Nobody chooses to be a fat b*stard or a lardarse.

But not everybody wants to spend hours in the kitchen preparing "healthy" food, especially after a day's work.

I had a job with two hours drive each way, sat down all day, too tired to cook when I got back, too tired to do much except veg out in front of the box at night. I ballooned.

But the mortgage still had to be paid.

As people have said, it's complex and I don't see how you'd put it in a song - or interest people in the song if you did.
