    Not all Americans are physically fit, or even try to be. The overall population is becoming heavier, due to poor eating habits and a sedentary lifestyle. Some studies estimate that less than half of Americans exercise in their leisure time. Experts say that it is not because Americans "don’t know what’s good for them" — they just don’t do it. Compared to the beginning of the 1980s, three quarters of Americans in the 1990s say that physical fitness is more important to them now than it was then. But the National Center for Health Statistics reports that the number of people who are at least 20 percent over their desirable weight has risen from one in four to one in three Americans.
    Newspapers and magazines are full of information on nutrition and poor diet. Television news programs urge people to eat more vegetables and warn of the dangers of high-fat diets and high cholesterol levels — particularly heart disease and certain types of cancer. Since 1994 the government has required uniform labeling so that consumers can compare the fat and calories in the food they buy. Grocery stores are full of low-fat or fat-free cookies, crackers, bread, milk, margarine, mayonnaise, and even potato chips. Many Americans have switched to skim milk, but they still buy fancy, fat-rich ice cream. More than half of Americans say that they pay attention to the nutritional content of the food they eat, but they also say they eat what they really want whenever they feel like it.
    Experts say that it is a combination of social, cultural, and psychological factors that determine how people eat. A Newsweek article on America’s weight problems refers to "the culture of over-indulgence seemingly ingrained in American life. The land of plenty seems destined to include plenty of pounds as well," they conclude. Part of the problem is that Americans eat larger portions and often go back for second helpings, in contrast to how much people eat in many other countries. Another factor is Americans’ love of fast food. Some estimates are that 50% of Americans eat pizza once every two weeks, a percentage that is no doubt quite a bit higher among high school and college students. Americans are consuming more and more hamburgers, French fries, and soft drinks at restaurants, not only because they like them but also because these foods are often the cheapest items on the menu. Another significant factor is Americans’ busy lifestyle. Since so many women are working, families are eating a lot of fast food, frozen dinners, and restaurant "takeout". Some experts believe that Americans have really lost control of their eating; it is not possible to limit fat and calories when they eat so much restaurant and packaged food. It takes time to prepare fresh vegetables and fish; stopping at KFC(Kentucky Fried Chicken)on the way home from work is a much faster alternative. Often American families eat "on the run" instead of sitting down at the table together.
