They're correct that what the Kardashians are doing is BS - but, speaking as somebody who is a fan of body modification and knows women who do the "heavier" more serious form of waist training, I have to laugh at this article. First, some terminology: "waist training" doesn't refer to just lacing up a corset. It means a VERY long term (usually years long) process of tight lacing a corset, usually every single day (or close to it). That process will, very gradually, cause the natural fat deposits around the waist to shift up and down and will create a smaller waist over time. Again, this can take years to achieve. It is not done out of a desire for weight loss - it's aesthetic, much like what bodybuilders do. It also won't work on a fat, because their natural waistlines are so buried under excessive fat tissue that real waist training is simply not possible for them - in order to train your waist, you need a waistline to work with in the first place!  The Kardashians promote what are essentially girdles - they may hold you in a little and be snug and maybe that's enjoyable for some people, but it's not waist training in any sense of the word. It bugs me.
