简要总结
The purpose of this study is to determine whether ingestion of a bar containing either added soy protein or soy fiber or both, increases subjective and objective measures of satiety compared to a control bar.
详细描述
The study will use a randomized, double blind crossover design in which subjects act as their own control. Satiation will be assessed using a Motivation to Eat Questionnaire. Height and weight will be measured at the screening visit and weight alone at each subsequent visit. Prior to consumption of the test meal (breakfast) and at 15, 30, 60, 90, 120 and 150 min thereafter, subjects will complete a VAS Motivation to Eat Questionnaire. After subjects complete the first VAS motivation questionnaire, they will be given the test meal and instructed to eat this over a 15 minute period and fill out a palatability questionnaire. Two hours after the start of the test meal they will be taken to a private feeding room, where an ad libitum pizza lunch will be served with mineral water. Participants will be instructed to eat and drink as much as they desire until they are comfortably full. Subjects will be asked to fill out a final VAS Motivation to eat questionnaire 30 min after the start of the pizza meal.
