JustJaredJr.com: Zac Efron lifts a full bag of snacks from Zen Food in Hollywood on Thursday afternoon (April 21).

The 23-year-old actor actually gave the service a full testimonial for their website — a pic of Zac showing off his muscular body is right on the front page!

Zac shared, “It was really easy to stick to your program, as all of the meals from Z.E.N. Foods were delicious and delivered fresh every day; they even delivered to me on location.”
