Counting calories

I am counting calories and it's very, very tough
Cos 1 square of chocolate, isn't nearly enough
Everything I love, everything I adore
Are always so full of calories, I can't have them any more
Crisps and chocolate cake, cream buns and apple pie
Smothered in chocolate ice cream, just a taste I'd like to try
Fish and chips or pizza, I now have to say no
And over to the salad bar for rabbit food I now go
I could have a chocolate bar, if I ate nothing else all day
And a hot chocolate fudge cake, well that would be 2 days I'd say
But on a more positive note, my weight is going down
Even if my face, does nothing now but frown
another bonus to, is my maths has now improved
All this to lose weight and have my  knees removed
