Breakfast is food for the brain and for the rest of your body， note experts in childrens nutrition. And downing those morning calories are worth it， even for people concerned about their （A） w_________， a new study finds. Middle-school students who ate （B） b_________were more likely to have healthy weights than were those who skipped breakfast. This was true even for students who ate two breakfasts — one at home and one at （C） s_________.

"Not skipping breakfast sets you up to not overeat later in the day，" concludes Marlene Schwartz. This psychologist studies obesity（肥胖）. Breakfast is considered so （1） i_________that many schools now serve it as well as lunch. But at least one study has found that a lot of these （D）s_________who take part can end up eating two breakfasts， Schwartz notes. People became concerned that kids who ate breakfast at home and at school might become obese.

In fact， Schwartz now notes， that's not what her data have turned up. In fact， her study found no （2） e_________of greater weight gain among students who ate double breakfasts. Rather， it found that students who skipped breakfast most often were those most likely to be （3） o_________or obese.

The （E） f_________may seem puzzling. Yet Schwartz and her colleagues can think of several possible explanations.

Skipping breakfast may set people up to later in the day be "over-hungry， then they may take in more （4） c_________than their body needs"， says Schwartz. Earlier studies have shown this to be the case， says Diana Cutts， who is a pediatrician and works at the University of Minnesota in Minneapolis. "The total calories taken in over 24 hours are less when you eat a good breakfast，" notes Cutts.

But why should eating two breakfasts not lead to weight gain？ One explanation may be that school breakfasts are very （F） h_________and controlled in size. A bowl of cereal with milk and a piece of fruit is typical. So eating that along with a home breakfast may not be too many calories for active， growing middle schoolers.
