Kim Zolciak Weight Loss: 'Don't Be Tardy' Star Lost 50 Pounds After Birthing Twins

Kim Zolciak dropped 50 pounds after welcoming her twins, Kaia and Kane.

After giving birth in Nov. 2013, the former Real Housewives of Atlanta star quickly got her body back, and in a new interview, she is sharing her weight loss secrets.

"I definitely think genetics play a role, that's number one," Zolciak, 36, told E! News on July 18. "Number two...I think with twins that every little morsel of food that you eat...goes to the baby. I made two human beings at the same time and I gained 50 pounds. Which I gained 50 pounds with KJ, so the twins, I think they took it from me."

During filming on The Real Housewives of Atlanta season three, Zolciak met Kroy Biermann (of the Atlanta Falcons) at a celebrity dance event. Right away, the pair hit it off and on Nov. 11, 2011, six months after welcoming their first son, Kroy Jagger, Zolciak and Biermann were married. Less than one year later, the couple welcomed their second son, Kash Kade. Then, on Nov. 25, 2013, twins Kaia and Kane arrived, bringing Zolciak and Biermann's kid count to six (Zolciak has two daughters from previous relationships).

Nine days after her twin's arrival, Zolciak made headlines when she posted a photo of her post-baby body, which appeared to be back to its pre-baby shape. However, Zolciak now claims she had a little help when it came to flattening her tummy.

"I do wear kind of like a homemade-type girdle after I had the babies, for six weeks, and I'm wrapped so damn tight for a period of time—and it makes your stomach flat as a board."
