减掉的体重没有去任何地方。当人体需要能量时,体重就消耗了。假设人体是一台机器。食物是维持这台机器运转的燃料。人们从食物中获取的能量数是以卡路里计算的。人们必须食用一定数量的卡路里来维持机器(人体)有效的运转。如果摄入大量多余的卡路里,机器就把多余的燃料作为脂肪储存起来。如果摄入的卡路里太少,机器就将储存的脂肪转变成能量,这时,体重就减掉了。 Lost weight did not go anywhere. When the body needs energy, it loses weight. Assume that the human body is a machine. Food is the fuel that keeps the machine running. The amount of energy people get from food is calculated in calories. People must eat a certain amount of calories to maintain the effective operation of the machine (human body). If you consume a lot of extra calories, the machine stores the excess fuel as fat. If the calorie intake is too low, the machine will convert the stored fat into energy, at which time the weight will be lost.
