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

September 30, 2015 updated by: Canadian Center for Functional Medicine

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.
