Apart from the wheat in the bun, there's not an iota of plant matter in it that hasn't gone through an animal's metabolism first. The trees are safe from anyone who eats these; they won't even be able to climb one.

On the other hand, it surely isn't a burger for Jews. It breaks kosher in at least two important ways one can observe just at a casual glance.

It's kind-of like a one-serving meal. Drink water all day, have strawberries for breakfast and an apple-spinach salad for dinner (throw in some mandarin orange slices and don't peel the apple; it's better than it sounds), and you'll be fine!

To close, a song by Allen Sherman and Gilbert & Sullivan (sing Sherman's lyrics to the tune of "Little Buttercup" from HMS Pinafore):

I'm called Little Butterball
Dear Little Butterball
Though I could never tell why
My calories mount
My cholesterol count
Is as high as an elephant's eye

They told me to diet
I promised I'd try it
But somehow my weight would not budge
Each Metrecal cookie
To me tasted ookie
So I covered it with hot fudge

I ate watercresses
And other such messes
And pushed all my favorites aside
I said to the caterers
"No more mashed potaterers
Just baked and hash browned and french fried"

I sing this sad song
'Cause my diet went wrong
Though I honestly tried to pay heed
I don't care how high
Is an elephant's eye
But an elephant's rear I don't need
