Brief Summary
The objectives of the research are to assess the effects of increased protein and fiber intake at breakfast on neural activation in brain regions associated with appetitive drive and reward-driven eating, measures of subjective appetite, and ingestive behavior in overweight adults. Additional outcomes of interest include the effects of the breakfast intervention on blood sugar and cholesterol profiles.

Outcome Measures
Primary Outcomes (1)
Brain activation measured with functional magnetic resonance imaging and its association with measures subjective of appetite, self-selected daily energy intake, and energy intake at an ad libitum lunch.
Aim 1: Assess the effects of a higher than normal protein and fiber intake at breakfast on neural activation of brain regions associated with appetitive drive and reward-driven eating, measures subjective of appetite, self-selected daily energy intake, and energy intake at an ad libitum lunch.
16 weeks
Secondary Outcomes (2)

Study Arms (4)
Average Protein and Fiber at Breakfast
EXPERIMENTALDietary control of protein and fiber intake at breakfast. Participants will eat a 400 kcal breakfast with an average amount of protein and fiber for this age group for 2 weeks.
Average Protein and High Fiber at Breakfast
EXPERIMENTALDietary control of protein and fiber intake at breakfast. Participants will eat a 400 kcal breakfast with an average amount of protein and higher than average amount of fiber for this age group for 2 weeks.
High Protein and Average Fiber at Breakfast
EXPERIMENTALDietary control of protein and fiber intake at breakfast. Participants will eat a 400 kcal breakfast with an average amount of fiber and higher than average amount of protein for this age group for 2 weeks.
Higher Protein and Fiber at Breakfast
EXPERIMENTALDietary control of protein and fiber intake at breakfast. Participants will eat a 400 kcal breakfast with a higher than average amount of protein and fiber for this age group for 2 weeks.
Interventions
Participants will be provided breakfast meals for 4, 2 week long interventions. The intervention arms are 1) average protein and fiber, 2) average protein and high fiber, 3) high protein and average fiber, and 4) high protein and fiber.
