Participants were randomly assigned to the: a) prebiotic fibre group (8 g/d of oligofructose-enriched inulin) or b) placebo group (3.3 g/d of maltodextrin) for 16 weeks. Visual analogue scales indicate that the prebiotic fibre group reported lower prospective food consumption and experienced greater feelings of fullness following meal consumption. Prebiotic supplementation significantly reduced energy intake at an ad libitum breakfast buffet in 11 and 12 year olds and increased fasting ghrelin concentrations. The prebiotic fibre group also showed a trend towards a greater reduction in BMI z-scores. This study demonstrates that the simple addition of prebiotic fibre to the diet of overweight and obese children improves aspects of appetite regulation.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
