Summary

To compare the effect of eating solid vs. drinking liquid forms of gelatin, sucrose and its component mixtures and whey protein on subjective appetite and food intake in young men.

Detailed description

Three randomized cross-over design experiments were used to compare the effect of solid and liquid forms of gelatin (6 g) in experiment 1, sucrose (75 g) and a mixture of 50% glucose/ 50% fructose (G50:F50) in experiment 2, and acid and sweet whey protein (50 g) in experiment 3 on healthy normal weight males . The controls were water (experiment 1 and 3) and calorie-free sweetened water with gelatin (sweet gelatin, experiment 1) or without gelatin (sweet control, experiment 2). Subjective average appetite was measured by visual analogue scales frequently over 1 h and ad libitum food intake was measured 1 h after the treatment consumptions.
