According to a new study, simply looking at pictures of food online can make you feel fuller. Of course there's more to it than just looking at food pics randomly. The study said that those who looked at the same image of food over 30 times felt more satisfied/ full and in turn ate fewer calories.
The study author, Tjark Andersen, a food science Ph.D. student at Aarhus University in Denmark, explained:
“In our experiments, we showed participants the same food picture 30 times, which made them feel more satiated than before they viewed the picture. Those shown the picture multiple times also chose a smaller portion size than those who only viewed it three times.”
