In an interview with GQ, WWE RAW superstar Bill Goldberg discussed a variety of topics, including how he stays in shape at 50 years old.

“When you’re 50 years old and you’re putting your underwear on in front of millions of people and you used to be me – lets just say that I’ve cleaned up my diet quite a bit. I didn’t use to be as strict with my fat intake.

I mean, I didn’t even know what ‘Gluten-free’ was then. I ate everything that I saw back then. And it didn’t matter because I was younger and my metabolism was even faster. I’ve always been blessed with a very fast metabolism. Which, again, is a blessing and a curse when you’re trying to gain weight and get into cardio shape.”
