and increased losses from caffeine and alcohol intake."

Model Hailey Bieber isn’t afraid to show off her hard work at keeping fit. To that end, Bieber posted a new series of photos of herself modeling different outfits and hats over the week. One of the photos featured her in a bathing suit. She captioned the post, “Past week. Different vibes. Different hats.” How does she stay so fit?

1. She Eats A Plant-Based Inspired Diet

Bieber revealed her workout and wellness routine that she adapted during the pandemic to Harper’s Bazaar. She revealed that she briefly tried a plant-based lifestyle, and while she no longer is doing so, she did adapt some of the qualities in her current diet. "I tried a plant-based diet for two months during quarantine," she explained. "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."

2. She Loves The Ocean

Bieber has incredible skin, and she has even become a spokeswoman for BareMinerals. She says to Harper’s Bazaar that one of her skincare secrets is spending time in the water. "My skin feels the best when I've been in the ocean. Salt water is the best skin healer for me, and I've found that nature can be the most soothing for my sensitive skin."

3. She Does Pilates

Bieber tells Harper’s Bazaar that one of her favorite ways to stay in shape is by doing Pilates. "I used to be a dancer, so I love Pilates because it really elongates and strengthens my muscles,” she said. “That's probably my favorite workout.” "Pilates mat exercises contributed to increase in the strength and endurance of core muscles in post delivered women and even improve the fitness of women by improvement in cardiorespiratory fitness and decrease in the girth measurements," says one study.

4. She Boxes

Bieber also told Harper’s Bazaar that she recently started to pick up boxing to help her stay active. “I also recently started to box for some cardio. I found that remembering the combinations and learning how to move your body in boxing has been good for my mental health."

5. She Occasionally Cheats

While Bieber tries to eat healthy, she also isn’t afraid to give herself a break or a cheat day if she feels like she needs it. "I try to be very strict about eating just for my skin and my body but on a recent trip, I was eating whatever I wanted when I was there because it was just like you've got to take advantage of those moments," she told ELLE. "A cheat day for me, the first thing that I crave, I'll eat. That's my rule. So if I wake up and I want pancakes, I'm gonna eat pancakes. If I want a cheeseburger for lunch or for dinner, I'm gonna eat it. If I want fries, I'm gonna eat the fries."
