We know the effect calories have on your body. For each pound of weight that your body carries,it takes about 12 calories per pound per day to keep it alive. If you weigh 150 pounds, you therefore need about 1 , 800 calories per day to keep yourself alive and maintain that same weight.

If you were to eat more than 1 , 800 calories per day,the surplus(剩余) turns into fat. It takes about 3,600 excess(过量的) calories to make a pound of fat.

  Let's say that you were to eat,on average, 2,000 calories per day. That extra 200 calories per day is going to turn into fat. However, you will eventually hit a point of equilibrium(平衡, 均衡) because as you gain weight, you need more calories to maintain that weight. So,a person eating an average of 2,000 calories per day will hit equilibrium at (2,000/12) 166. 67 pounds.

  So let's say that you eat,on average, 2 , 000 calories per day and reach equilibrium at 166 pounds. Then you go on a crash diet where you eat only 1 , 000 calories per day for 60 days. You lose 16 pounds and reach your target weight of 150 pounds. But then you go right back to eating 2 , 000 calories per day again. The graph below shows your eating pattern before, during and after the diet:

Note that the graph assumes that you,like most people, eat a random(无计划的) number of calories per day. Some days you are "good" and eat less,and some days you are "bad" and eat more,but the assumption is that it averages out to 2, 000 calories per day over the long run.

This graph shows what happens to your weight before ,during and after the diet :

  

 The diet really takes the weight off. But the weight comes right back when you return to your "normal" eating pattern. The weight appears to come back so quickly because when you are at your lightest,you tend to gain more weight each day. The lighter you are,the fewer calo?ries you need. If you only need 1,500 calories per day and you're eating 2,000,you're going to gain weight faster than if you need 1,800 and you're eating 2,000.

There are only two ways to keep the weight off :

Change your overall eating pattern so that you take in,on average,fewer calories than be?fore you go on the diet.

Start exercising so that you "burn" the extra calories you take in.

The best course of action is a combination of these two choices.

  You are what you eat and fats are a main food for Asia's fast-food generation. Dr. Chwang, director of the Department of Food Nutrition,says children are consuming more meat and soft drinks. This is a thorough departure from the traditional diet of vegetables and rice and little meat. "They like big pieces of fried meat with a soft drink. So although they may eat the same volume of food,their calorie intake(卡路里摄入量) has increased. Now about 40 to 45 percent of their calories come from fat”,says Chwang.

 Although on the whole Asians tend towards thinness,culture―namely Asians' hospitality (好客) 一is the reason for the fatness of today's generation, according to Chwang. " Asian people love food," she says. "Eating and drinking are important social and family functions.” In the past,however, big meals were only hosted on special occasions as people were more careful with money. In today's climate of wealth and remarkable consumption, 10-course meals are no longer reserved for significant occasions.

 More than anyone else,Children are on the receiving end of their parents' improved cir?cumstances. "In the past,people had four or more children―now,they have one or two,so they tend to spoil them," says Chwang. "The easiest way is to give them quality food. Parents think feeding them well is showing their love. They feel bad when their children look thin.”

 When describing the physical condition of most overweight Asian children, Chwang says, "There is a clear relationship between fatness and indoor play. Children get fat because they don't move,and eventually, they don't want to move because they are fat.”

 Thanks to technology, a growing army of children prefer video games to old outdoor sports. " What do children do when watching TV or sitting in front of the computer playing video games? They eat chocolate and drink Coke," says Chwang.

It was the end of my first day as a waitress in a busy New York restaurant. My cap had gone away,and my feet1      The loaded plates I carried 2      to be heavier and heavier. Tired and discouraged,I didn't seem able to do anything 3      . As I made out a check for a family with several children who had changed their ice-cream 4      a dozen times,I was ready to stop. Then the father 5      at me as he handed me my tip. "Well done," he said, "you've 6      us really well.”Suddenly my tiredness 7      I smiled back,and later, when the man?ager asked me how I'd like my first day,I said, " 8      !" Those few words of praise had 9      everything. Praise is like 10      to the human spirit;we cannot flower and grow without it. And 11      ,while most of us are only too 12      to apply(应用) to others the cold wind of criticism(批评) ,we are 13      to give our fellows the warm sunshine of praise. Why― when one word of praise can bring such 14      

It's strange how chary(吝啬) we are about praising. Perhaps it's because 15      of us know how to accept it. It's 16      rewarding(值得做的) to give praise in areas in which

17      generally goes unnoticed or unmentioned. An artist gets admired for a glorious picture,

a cook for a 18      meal. But do you ever tell your laundry manager how pleased you are when the shirts are 19      just right? In fact,to give praise 20      nothing but a moment's thought and a moment's effort.
