What has happened in the United States, and now more and more throughout the world, is that people have not been conscious of the nutritional value of the foods they eat and have consumed more than is necessary, resulting in a large population of people who are
overweight. This is mostly due to the great availability of food and the constant advertisement of it. When full course meals are available in a gas station and you can seldom watch TV without a barrage of suggestions to buy and eat unhealthy foods, it can be hard to
lose weight, or maintain a healthy weight.
