I like 
A Tasty Torus
In the Back of a Black
and Tan Taurus 
Even in a Forest
Eating slow like a Tortoise 
A sweet treat
Quick to seek
Quick to delete
Quick to repeat
Waistline increase
Chance of diabetes
Rises like a flooded creek
Praying against this glaze
For days
Don’t want to graze
Just want to be saved

Hint: A doughnut is in the shape of a torus.
