Americans are getting fat. A new study says that most Americans are too fat. Is that true? Look at the people around you. Are most of them fat? Are most of them thin? Or are most of them in between? Many fat people get sick. They die young. Doctors say these people can live longer. They must eat more fruits and vegetables. They must eat less meat. They must eat more fish. They must eat less fried food. They must not eat at fast food restaurants. No more cheeseburgers, and no more French fries. They must eat less bread and less pasta. If they eat less, they will weigh less. But Americans must also exercise. They must walk more. They don't have to run or jog. They don't have to climb stairs. All they have to do is walk. Just walk 30 minutes a day. Is that hard to do? Eat less. Walk more. Live longer. It sounds easy. But people love to eat. Eating is fun. Food is delicious. So it's not easy to eat less. Try to do it. It's hard to do.
