    Many schools now serve breakfast as well as lunch. A lot of kids who take part can end up eating two breakfasts one at home and one at school. People are concerned that these kids may become overweight. In fact, Marlene Schwartz, a psychologist who studies the phenomenon (现象) of overweight, notes that’s not what her data has shown in her new study.

Her group studied some 600 middle school students. Over three years, students in fifth, sixth and seventh grades were asked about their breakfast. Throughout the study bout 34 to 44 percent of all students said they regularly ate breakfast at home. Up to 17 percent or almost one in every six kids regularly ate breakfast at school. Overall, about one in every 10 kids reported having breakfast both at home and at school. And eating habits changed somewhat as the kids got older.

Surprisingly, at every age, kids who ate breakfast were less likely to be overweight. This was true even for those who ate breakfast at home and at school. Indeed, the study found no evidence of greater weight gain among students who ate double breakfasts. Rather, it found that students who skipped breakfast were those most likely to be overweight.

Skipping breakfast may set people to be over-hungry later in the day. Then someone may eat more food than their body needs. It might take the brain longer to realize “you have enough food and can stop eating now”. If true, skipping breakfast may actually lead a person to consume too many calories (卡路里) over the rest of the day.

“Earlier studies have shown this to be the case. The total calories taken in 24 hours are less when you eat a good breakfast,” says Diana Cutts, who works at the University of Minnesota in Minneapolis. “Eating healthily in the morning is really what you need to have energy. Skipping breakfast is not good for your body and brain.”
