"I was eating 10 meals a day and drinking mass gainers," he said at the Hollywood premiere of Ted, his new comedy from Family Guy creator (and first-time director) Seth MacFarlane. "I was drinking my own. I created this line of supplements with GNC."

Really, 10 meals a day?!

"It was a lot of work," Wahlberg said. "A lot of getting up at 2 in the morning to eat another meal and I was still full from the meal at 10 o'clock."

Asked if he prefers being so big, he said, "You know, I like being able to change for parts, both physically and preparing mentally. It was a good time."

That goes for us, too—seeing Wahlberg shirtless is always a good time.
