"Leave something on your plate."
Many of us were told by our parents that we had to clean our plates before leaving the dinner table. Perhaps we have taken this rule a little too much to heart! There is an older tradition that said it was more genteel NOT to finish every bite: "Leave something for Mr. Manners", is what some children were told. Practice NOT cleaning your plate; it will help you eat less in the short term and develop self-control in the long.
