My 600-lb Life star Nikki Webster, Close-up

Plenty of reality shows feature dramatic transformations, but few chronicle the intense metamorphoses that are documented on the popular TLC program My 600-lb Life. Since its inception in 2012, dozens of men and women have had their lives changed, thanks to the intervention of Dr. Younan Nowzaradan. Based in Houston, Texas, Nowzaraden performs weight loss surgery on patients who oftentimes are desperate to improve their quality of life before it’s too late. And while the journey is never easy for these people, it’s worth it to be able to reclaim their lives and accomplish goals they had previously given up on.

Some of these brave souls have gone on to become social media stars, thanks to their reality television fame. That gives us additional access into their lives, allowing us to keep up on what happens — even after their follow-up segments have aired. So without further ado, here’s the skinny on some of the most popular stars from My 600-lb Life. You won’t believe how amazing they look today!
