Kim Zolciak Reveals How She Lost 50 Pounds Of Baby Weight

Kim Zolciak stunned fans when she revealed a photo of her post-baby body just nine days after giving birth to twins, Kane and Kaia. In the photo, Zolciak looked as if she'd never been pregnant at all, which left fans wondering how she slimmed down so fast. In a new interview, Zolciak is telling all about her weight loss.

"I'm ready to put my bikini back on!" Zolciak told Life & Style on Jan. 30 for their new issue.

After gaining what she claimed to be "50 pounds with the twins," Zolciak is now "between a size 2 and a size 4. I won't get on the scale, but all my clothes fit again!"

In addition to working out regularly with her football player husband, Kroy Biermann, Zolciak has also enlisted the help of diet supplement Xenadrine to speed up the process.

"I take Xenadrine for energy to work out and do an hour of cardio each day."

Following the birth of her fourth son, Kash Kade, Zolciak appeared in the covers of Life & Style, showing off a 30 pound weight loss just fourth months after his birth. At the time, she credited hectic life with keeping her slim.

"I've lost 30 pounds," the reality star revealed. "I'm only 5 to 8 pounds above my weight before I got pregnant. I never sit on the couch. I think breast-feeding helped me lose some weight, and I was really busy as soon as I got home with Kash. I went straight into filming my spin-off show, Don't Be Tardy..., and I'm sure that helped. I just never sat still!"

Also helping her in the weight loss department was her diet.

"I don't eat red meat or pork or much dairy, and I always eat in moderation," she told the magazine. "I'm a size 4 right now, and my goal is to get down to a size 2. I'm accepting that I'm going to have to hit the gym - my girls [Brielle, 15, and Arianna, 11] laugh and say there's no chance, but I really think I'm going to have to."
