Actor Dean Cain lost 35 lbs. after finding himself pre-diabetic and suffering from psoriatic arthritis at age 49, he tells PEOPLE. Topping out at 235 lbs. in January, Cain knew that he needed to make a change. “The last 10-15 years it has been extremely difficult to remain fit,” he says. “Of course, age plays a factor, but I have had psoriasis for almost 30 years, and about 10 years ago it evolved into psoriatic arthritis. As an ex-athete, I tried to tough it out for years, but definitely started losing that battle.” With a teenage son, Christopher, 16, getting into sports like MMA and Brazillian Ju-Jitsu, Cain, a former NFL player, tried to keep up, but his arthritis made it difficult. “I came with him to train, but was so injury-riddled and full of arthritis, all I could really do was walk on the treadmill, and stretch,” he says. “It sucked. I was the heaviest I’d ever been, 235 lbs, pre-diabetic and just getting worse. I was thinking, ‘Damn, this is where everything just goes down hill.’ ” Still in search of a solution after getting nowhere with his general doctor, Cain heard about the Beverly Hills Rejuvenation Center, were they ran more in-depth blood work that pointed to a solution. “I had some thyroid stuff that would never show up in a ‘normal’ blood panel, I was vitamin-D deficient and my body was just full of inflammation,” he says.

By the time Cain turned 50 on July 31, he felt like he was back in the game. “I’m just a shade over 200 lbs., playing basketball with my son, running, hiking, swimming, and feeling way better than I did at 40,” Cain says. “50 doesn’t feel so bad!”
