We have calculated the total fossil energy equivalent of the food calories saved by reducing the present degree of overweight (2.3 billion pounds for the adult United States population) to optimum body weight and the annual fossil energy reduction once all Americans reached their optimum weight. The energy saved by dieting to reach optimal weight is equivalent to 1.3 billion gallons of gasoline and the annual energy savings would more than supply the annual residential electrical demands of Boston, Chicago, San Francisco, and Washington, DC.
我们已经计算出,将目前的超重程度(美国成年人口超重23亿磅)降低到最佳体重所节省的食物卡路里的总化石能源当量,以及一旦所有美国人达到最佳体重后的年度化石能源减少量。通过节食达到最佳体重所节省的能源相当于13亿加仑汽油,而每年节省的能源将足以满足波士顿、芝加哥、旧金山和华盛顿特区每年的住宅用电需求。
