Summary

Developing functional foods that enhance satiety may be beneficial to individuals to help manage body weight.

We have previously shown that consuming a mid-morning liquid preload with increasing proportion of energy derived from whey protein and addition of polydextrose reduced voluntary energy intake at a lunchtime meal compared to a liquid preload of the same energy content but lower in protein and containing no polydextrose.

This study aims to investigate if these results can be replicated when the preload is in the form of a snack bar. We will also investigate whether the daily consumption of the snack bar has an effect on energy intake, subjective appetite and metabolic parameters compared to a control snack of the same energy but with a minimal protein content and without the addition of polydextrose.

We hypothesize that the whey protein polydextrose snack will reduce voluntary energy intake at a subsequent test meal, suppress subjective appetite ratings compared with the control snack bar.
