1. She Stays Active

The hotel heiress has joked about how much she hates working out and credits her slim figure to keeping busy daily. Whether she's in a meeting or playing a gig, she's always on the go. Sandy Younan Brikho, MDA, RDN, Registered Dietitian with The Dish On Nutrition says this can actually work. "Living an active lifestyle or staying active helps you stay fit because you are burning more calories. While you might not feel like you are exercising, you are still burning calories. For example, dancing burns calories. Depending on how long you are dancing and how much you are moving your body, you could burn a lot of calories while having fun and being active.”

“You can also burn calories through daily activities,” she continues. “For example: Let’s say you burn 5 calories every time you go up one flight of stairs, and let’s say you go up and down your stairs at least 5 times daily. Then you burn 25 calories daily, 9,125 calories every year, which is a little over 2.5 lbs in one year. If you decide to take the stairs instead of the elevator when you are at work or at the mall, then you are burning more calories through your daily activity.

A few ideas to help you burn calories by living an active life:

• Take the stairs instead of the elevator
• Park your car further away from the entrance
• Clean your home rather than hiring a cleaning service
• Take your dog on more frequent walks
• Go on dates that are more active (ie. hiking, kayaking, walking on the beach, bike riding, etc)
• Do some squats or push-ups during the commercials, while watching TV
• Play with your children or nieces and nephews (ie. hide and seek, tag, etc)
• Go out dancing, or dance in your living room with your family
• Get a stand up desk to work on."

2. She Takes Care of Her Skin

Hilton has mentioned how she learned at a young age from her mom to take care of her skin and stay out of the sun. Dr. Enrizza P. Factor, a Clinical Dermatologist, says, "As people age, it’s natural to experience thinner, drier skin and an increase in wrinkles and other signs of aging. However, your environment and lifestyle choices can sometimes cause your skin to age prematurely. Apply a facial moisturizer every day. Moisturizer traps water in our skin, giving it a more youthful appearance and stop using skin care products that sting or burn. When your skin burns or stings, it means your skin is irritated. Irritating your skin can make it look older.”

3. She Cooks

Well, she's learning to cook and has a Netflix show about it that we're obsessed with! Cooking at home is healthier than eating out Dietitian and Nutritionist Mary Kate Keyes, Director of Nutritional Sciences at Mind First Health & Fitness explains, "Most restaurateurs are chefs, and if they’re lucky have some business acumen; they’re great at making tasty food that turns a profit. Their first priority is getting you to come back for more, not ensuring that your arteries stay clear and your insulin doesn’t spike. Yes, the social aspect of dining out is undeniable and it's fun to be with people you like then not have to wash a single dish, but when you make foods at home you’re more likely to to limit the sugar, salt and fat that’s not that great for your long term mental and physical health."

4. Stays Away from Fast Food

Hilton has been very vocal about loving fast food, especially McDonald's, but lately she admitted she's trying to avoid it. Keyes reminds us, "Food-on-the-go is rarely a three-bean salad stacked with bright peppers and crunchy onion. That is to say, fast food is rarely a high-fiber option. Shocker, I am sure. You know that fiber is one of the great components of vibrant fruits and vegetables, and hearty whole grains. Fiber can fill you up, keep you regular and feed those mighty important good bacteria in your gut. Most fast food can’t hold a candle to foods you can make at home."

5. She Loves Breakfast

The newlywed has mentioned in several interviews how she loves breakfast and Keyes states, "Several researchers have shown that there is an association between eating breakfast and having a lower BMI, but let’s look beyond just BMI which is only one small metric of overall health. Breakfast is how we fuel ourselves after a long overnight fast. Having fuel means that we have energy to do all the things we need and want to do in the morning hours. Skipping breakfast in an effort to eat fewer calories can actually backfire, especially if you wake up hungry. Thank your body by eating when you’re hungry and giving yourself time to eat before your day 'gets in the way.'"

6. She Sleeps

While the solicalite may be known for her party lifestyle, she makes time for quality sleep. According to Keyes, "Sleep is when our mammalian brain cleans itself out. It compresses files, filters out the junk and gets us ready for the day ahead. There is a reason that up to a third of our lives is spent horizontally; it is just that important. Adequate sleep, measured in both quality and quantity helps us make better decisions, helps us reduce anxiety and helps us choose more healthful foods to fuel ourselves."

7. She Eats Organic Foods

The cooking show host has said in the past she only eats organic foods when she's at home and Keyes says, "It doesn’t really matter all that much. The idea that we must eat organic foods to truly be healthy is really a misconception. Traditionally grown fruits and vegetables are also chock full of nutrients like vitamins, minerals and phytonutrients. And for that matter, processed foods with an organic label can be chock full of refined (albeit organic- big whoop) sugars. If you’re worried about pesticides on your non-organic foods, go for variety which will reduce your exposure to any one chemical. If your family loves to go organic and your wallet can support it, go for it, but eating a rainbow of any and all produce is better than none at all because you can’t go all in on organic foods."
