Khloe Kardashian recently stunned fans when she shared a selfie revealing a slimmer figure. The "Keeping Up With The Kardashians" star appeared to have lost a lot of weight as she squeezes her tummy in a waist-trainer.

The 31-year old's rigorous workout regime has paid off if her recent Instagram selfie is any indication. Khloe's photo shows her wearing a body hugging suit and a waist-trainer as she poses in front of the mirror inside her dressing room. She captioned the shot, "Im obsessed with the gym but a little extra help never hurt nobody @waistgangsociety and @premadonna87 keep my waist snatched and posture perfect. Once you try it, you will become obsessed!!! Head over to whatsawaist.com the ONLY place to get your waist trainer!!!"

Her photo has since received over 771 likes and over 24 thousand comments from users who both complimented and criticized her slim waist. One Instagram user named alishahhhhhhh wrote that Khloe's body looks "so deformed" while another named melumadhay simply wrote, "waist goals."

According to Mirror UK, Khloe is taking some inspiration from her older sister Kim, who is also a fan of the waist-trainer. The soon-to-be-mother of two also shared a selfie on her Instagram page before where she's seen using a blue waist-trainer. The 34-year old captioned her photo, "I'm really obsessed with waist training! Thank you @premadonna87 for my new waist shapers! #whatsawaist."

Despite her tiny waist, Khloe is reportedly defying the warnings of using a waist-trainer. Matthew Griffin, owner of David Barton Gym, explained to Hollywood Life in an exclusive interview the harmful long-term effects the product can do to the human body.

"Our abs are an essential element to the stabilization of our entire body, especially our spines.  It is not only ineffective to depend on an outside force for a false sense of security, but downright dangerous depending on the exercise being performed," he said.

"If a corset is used to only mimic the shape of a toned midsection without actually using our muscles, the result is a false sense of strength and muscular engagement," Matthew explained to Hollywood Life.

Khloe has been hitting the gym lately to lose weight. On her cover interview for the Aug/Sep 2015 issue of Complex magazine, she revealed that she was once bullied over her weight and was called the "the fat, funny one" among her sisters Kim and Kourtney. But Khloe told the publication that back then she never thought of herself as fat or huge, just big boned.
