Summary

This study will have the primary aim to investigate within-day changes in appetite after consumption of high-protein (HP, 30% of calories) and normal, or low, protein (LP, 15% of calories) whey protein meal, in solid and liquid form, on appetite and ad libitum food intake. Secondary objective will be to assess the statistical relationship between plasma concentrations of gut hormones and visual analogue scales (subjective hunger and fullness) and transit time.

In order to investigate the interaction of food structure and protein content on appetite, this requires, in practice, either a differing amount (g) or calorie (kJ) load as a function of energy density (defined as kJ/100g). Delivering the test meal as a solid and liquid form gives an easy solution to achieve this manipulation without compromising the nutritional profile. Following on from this decision, it is easier to produce different preloads using whey protein (rather than meat protein), since it is easily incorporated into test meals.
