Carlos Orosco has managed to shed more than half his weight in an incredible transformation story.

Orosco once weighed 651lbs, and as a result of his size was told his life expectancy "was really uncertain".  Three years ago he was struggling with a range of health issues, such as ulcers in his legs, extreme gout, high blood pressure, sleep apnea and cellulitis, a bacterial infection causing painful swelling.

Carlos met with a bariatric surgeon to discuss weight loss surgeries, who told him that he would need to demonstrate his eating habits and set himself up for life post-op before that unless he could undergo weight loss surgery.

So Carlos decided to turn his life around for the sake of himself and his loved ones. He cut junk food out of his life and began walking regularly, and ended up losing an incredible 100 lbs in just six months. He underwent weight loss surgery surgery in 2016, but his newfound passion for fitness remained, and in 2017 he even completed a marathon!

Commenting on his weight loss in a recent interview with PEOPLE, Carlos stated: "I knew that my sister and brother in-law were expecting their first child and that I was going to be an uncle soon and I needed to get healthy now. I needed to be around for a long time to come, to be able to experience my niece growing up. I realised that I was being selfish, living the way that I had been for so long."

He continued: "A lot of people see the before and after, and some see having a bariatric procedure as an easy way to solve the weight issue, but in actuality, it is the hardest thing that I have ever done in my life, and have to work on every day. Some people don’t realize or understand the mental and physical sacrifice, and the challenges that are associated with this process."

He added: "You need to have the right people in your corner, the right people on your team. These people need to be people who know you, understand what you are going through, hold you accountable, listen to you, tell you what you need to hear, not just what you want to hear. In my experience, having these people, whether they be friends, or family, has been vital to my success."

Carlos says that his body image and self-confidence is at an all-time-high after dropping an incredible 475 lbs.
