A randomised study on the effects of fish protein supplement on glucose tolerance, lipids and body composition in overweight adults

Abstract

The popularity of high-protein diets for weight reduction is immense. However, the potential benefits from altering the source of dietary protein rather than the amount is scarcely investigated.
