Brief summary

The primary aim of this study is to investigate the effect that a viscous fibre supplement, PGX, has on frequency of eating occasions in overweight adults, over a 12-week period. In addition to this, body weight, waist circumference, blood pressure and fasting venous blood samples will be measured both at baseline and post-intervention. The blood samples will be used to measure glucose, insulin, changes in insulin sensitivity, triglycerides, cholestrol (total, HDL and LDL) and apoB48. Eating occasions will be recorded using a mobile device food record and automatically uploaded to a server for analysis. It is hypothesised that the fibre supplement will reduce the frequency of eating occasions, leading to a subsequent reduction in body weight. OBJECTIVES 1. To investigate the effect of a viscous fibre supplement on frequency of eating occasions in overweight adults, over a 12-week period. 2. To measure body weight, waist circumference, blood pressure and fasting venous blood samples differences between baseline and at the end of the 12-week intervention. Aim 1. To investigate the effect of a viscous fibre supplement has on frequency of eating occasions in overweight adults Hypothesis Overweight adults receiving the viscous soluble fibre (PGX) will significantly reduce their intake of energy-dense nutrient poor foods and number of eating occasions compared with controls

Interventions

1. a) Viscous fibre supplement, PGX, 5g two or 3 times daily administered over a 12-week period. b) mode is granules mixed with food and taken with water 2.unused sachets will be returned and a daily mobile phone food record will be taken and images are sent to the Curtin University server Viscous fibre supplement.
