Hailey Baldwin reveals what she eats in a day. With a Tommy Hilfiger campaign and multiple magazine covers under her belt, Hailey Baldwin has one of the most desirable bodies in the modelling business.

The 21-year-old, who is engaged to Justin Bieber, shares the secret behind her clean sugar and gluten free diet.

In a recent interview with Elle US, the model says, ‘I try to be very strict about eating just for my skin and my body’, adding that hydration is key.

“I think drinking a lot of water helps. I try to drink a couple of bottles throughout the day. I don’t know how many glasses that would amount to, but it’s important”

On a regular day, breakfast is usually “eggs or oatmeal, some type of healthy protein, or a smoothie.”

“Lunch is usually salad, fish, grilled veggies, or maybe a sandwich,” she says. “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.”

For dinner, she keeps it simple. “Dinner is usually kind of along the same lines [as lunch] — some sort of vegetable or pasta, 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”.

Rather than indulging in one cheat meal, Hailey likes to make a day of it.

“The first thing I crave, I 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”.
