Kristin Cavallari ended up being "very thin" during her "really unhappy marriage"

Speaking on her 'Let's Be Honest with Kristin Cavallari' podcast, she explained: "I was very thin. I'll put it in perspective for you guys. I'm 5'3". I currently weigh 114 pounds. Filming 'Very Cavallari', I got down to 102, and I was eating the same amount of food that I'm eating now. The difference was I was so unhappy and so stressed out."

The former 'Hills' star - who previously alleged that the reason for the split was because Jay expected her to be a stay-at-home mom and not work - explained that she sometimes looks back on photographs from that time and wonders how she ever manged to deal with having "so much on [her] plate" emotionally all at the same time.

She said: "I look back at photos from that time period and I am like, 'Holy s**t.' I was rail f****** thin. I was skin and bones. I looked like s***. I think I look so much better now. And you guys, that was just stress. That was being in a really unhappy marriage, quite honestly. Literally, I was so unhappy, and I had way too much on my plate."

But now, Kristin is dating TikTok star Mark Estes and admitted that she is doing "so much for " to take care of both her physical and mental health.

She said: "Now, I'm just taking care of myself in so many more ways too. I work out with a trainer one day a week, lifting really heavy weight. And then I usually work out three to four [other] times. So I work out four to five times a week, one time with a trainer. I lift weights on my own two to three more times... I think with the gym, it's consistency.
