I ate 10 meals a day for film role: Mark Wahlberg

The 41-year-old actor plays bodybuilder Daniel Lugo in the upcoming film. He followed a 24-hour plan and even woke up at various times throughout the night to eat his food fix and drink his muscle-building shakes, reported E! online.

"I was eating 10 meals a day and drinking mass gainers. I was drinking my own. I created this line of supplements with (retail chain) GNC. It was a lot of work. A lot of getting up at 2 a.M. To eat another meal and I was still full from the meal at 10 o'clock," he said.

"You know, I like being able to change for parts, both physically and preparing mentally. It was a good time," he added.
