Brief summary

The purpose of this study is to describe relationships among whey protein and its hydrolysate when consumed before a meal on pre- and post-fixed meal satiety, blood glucose and insulin in healthy young adults.

Detailed description

A randomized, cross-over design study was conducted. Whey protein preloads (5-40 g) and hydrolysate whey protein (10 g) were provided in 300 ml water. At 30 min following consumption, subjects were fed a preset pizza meal (12 kcal/kg, experiment 2). Satiety, insulin and blood glucose were measured at baseline and selected intervals pre- and post-meal.
