Very nice. You'd obviously have to hear it sung to music in order to fully appreciate it. About the only change I'd make is with this verse:

You can have your cake and eat it, its official
On my dessert plate you always serve up something special
Here’s to gaining weight my hungers satisfies your true potential
There’s no delay we feed like there’s no tomorrow
Oh yes that’s right

... cleverly thought out, but out of place with the rest of the tune and a little corny. It brings you out of the moment and makes you think about the writer trying to come up with something clever instead of conveying a real emotion.

Just my own opinion though.
