The purpose of this study is to assess whether the daily addition of a protein-rich breakfast leads to beneficial changes in appetite control, food intake regulation,and cognitive function in overweight & obese 'breakfast skipping' young women.
Breakfast skipping, which is a common, yet unhealthy dietary habit among young women, has been strongly associated with over-eating (especially in the evening), weight gain, and obesity. Breakfast skipping has also been shown to reduce cognitive function in this population. However, it is unclear as to whether the addition of breakfast, with specific emphasis on increased dietary protein, leads to improvements in these outcomes. This study will provide mechanistic evidence supporting the addition of a protein-rich breakfast to improve and/or re-establish appetite control, energy intake regulation, and cognitive function in overweight/obese 'breakfast skipping' young women. 25 overweight and obese 'breakfast skipping' adolescent girls will participate in the following randomized within-subject crossover-design breakfast study. The participants will randomly complete the follow breakfast patterns at home for 6 days: 1) Breakfast Skipping; 2) Consumption of Normal Protein breakfast meals(i.e., 350 kcal; 15% of the meal as protein, 65% CHO, & 20% fat); and 3) Consumption of Protein-Rich breakfast meals (i.e., 350 kcal; 40% of the meal as protein, 40% CHO, & 20% fat). On the 7th day of each pattern, the participants will report to the MU-Brain Imaging Center in the morning to complete the respective 10-h testing day. The participants will begin the testing day by either skipping breakfast or consuming their respective breakfast meal. Blood samples and assessments of perceived appetite, pleasure/reward, and cognitive function will be collected/completed at specific times throughout the day. A standardized lunch will also be provided. Prior to dinner, a brain scan will be completed using functional magnetic resonance imaging (fMRI) to identify brain activation patterns in response to food pictures. Following the fMRI, the participants will be provided with an ad libitum dinner buffet to consume of the facility. They will also be given evening snacks to consume ad libitum, at home throughout the remainder of the day. There is a 7-day washout period between each breakfast pattern. Primary outcomes include morning, mid-day, afternoon, and evening appetite, satiety, pleasure/reward, hormonal responses (plasma glucose, insulin, ghrelin, and PYY concentrations), brain activation patterns, evening energy intake, and daily energy intake.

The lack of sufficient energy or protein to meet the body's metabolic demands, as a result of either an inadequate dietary intake of protein, intake of poor quality dietary protein, increased demands due to disease, or increased nutrient losses.
A ubiquitously expressed regulatory protein that contains a retinoblastoma protein binding domain and an AT-rich interactive domain. The protein may play a role in recruiting HISTONE DEACETYLASES to the site of RETINOBLASTOMA PROTEIN-containing transcriptional repressor complexes.
An AT-hook motif-containing protein (AT-HOOK MOTIFS) that binds to the minor grove of AT-rich regions of DNA. It is a truncated form of HMGA1a protein that is produced by alternative-splicing of the HMGA1 gene. It may function as an architectural chromatin binding protein that is involved in transcriptional regulation.
An 11-kDa AT-hook motif-containing (AT-HOOK MOTIFS) protein that binds to the minor grove of AT-rich regions of DNA. It is the full-length product of the alternatively-spliced HMGA1 gene and may function as an architectural chromatin binding protein that is involved in transcriptional regulation.
A heterotetrameric transcription factor composed of two distinct proteins. Its name refers to the fact it binds to DNA sequences rich in GUANINE and ADENINE. GA-binding protein integrates a variety of SIGNAL TRANSDUCTION PATHWAYS and regulates expression of GENES involved in CELL CYCLE control, PROTEIN BIOSYNTHESIS, and cellular METABOLISM.
