The bulge in your gut’s an embarrassment, but
You just can’t decide on which diet to use—
The one with all carbs or the no-fats-at-all.
You set a date certain by which you must choose.
 
The date has arrived and you’ve not made a start.
The fat’s hanging over. Your trousers won’t fit.
You do what you promised you’d do in this case:
You take out a knife and you slice off a bit.
