Evaluation of the satiating properties of a fish protein hydrolysate among overweight women

Abstract

Purpose – This paper aims to investigate the satiety properties of a fish protein hydrolysate (blue whiting muscle hydrolysate, BWMH). Protein consumption is associated with higher satiety, protein being considered as the more satiating macronutrient. This property is extensively investigated in regard to weight management. Design/methodology/approach – Fifteen overweight women were included in a crossover design study. Subjects consumed 1 g of BWMH or placebo twice daily and sensations associated with satiety were recorded every day. Findings – Significant differences, in favour of BWMH, were highlighted on the desire to eat something sweet at T90 min (p < 0.05) and on plasma glucose at T270 min (p < 0.05). Research limitations/implications – This study demonstrates effect of BWMH on appetite. Indeed promising data were reported in favour of the test product, in particular on the desire to eat something sweet and on glucose levels. Some additional investigations will be necessary to support these data and those observed in in vitro and in vivo models. Originality/value – After promising pre-clinical data, this study is a first investigation of health benefits of BWMH supplementation in humans.
