Primary Outcome Measures

Name	Time	Method
Energy intake of a subsequent meal measured by providing an excess of pasta, weighing the leftovers and calculating the amount eaten by difference. The energy content of the pasta meal is known.[Three hours after eating];Postprandial blood glucose concentrations using capillary blood obtained by fingerprick. Blood glucose concentrations will be measured using a Hemocue instrument checked each morning of use with a manufacturers control.[Within the two hours following consumption at 30, 45, 60, 90 and 120 min.];Satiety assessed using paper-based visual analogue scales and food models[Within the three hours following consumption at thirty minute intervals]

Secondary Outcome Measures

Name	Time	Method
Palatability assessed with a visual analogue scale questionnaire based on that published by Flint et al (Int J Obes Relat Metab Disord 2000;24(1):38-48) with some modification including additional questions on texture and aftertaste.[Immediate response after eating];Gastrointestinal discomfort assessed with a series of questions relating to discomfort using a previously published questionnaire (Bovenschen et al. Dig Dis Sci 2000;51:1509-15) with some modification to make it specific to symptoms that may be experienced with high intakes of fibre[Within twenty four hours following consumption at 1, 2, 3, 8 and 24 hours]
