Bethenny Frankel is getting real about how she remains healthy and active.

In a new TikTok video, the former Real Housewives of New York City star answered a fan’s question about how she’s able to “stay so thin.”

“I get asked this all the time. I don’t exercise. I do what I can, when I can,” the 51-year-old Skinnygirl founder began. “I’ll snowboard if I can, I’ll surf if I can. I’ll walk on the beach… but I choose sleep first. Sleep is the number one priority and being happy is the number one priority.”

“I was probably 20 lbs. heavier in my 30s and I was always on a diet,” Frankel admitted, adding that she no longer believes in the idea of exercising to work off calories consumed.

“So I eat what I want, and I don’t ever binge. I don’t workout and I don’t do weights,” the reality star continued. “I believe in balance. I believe in sleep, I believe in living, I believe in french fries, I believe in alcohol, and I believe in not being crazy.”

“The crazier you get, the worse it gets for you. And as you get older, you realize the zero f—s lifestyle works better,” Frankel added.

She explained that she goes for walks and does other activities simply because she wants to and enjoys them, and said anyone who feels “shackled and imprisoned by dieting” is going to be miserable.

Frankel has been promoting body positivity in the last few years. Last year, she shared a mirror selfie on Instagram posing in her shapewear with an encouraging message to her followers about why she’s not a fan of filters.

“If I were a ‘filterer’ I would have gotten rid of my lines and my dark circles, but this is me at 50. #zeroglam #zerofilter,” she began the caption.

“Why do I mention this all the time? Because I think it’s important for young women to know that being flawed is truthful and real, and that filtering yourself into someone fictitious is actually damaging to girls’ and women’s self esteem,” Frankel continued. “It’s courageous and beautiful to be real at any age.”

“I realize that fake and filtered sells,” she added, “but I’m happy over here with my followers who appreciate the difference. ❤️ #NationalShapewearDay @skinnygirlbrand shapewear.”
