You wouldn't know it by looking at him today, but there was a period not too long ago that Shinedown singer Brent Smith was struggling with both drug and alcohol addiction, as well as weight issues. Part of the reason Smith is built as well as he is these days is due to his newfound commitment to his health, and he discussed his transformation with the Los Angeles Times.

Smith says, "The weight came on about four years ago. I've toured for over 12 years and for the first two records I was doing tons of shows all the time. And for those 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 opiates and started to crave sugar. I was still drinking a lot of alcohol and started to pack on the pounds."

The singer says one of the big wake-up calls was when he made an appearance on the 'Today' show in 2009 and Kathie Lee Gifford stated that she mistook him for Meat Loaf. The vocalist says, "It really stung. I'm a fan of Meat Loaf, but she wasn't talking about a musical comparison. It was national television and my heart kind of fell on the ground. I'm not trying to be disrespectful to Meat Loaf at all because I'm a fan, but here I am barely 30 years old and that's the one thing that she says. It was like the performance didn't even matter."

In the time since, Smith has found a trainer and made a commitment to live healthier for his family. He explained, "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 … and I haven't had a drink since."

Since he began his workout regimen, the singer has dropped almost 70 pounds. To read more about Smith's weight loss journey, check out his Los Angeles Times interview here.
