"Piggy" is a somewhat childish, cute way of meaning "pig." In slang, it may refer to someone who is chubby or enjoys eating, but in this context it literally means a young or baby "pig," which may also be called "piglet." Ex: I'm such a piggy. I need to stop snacking. Ex: I need to stop being a pig. I need to start working out.
