Question

Probably over half of Americans are overweight in different degrees, a fact most newcomers quickly notice. This is because of a diet that is high in fat, sugar, and salt. In the South, much food is fried or flavored with fat.

You will see many television commercials about dieting and exercising, indicating the serious concern people have about their weight problems. Many Americans lose weight by restricted diets and much exercise as obesity is considered harmful to good health, appearance, and longevity(长寿).

Many Americans can afford to eat well and have jobs that do not offer much opportunity for exercise. The possession of cars also limits the amount of exercise most people get. It is therefore easy for Americans to put on weight, and many newcomers have found that the good food and lack of exercise can add pounds on them, too.

Generally, Americans hate being overweight, and some people—especially women and teenage girls—suffer from eating disorders. These disorders can become health-threatening or ever life-threatening and often require psychiatric treatment(精神病治疗). Even those who do not suffer from eating disorders often eat carefully to control their weight.
