Needing to shed a bit of weight, a married couple went on a diet that had specific recipes for each meal of the day.
They followed the instructions extremely closely, dividing the finished recipe in half for their individual portions. They both felt terrific and thought the diet was wonderful; they had never felt better, nor did they ever feel hungry.
As time progressed, the couple realised that they were, in fact, putting on weight and not losing it. They decided that they ought to check the detail of the recipes just one more time. It was then that they found their error.
There, in small print the couple saw, to their horror: “Serves 6.”
