Beef! Beef! Beef! Beef! Beef!?

Okay, so I'm a 13 year old male. A tiny bit stout, but not herp derp blubberfall or anything. In the last two days, I have had an acute craving for beef, chicken, and fish. I've hardly eaten any junk food but engorged myself on more beef than I've ever eaten in the last three days- is this a growth spurt thing?
