Today, a fairly everyday scene is to see how, at meal time, in addition to the plate on the table, there is also the illuminated mobile screen is next to it while playing a TikTok video or an Instagram reel. The habit of eating by doing scroll on social networks, reading news or answering messages has become normalized to the point of becoming invisible. However, scientific literature has been warning for years that this disconnection between the plate and the brain has measurable consequences.
The hijacking of satiety. The fact of eating while looking at the mobile screen makes us eat much worse, and this is what is known in the literature as mindless eating, which can be translated as “eating unconsciously.” Something that makes a lot of sense because when we are looking at something that interests us, we don’t even realize what we are putting in our mouths, going into automatic mode.
And this is very important, because science is quite clear that the fact of feeling full of food is not something that depends only on the gastric process, but also involves our consciousness. In this way, when we eat while paying attention to something else, we damage the episodic memory of food.
in the brain there is no adequate record of the textures, flavors or amount of food that has been put in the mouth. As a result of this “food amnesia”, the signals that indicate that the stomach has become full and that one should stop eating more become blurred. This causes us to eat more at that moment, and also, since we do not have a solid memory of having been full, we tend to eat more calories at lunch or snack.
The data. This lack of active attention during eating can be extrapolated to specific figures, and something that has been repeated a lot is that cell phone use can increase caloric intake by 30%. Although this is an extreme limit derived from the sum of several disconnection factors, since studies point to somewhat lower figures.
a study published in 2019 showed that eating with a mobile phone increases caloric intake by around 15% compared to people who are completely aware of their food. Furthermore, we do not eat more of everything but rather the nutritional profile worsens by tending towards a noticeably higher intake of fats.
In the long term, we have a studio published in 2025 by Kyoto University where regular cell phone use during meals was associated with more marked weight gain in adults. But in the case of adolescents, it is associated with a greater consumption of sugary drinks and a higher BMI attributed to multitasking with the mobile phone.
That is why it is best to always eat without any type of distraction that diverts attention from the task at hand, because otherwise there are several risks to our own health.
