Looking good, Kim Zolciak-Biermann!

The 37-year-old reality star used Instagram to show off a picture of her flat stomach and update her fans on the status of her bloating on Wednesday.

After a recent family vacation, Kim has been using Flat Tummy Tea, and she shared this mirror selfie to explain more about it.

"Week two update of @flattummytea, Ive got lots of questions about it," she wrote in the caption. "Don't get it twisted girls this isn't a weight loss tea, it's main game is kicking bloating which so far so good!"

She also makes clear that it's not just tea that she's drinking to help keep her body in shape.

"Headed downstairs to workout (let's be honest, there is no tea that's going to help you enough to stop working out) Are you guys trying it too, what y'all thinking of it so far?" she asked her 1.9 million followers.

Before she posted this snap, she also promoted the tea bags earlier in the week.

"If this works it'll be a keeper for sure!" she wrote.

Kim is not a stranger to trying out new things when it comes to weight loss.

She also used a waist trainer in June 2015 and claimed she lost four inches as a result of wearing the tight corset.

In addition to getting her body in shape, Kim has been in the lab as she is gearing up to launch a skincare line.

Just a couple of weeks ago, she posted a video in a lab coat on Instagram.
