Thompson SV, et al. - In this systematic review and meta-analysis, researchers examined randomized controlled trials (RCTs) of isolated soluble fiber supplementation in overweight and obese adults on outcomes related to weight management and glucose and insulin metabolism. In overweight and obese adults, isolated soluble fiber supplementation improved anthropometric and metabolic outcomes, thereby suggesting that supplementation might improve fiber intake and health in these individuals. However, because of the considerable between-study heterogeneity, they recommended practicing caution while interpreting these findings.
