1, Brigham Young University in the United States once published a study, saying: Watching pictures of disgusting food on Instagram often will make people's appetite worse, and even achieve the effect of losing weight, so many people use disgusting food as wallpaper.

2. Practice is the only criterion for testing truth. So professors RyanElder and JeffLarson of Brigham University recruited 232 people, divided them into two groups, and then asked them to evaluate food wallpaper pictures. Some of them actually lost weight because the food they didn't like was disgusting, and they lost weight because they couldn't eat anything.
