"The banquet is in the first bite." Taking this adage to heart will help you enjoy your food and eat more slowly. No other bite will taste as good as the first, and every subsequent bite will progressively diminish in satisfaction. Economists call this the law of diminishing marginal utility, and it argues for savoring the first few bites and stopping sooner than you otherwise might. For as you go on, you'll be getting more calories, but not necessarily more pleasure.
