As we've all seen, Chris Pratt got totally ripped for his role in the upcoming Marvel movie Guardians of the Galaxy.
All the more impressive, of course, considering how he had gained 60 pounds to shoot the new Vince Vaughn film Delivery Man.
His secret to shedding the the excess pounds?
"I cut beer out," the 34-year-old actor told Jay Leno during an appearance on Wednesday's Tonight Show. "I didn't drink for seven or eight months, which was really not that difficult for me."
However, Pratt admitted that it did impact more than just his weight.
