The study investigates the health effects of cod protein, both from fillet and residual materials, on overweight or obese adults. Given the rising prevalence of obesity and related metabolic disorders, this research could position cod protein as a functional food ingredient with potential applications in dietary supplements and food products targeting cardiovascular health and glucose regulation. The findings may open avenues for partnerships with food manufacturers and health supplement companies, particularly in markets focused on obesity management and chronic disease prevention. The competitive landscape includes other protein sources and dietary interventions, necessitating a clear differentiation based on efficacy and health benefits derived from cod protein.
