Fish protein hydrolysate for the use thereof in inhibiting weight gain and/or weight loss

Non-therapeutic use of a fish protein hydrolysate obtained by enzymatic hydrolysis of at least protein source chosen from the group composed of the following fish:

• Micromesistius poutassou, Clupea harengus, Scomber scombrus, Sardina pilchardus, Trisopterus esmarki, Trachurus spp., Gadus morhua, Pollachius virens, Melanogrammus aeglefinus, Coryphaenoides rupestris, fish belonging to the order Siluriformes, said enzymatic hydrolysis being performed by an endopeptidase enzyme derived from Bacillus subtilis, for causing weight loss or the limitation or inhibition of weight gain without inducing any limitation to the food intake or any phenomenon of satiety.

Method of therapeutic treatment and/or prevention of excessive weight and/or illnesses related to excessive weight without inducing any limitation to the food intake or any phenomenon of satiety, characterised in that it consists of orally administering a fish protein hydrolysate obtained by enzymatic hydrolysis of at least one protein source chosen from the group composed of the fish Micromesistius poutassou, Clupea harengus, Scomber scombrus, Sardina pilchardus, Trisopterus esmarki, Trachurus spp., Gadus morhua, Pollachius virens, Melanogrammus aeglefinus, Coryphaenoides rupestris, fish belonging to the order Siluriformes, the said enzymatic hydrolysis being carried out by an endopeptidase enzyme derived from Bacillus subtilis.
