Whitney Port is taking steps to change her lifestyle following concerns about her weight.

One week after The Hills alum first addressed comments from fans about being "too thin," sharing on her Instagram Stories her husband Tim Rosenman had also expressed similar sentiments, she opened up about her journey realizing she needed to focus on her health.

"At first, I didn't really want to address it," Port explained on the Aug. 1 episode of her With Whit podcast. "But in my head, I didn't think it was as big of a deal as it actually was—and I still don't really—but I do think that I'm clearly not eating enough and that how I look right now does not look healthy. It's not how I want to look."

The 38-year-old said that "getting on the scale was definitely an eye opener," adding, "I had no idea that I weighed as little as I did."

Port is already making the first move toward better health. As she put it: "There's a lot of self-reflection going on and I am aware of it and I think that's the first step."

For Port, one of the major aspects of shifting her lifestyle is her eating habits, recently opting for high-calorie foods like pizza, ice cream and French fries. But ultimately, she wants to eat "thoughtfully."

"I want to put the right things in my body and I also want to work out in a way that will build muscle," the reality star said. "So I'm on it, guys. Thank you for caring. Thank you for your love, for your support, for not saying something and then feeling comfortable saying something after I said something."

Port also slammed "salacious" reports about herself and her diet.

"Yes, I've never tried pasta before," she admitted, "but it has nothing to do with nutrition and that it can be a cause of weight gain. It's a pure texture thing."

Port also reflected on how her time on the MTV reality show, which aired between 2006 and 2010, affected her body image. "When I was on The Hills and I saw myself for the first time on TV, I was a little bit shocked," she said. "I was like, I feel a little pudgy and I would like to lose a little weight. And I think that was probably a self-reflection that normally people don't have or have to have. So it forced me to have to have it."

The reality star continued, "I think then that started maybe a slippery slope of some control issues—just control over what I look like, which I think it something that I should think about more. Because when I say that, it doesn't necessarily correlate to my weight. When I think about what I look like, I think about just being attractive, and I think I need to define what attractive means to me and then if those things are actually healthy."

In her recent Instagram Stories post, Port spoke about her overall relationship with food. "I eat to live, not the other way around," she said." But after stepping on the scale, it hit me. It's not something I strive for. I always feel hungry but I just don't know what to eat."

She continued, "It's not how I want to look or feel though. My excuses are that I'm too lazy to make feeding myself a priority or I'm too picky when it comes to taste and quality. Both are unacceptable and I don't want to set an unhealthy example. So I promised Timmy and I'll promise you that my health will always be a priority."
