  Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. Some people of different ages, form 12 to 83, were asked to have the test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

  The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, breads and milk before going to school, he will learn more quickly and listen more carefully in class.

  The results is opposite to what some people think. Having no breakfast will not help you lose weight(减肥). This is because people become so hungry at noon that they eat too muc for lunch. They will gain(增加) weight instead of losing it. You will lose more weight if you reduce your other meals.
