Shows the results of a 6-month study in patients with Metabolic Syndrome. A restricted diet alone showed a modest weight loss over 4 months, followed byweight re-gain. In combinationwith the restricted diet, partially hydrolyzed guar gum (3.5g bid), a less viscous readily fermented fiber, showed amarkedweight loss at 2 months followed by weight re-gain over the following 4 months. In contrast, psyllium (3.5 g twice a day), a viscous, gel-forming, non-fermented fiber supplement, inaddition to therestricteddiet, showed sustained weight loss over the 6-month study.
