Effects of a Dietary Fibre Supplementation of a Low Calorie Diet on Appetite and Body Weight

A Randomized, Double Blind, Placebo Controlled Trial Evaluating the Effects of a High Viscosity Dietary Fibre (PGX) Supplementation of a Low Calorie Diet on Appetite and Body Weight, in Overweight and Moderately Obese Females

This 18 week, randomized, double blind, placebo controlled trial will examine the effects of thick dietary fibre (PGX) supplementation of a low calorie diet (LCD) on appetite, weight loss, body composition, and compliance in overweight and moderately obese female.

The investigators believe that 15 grams/day PGX supplementation of a low calorie diet over a 14-weeks period will elicit a better appetite score (e.g. reduced hunger) compared to the rice flour supplementation of the LCD.

Inclusion Criteria:

• BMI 25 - 35 Kg/m2

Exclusion Criteria:

• Medications and supplements that affect appetite
• Known diabetes
• Contraindications to LCD
• Any other medical, social or geographic condition, which, in the opinion of the investigator would not allow safe completion of the protocol.
