There is no denying that Shinedown's Brent Smith is one of rock's best singers, but sometimes in the past, like a lot of other rock stars, he has made some poor decisions  Now his act seems to be cleaned up, and he is also looking as good as he ever has after losing 70 pounds... Here is how he did it. 

In 2011, Smith weighed 222 pounds and was really out of shape. He made a decision to get in shape when he saw the Insanity infomercial late one night with Shaun T., Brent not only lost the excess weight but also went from 36% to 12% body fat and is now in the best shape of his life!

Smith has completed Insanity four or five times and has even encouraged fellow Shinedown band members to join in well on tour.

According to The Pulse Of Radio, Smith opened up in a recent interview with the Los Angeles Times about his four-year struggle with substance abuse that ended with him quitting cocaine, painkillers and alcohol and losing 70 pounds in the process. Smith said that the final straws were a warning from his girlfriend and an insult about his girth on national television. Smith explained, "I've toured for over 12 years, and for the first two records I was addicted to cocaine, OxyContin and alcohol. The coke and Oxy kept my weight down. But for the third album I quit the opiates and started to crave sugar. I was still drinking a lot of alcohol and started to pack on the pounds."

Shinedown appeared on the "Today" show in 2009, where host Kathie Lee Gifford said, "At first I thought he was Meat Loaf."

Smith recalled, "It really stung. I'm a fan of Meat Loaf but she wasn't talking about a musical comparison. My heart kind of fell on the ground — it was like the performance didn't even matter."

Next was an ultimatum from his girlfriend, with Smith revealing, "Teresa sat me down on the first of November last year and said, 'Listen to me, I love you and I'm not going anywhere, but this lifestyle that you're leading is not going to work."

Teresa sent Smith, who weighed 222 pounds at the time, to a trainer. He added, "I felt like I'd been in a death spiral, and I realized I needed to be healthy and strong for my family. I have a four-year-old boy, and he was a huge motivation, and so were the fans. I had an epiphany working out with my trainer that day, and I haven't had a drink since."
