As someone who has struggled with his weight his entire life, I know how difficult it can be to first lose weight, and then maintain that weight loss longterm.

However, this video shows someone undergoing an incredible transformation over the course of 12 months, losing almost 200 pounds in just 365 days.

Vance Hinds was inspired to embark on his weight loss journey by comedian Bert Kreischer, who took the sober for October challenge.

One year later, and Hinds had dropped from 475 pounds to 277 pounds. He’s still a large guy, but his incredible effort has probably added years to his life. And what an achievement.
