Everything You Need To Know About Kim Kardashian's Waist-Shaper

The beautifully curvy Kim K. shared a new weight loss method on Instagram.

In her continuing efforts to slim down, Kim Kardashian West has discovered a new gym trick, and she shared a photo of it on Thursday afternoon (August 21). The reality superstar famed for her curves revealed she's now employing the "waist shaping" method, which typically involves wearing a body-restricting corset for several hours a day.

Kim updated her Instagram rocking a white tank, matching leggings and an impossibly tiny blue corset, with the caption "#hourglass #waisttraining #nophotoshopnecessary," and a shout-out to Whats A Waist creator and CEO Premadonna.

Fans were quick to flock to Kim's IG post, with many eager to buy the product and watch the inches melt away -- "we need that waist trainer!" and "we were just talking about waist training!" were common sentiments.

This method is nothing new. Corsets have been used by women to shape and contour their bodies for centuries, but what may be overlooked are the possible health risks.

In a June interview with the Power 105.1 Breakfast Club, Premadonna joined the New York City radio hosts to tout the magic of her miracle product. When asked how it works, the Miami rapper and entrepreneur explained that the wearer doesn't have to diet or work out and "[the garment] actually reconstructs the body. It makes you sweat and gives you that actual, hmm -- like you're working out. I can't explain it."

This controversial fad went mainstream last year when actress Jessica Alba revealed that she'd worn a double-corset for months, day and night, to reverse the effects of pregnancy on her body. However, Alba herself admitted to The Edit, "It was brutal; it’s not for everyone."

The problem with shaping garments is that they can do serious damage on the way to giving the wearer the desired "hourglass" shape, according to experts like bariatric physician Jyotindra Shah, M.D., who spoke to Huffington Post last October about the negative effects of girdles on women's health, including bruising to your internal organs.

"Putting this corset tight on the body could bruise your skin," Shah told the site. "People might put it so tight that the liver, spleen and kidneys could get bruised."

Other shapewear, like Spanx and skinny jeans, have come under fire for contributing to a rise in health problems. Dr. Orly Avitzur, a neurologist and medical advisor for Consumer Reports, told that she's seen a growing number of women experience digestive and nerve problems as a result of wearing the garments. "It's a trend even among thin teen athletes to wear one or even two Spanx all day," Avitzur said.

The safest route anyone can take to lose body fat and recompose their body is through a combination of a healthy, whole-food diet, complemented by a consistent exercise regimen with a focus on strength and resistance training. Instead of aiming to reshape your bone structure, work to enhance your natural shape!

We’re sure Kim’s using it safely.
