Diet starts Monday

Time to change myself once more
It's my mantra every Sunday
Be good with food and have less wine
This always starts on Monday

Commence with gentle exercise
And eat a smaller ration
By Tuesday this is going well
I'm full of strength and passion

It's Wednesday I am feeling weak
I want to drink some claret
I tell myself to carry on
So instead I eat a carrot

I put myself to bed that night
Hoping not to suffer
Tomorrow is another day
Of course I'll be much tougher

By Thursday I am back on track
I'm feeling rather dandy
I force myself to eat less snacks
And have a little brandy

By Friday it is getting tough
I'm feeling so much weaker
I pour a glass of cold crisp wine
And then fill another beaker

Come Saturday I am off the plan
I've gelled into my sofa
I fill my face with tasty treats
And turn in to a loafer

The sabbath day I carry on
I may as well keep eating
Hereafter I will start again
And do it without cheating
