Eat a Good Breakfast to Maintain Healthy Body Weight (BMI)
A research study recently published in the journal Pediatrics indicates that teen agers that eat a regular breakfast are more likely to make healthy diet choices, engage in regular exercise and maintain a healthy body weight. The results came after a five year scientific study among as many as 5000 youths. The study suggests that among the participants, daily breakfast eaters come from a higher socioeconomic background, are more likely to engage in high levels of physical activity and choose more nutritious foods.
The principle question on the survey was: “”During the past week, how many days did you eat breakfast?” Responses included never, 1 to 2 days, 3 to 4 days, 5 to 6 days, and every day”. The Body Mass Index (BMI) change over the course of the study was significantly higher among the group the never ate breakfast.

There are a lot more interesting details in the actual report that you can access in the links below. It would seem there really is evidence to suggest that Breakfast is the most important meal of the day. Bon Appétit!
