Brief Summary:
The objective of this study was to describe relationships among whey protein when consumed before a meal on food intake and pre- and post-meal satiety, blood glucose in healthy young adults.

Condition or disease Intervention/treatment Phase
Diabetes Prevention Obesity Prevention Other: dietary intervention Other: water control Not Applicable

Detailed Description:
A randomized, cross-over design study was conducted. Whey protein preloads (10-40 g) were provided in 300 ml water. At 30 min following consumption, subjects were fed an ad libitum pizza meal. Satiety, and blood glucose were measured at baseline and selected intervals pre- (0, 15 and 30 min) and post-meal (50, 65, 80 and 95 min).
