“…There are no known published trials investigating these issues in which soluble fiber has been provided as an intrinsic component of food during a hypocaloric diet. As summarized elsewhere [6], previous studies on soluble fiber and weight loss [3,4,[7][8][9][10][11][12][13][14][15][16] have yielded inconsistent results, possibly due to the effect of uncontrolled differences between studies such as study duration, protocol, compliance with study diets, amount and type of fiber and how incorporated into the diet, and dietary macronutrient content. There are insufficient numbers of trials to establish if soluble fiber as a food component benefits body weight, and the trials of soluble supplements do not support a clear dose-response relationship.…”
