Adolescent obesity, negatively affecting the lives of over 18 million (34%) US adolescents, continues to be a major public health concern due to the increased risk of developing chronic diseases, including type 2 diabetes. Thus, there is a great need to develop effective, dietary strategies that target health outcomes, including weight management and glycemic control in young people. One particular strategy that is gaining scientific support includes the daily consumption of a protein-rich breakfast. This study will identify the potential role of protein at breakfast as a key component of a healthy diet for improvements in appetite control, satiety, and weight management to reverse the obesity epidemic and prevent and/or delay serious health complications in young people.
