Michelle Duggar opens up about her past struggle with body image in a new episode of "19 Kids and Counting" that airs Tuesday night.

"Before I came to know the Lord, I had been struggling in my self-worth, just feeling like I needed to measure up with all of my friends around me," the 48-year-old family matriarch reveals. "I just really began to have a wrong view of who I was and felt like I gained weight so easily."

The mom of 19 adds, "I ended up starting a bad habit of making myself get sick after I would eat, especially if I had more food than I felt like I should eat. And it was destructive for my health and my life."

Duggar now tries to set a positive example for her nine daughters.

"I think all girls probably struggle with the same body issues. The struggle is going to be there," she says. "How do you deal with the struggle? And I just talk with my kids — my girls, my boys — and I'm honest with them about the things that I struggled with."

"Life is too short to never have a chocolate chip cookie. But you need to be wise in how you do that."

Last year, Duggar told People that she's always been up-front with her children about having battled bulimia as a teen.

"I have been open with my struggles with the kids before," she said. "We talk about how God has brought us out of different things along life's way."

The "19 Kids and Counting" episode airs tonight at 9:30 p.m.
