Synopsis: Proprietary fiber blends are commonly used in dietary supplements aimed at supporting appetite control, and there is moderate scientific evidence to support this application. Dietary fibers—including soluble and insoluble types—are known to promote satiety by slowing gastric emptying, increasing feelings of fullness, and modulating appetite-regulating hormones such as ghrelin and peptide YY. Clinical studies have shown that fiber supplementation can reduce subjective hunger and overall caloric intake. For instance, a meta-analysis published in Obesity Reviews (2016) found that increased fiber intake was associated with reduced appetite and modest weight loss. Common fibers in proprietary blends may include psyllium husk, glucomannan, inulin, and others. Each of these has been individually studied and shown to have appetite-suppressing effects through various mechanisms, such as water absorption and gel formation in the stomach. However, the strength of evidence varies by fiber type, dosage, and individual response. Blends may provide synergistic effects, but proprietary formulations can lack transparency, making it difficult to attribute efficacy to specific components. Overall, while more high-quality, long-term studies are needed, the current scientific literature moderately supports the use of fiber blends for managing excessive appetite.
