Compare Effects of a Soluble Fiber on Weight and Blood Cholesterol

CCRC: FBCx® And Body Weight Regulation in Overweight Humans

Obesity and type 2 diabetes have clearly been linked together and identified as epidemics in much of the developed world. Historically several different dietary fibers have been used as means of reducing body weight and the related development of type 2 diabetes. These studies have generated mixed, if not inconsistent, results suggesting that none of these fibers promise a solution to either of these two conditions. We are proposing to investigate the effects of including a new soluble fiber, a-cyclodextrin, FBCx® (to be called Y288 in this study), into the diet of adult overweight volunteers.

The overall aim is to investigate the effectiveness of a soluble dietary fiber, FBCx®, on weight loss and/or weight management, and blood lipid levels in overweight humans.
