Some people don’t mind being fat. Other people can keep slim 
(苗条) without any effort. But a lot of people do put on too much weight and don’t like it. The question is, what can thy do about it?
Some believe exercise can be helpful. But the trouble is that it only makes you want to eat more. You might sweat out a couple of pounds playing tennis or climbing a mountain, but you put it all back on again with a big steak or bread and jam.
A helpful way is food choosing. But what sort of food should you choose? Some believe that the less they eat, the slimmer they will be. They don’t eat anything until they become weak with hunger. Some stick to milk and bananas. You’ll find you need a lot of bananas, and unless you live where they grow, they aren’t cheap. Another says that if you eat things like hard-boiled eggs, and apples with their skins on which are hard for your stomach to digest (消化), the more you eat, the thinner you get. This is because you use up the fat in your body to get the energy to digest the food.
For most of us these methods are too extreme (极端的). The simplest way is just to cut down on the carbohydrates (糖
类) that means not eating bread, potatoes, cakes, sugar, rice, and so on and eating anything else you like. It’s straight forward and often quite effective.
Still others like to be more scientific. They are calorie countries. They get a table, which tells them that, for example, 100 grams of roast let of lamb gives you 330 calories and a 50 gram helping of Yokshire pudding gives you 130 calories.

In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

Good health is the most valuable thing a person can have, but one cannot take good health for granted（认为……理所当然）. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
