Washington: Foods that are rich in protein – eggs, meat and fish for example - are more filling and hence curb overeating, Australian researchers say.
Researchers from the University of Sydney, Australia, tested three diets on 22 male and female participants.
All three diets were modified to contain 10, 15 or 25 per cent protein. Each subject spent four days on each one.
Researchers found that participants felt hungrier after the 10 per cent protein diet in the 2 hours following breakfast than they were on both higher-protein diets.
Volunteers also gave in to the urge to snack more after indulging in the diet with the least protein.
From the first day to the last, participants ate a 12 per cent greater volume of food overall on this diet.
“When protein in the diet is diluted by extra fat and carbohydrate, even by a small amount – something that has happened over recent decades in westernised countries – we keep eating in an attempt to attain our target level of protein,” New Scientist quoted Stephen Simpson, co-author of the study, as saying.
However, researchers also found that participants on the 25-per-cent-protein diet ate no less than those on the 15 per cent diet.
