Researchers discovered a unique method to control food intake by feeding the brain "breakfasts."

A new study by scientists has revealed that simply viewing images of food can influence the feeling of fullness, potentially serving as a tool for appetite control or weight loss. This approach could help many individuals effectively combat the urges of uncontrolled eating without resorting to complicated and dangerous practices, as reported by PsyBlog.

The research, led by Dr. Tjark Andersen and published in the journal Appetite, found that participants who viewed the same image of sweet food 30 times felt fuller. Additionally, after this, they chose smaller portion sizes compared to those who saw the image only three times. Dr. Andersen explained that the sensation of fullness may arise from mental engagement with food, similar to how thoughts about food can mimic the act itself.

However, the authors noted that this effect largely depends on context. For instance, novelty or variety can stimulate appetite even in the absence of physical hunger. They referenced experiments with jelly beans, where participants continued to eat beans of different colors despite feeling full, highlighting how novelty can drive consumption. Further exploration of fullness based on images showed that repetition plays a crucial role.

One thousand study participants, who were shown numerous images of M&Ms and Skittles, experienced increased cravings after viewing just two or three images. However, viewing the same image 30 times suppressed their desire. These results suggest that the method could be refined for practical use in weight management, although Dr. Andersen noted its limitations if behavior does not lead to complete abstinence from food.

Dr. Andersen proposed that in the future, this could be utilized, including the development of an app that would display repeating images of desired foods to help reduce food cravings. He envisions users selecting a type of food, such as pizza, and browsing numerous photos until the desire to eat fades.

However, the success of the method hinges on how to prevent actual food intake. To broaden the study's context, it should be noted that previous research also supports the idea that visual stimuli can alter appetite. Yet, such strategies require careful adaptation to individual behaviors and broader dietary goals of different people. Despite being a psychological tool, it is unlikely to replace the comprehensive changes in diet and lifestyle necessary for sustainable weight control.
