Whether it's a joke or not, Hilton has said "I never really work out in real life, because I am constantly so busy that my life is like a work out. Shopping is my cardio." She has also said her DJ sets are cardio. Dance, in fact, can be good cardio. "The guidelines recommend at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. But even small amounts of physical activity are helpful. Being active for short periods of time throughout the day can add up to provide health benefits," says the Mayo Clinic.

"I love breakfast. That's one of my favorite meals," Hilton explained. "So every morning, I have either French toast or pancakes or a breakfast sandwich and cereal, like Lucky Charms or Frosted Flakes and fresh-squeezed orange juice and celery juice, if I'm trying to be healthy," she told The List.

"I love making lasagna obviously and pasta. I'm really good at doing Italian night. So anything Italian, I love to eat, and that's usually what I have for dinner," Hilton told the List. She calls her speciality her "sliving" lasagna.

Paris once dated a man who advised her on her health. "He explained everything to me," Hilton said of the former nightclub owner. "Now I only eat organic foods when we're at home. He makes me watch documentaries on food, like Fast Food Nation, and he makes me aware of what things are good for your body because he's very into that."

Hilton promotes a botanical stress supplement. "2020 was a tough year for everyone, in so many unimaginable ways. I decided 2021 was going to be my reset year. I was going to share my full story, confront my past and begin to conquer the stressors that have impacted me every day," said Hilton. "I was introduced to R3SET on a photo shoot last year. I was exhausted and stressed out. R3SET has become my secret weapon in managing stress. It works for me. I feel more focused during the day and sleep better at night. With the results and my renewed focus on self-care and wellness, I contacted the R3SET team and got involved to share R3SET with everyone."
