Second Guessed My Seconds

My First plate was quite yummy
But only half full of a tummy


To no surprise
That thoughts soon arise
That I should vie for some seconds

I know I'm quite paunchy and fat
And cannot eat this thing or that

What should I do?
I eat till I'm through
I'll need to buy a new pair of pants

To jilt plate number two is quite hard
To say no to sweets, cheesies, and lard

Pretend that I'm through
Is all one can do
But I know that going to get seconds

No longer thin, slim or prime
I wonder if wasting my time

To consider my seconds
I shouldn't I reckon
Second guessed a second too long
