"Your organs needs room!" wellness expert and founder of , Shanna Israel, exclusively told Radar.
"You don’t want to create health issues due to ill fitting garments. Like any diet or practice, if you push your body the wrong way or force it into compromising positions there can be negative effects."
Waist training involves wearing a corset-like device that will allow you to "instantly look 2-3 sizes slimmer" without any exercise or surgery, but experts suggest it's actually moving the lower ribs in an unnatural way, which is why your waist appears smaller.
And Kim isn't the only Kardashian who loves a corset.
In May her sister Khloe revealed her tiny waist following a 30-pound weight loss with an Instagram picture captioned:
"I love my waist trainer from @premadonna87!!!! Miss @blacchyna has me obsessed!!! Who doesn't love to feel tight and right?!? #whatsawaist #waistgang #Fitness #GetItRight."
"Tight clothes can impact your organs and possibly create cramping or breathing issues," Israel warns.
"I know women in other countries wear tight corset like wraps to shrink their stomachs after pregnancy… I believe results differ based on each persons experience . Also, when looking at the success stories of others keep in mind you don’t know what else they are doing to lose weight. It could be a combination of factors."
