Breakfast is food for the brain. And it’s good even for people worrying about their weight. Middle school students who eat breakfast are more likely to have healthy weight than those who don’t eat breakfast. This is true even for students who eat two breakfasts — one at home and one at school. “Not skipping(跳过) breakfast helps you not overeat later in the day,” says Marlene Schwartz.

One study has found many kids end up eating two breakfasts. People become worried that kids who eat breakfast both at home and at school might become overweight. In fact, Schwartz now says that’s not what her data(数据) have turned up.

Her group studied 600 middle school students. Over three years, students from 12 different schools were asked about their breakfast. About 34 to 44 percent of all students said they usually ate breakfast at home. Almost one in every six kids usually ate breakfast at school. About one in every 10 kids ate breakfast both at home and at school. Eating habits changed as the kids got older. For example, fifth graders were more likely to eat breakfast. But 22 percent of the seventh graders often didn’t eat breakfast. 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.

The study found no evidence(证据) of greater weight gain among students who ate double breakfasts.

Why should eating two breakfasts not lead to weight gain? The researchers don’t know yet. But one explanation may be that school breakfast is very healthy and controlled in size. So eating that along with the home breakfast may not be bad for most active and growing middle school students.
