This is so sad.
And good news for the Neighbors star! He's totes back on solid food!
Zac was spotted dropping into a convenience store and picked up a candy bar! OK, a health food bar- come on, you don't get THAT body by eating nougat all day!
But still, this totally means he can stop living off of protein shakes!
Oh, he also bought a vanilla protein shake. But hey, he's still a growing boy. Well, according to the That Awkward Moment trailer anyway! LOLz!
