About

Regular breakfast consumption may help lower body weight reduce body fatness and improve cardiovascular disease risk factors. However, the best kind of breakfast to consume to achieve these effects is unclear. We hypothesized that a high fiber breakfast would suppress appetite, lower body weight and improve cardiovascular disease risk factors compared with a no-fiber breakfast.

Full description

Participants will report to the hospital cafeteria between 0800 and 0900h following an overnight fast every weekday for 4 consecutive weeks. On arrival, participants will be provided will the allocated breakfast and will be given 15 min to consume all the foods provided. The oatmeal breakfast will consist of 80g dry oatmeal (Quaker Quick Oats) prepared with 120mL fat-free milk and 230mL water.
