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

The rules 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, bread and milk before going to school, he or she will learn more quickly and listen more carefully in class.

The result is opposite to what some people think. Having no breakfast will not help them lose weight. This is because they are so hungry at noon that eat too much for lunch. They will gain weight instead of losing it. You will lose weight if you reduce your other meals.
