When attending a party, offer to bring a plate. Arriving armed with chopped fresh veggies and a low-fat dip -- or any other low-calorie snack -- ensures that you'll have something to snack on without feeling guilty.
A fat lady stands in a bus. A young handsome man crashes into her unwillingly and sais: - I´m sorry I haven´t seen you... And the lady sais: - Oh you flatterer...
Another good joke:
"When I am frustrated I eat chocolate. But then I cannot slim down and I am so frustrated of it that I eat chocolate again..."
