　　If you have to miss a meal a day(or if you want to do so)，which meal will cause you fewest health problems if you don’t eat it?If you have to make a decision of this type，most people(especially very busy people)will choose to skip breakfast．

　　However，many experts in the field of health consider breakfast(the meal which “break”you “fast”and which started the night before)to be the most important meal of the day．If we eat a good breakfast，they say，we will have the energy and nutrients(营养)we need to begin our working day with vigor(活力)and hopeful with good honor．However，many people skip breakfast or substitute(代替)a donut or a cup of coffee for a well-balanced meal．What happens if we ignore the importance of breakfast?

　　One recent study conducted in the United States tested a large number of people．Participants(参加者)included both males and females who ranged in age from 12 to 83．During the experiments，these people were given a variety of breakfasts，and sometimes，they have to skip breakfast completely．Special tests，including blood tests and endurance(耐力)tests，were set up to analyze(分析)how well the participants bodies functioned when they had eaten a certain kind of breakfast．

　　The results showed that if a person eats an adequate breakfast，he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast．This fact appears to be especially true if a person’s work involves mental activities．The study showed that if school-children eat fruit，eggs，bread and milk before going to school，they will learn more quickly and will be able to concentrate(集中)on their lessons for a longer period of time than if their breakfast is inadequate．

　　The study also showed that contrary to what people believe．If you skip breakfast，you will not lose weight．This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing．So remember，if you want to lose weight，skipping breakfast will not help you．You will probably lose more weight if you reduce your other meals．
