Time perception is an important and adjustable aspect of human cognition. It has been suggested that diet and specific food consumption can influence an individual's perception of time. The influence of diet on time perception has been studied in relation to calorie content, control, and the emotions and nutrients associated with food. Experiments have been conducted to understand the impact of observing high- and low-calorie food pictures, with results indicating that diet-controlling individuals show a lower overestimation effect when exposed to high-calorie food images. Furthermore, the connection between time perception and eating behaviors has been explored, highlighting the role of temporal cognition, reward sensitivity, and cognitive control. The perception of food and diet also plays a role in health-related behaviors, such as weight control and the prevention of type 2 diabetes.

High-calorie foods and time perception
Time perception is an important and adjustable aspect of the human cognitive sphere. Food is believed to affect the perception of time through the emotions it triggers and the nutrients it contains, which may affect brain chemistry.
A study by Droit-Volet, S., Brunot, S. & Niedenthal, P. M. investigated the influence of observing a range of foods differing in calorific content on individuals' time perception. The study found that participants who did not control their diets were more aroused by images of food, especially high-calorie foods, and showed a less marked acceleration of their internal clock, resulting in a lower overestimation effect compared to those who controlled their diets. This suggests that the modulation in time overestimation may be linked to the arousal response generated by high-calorie food images.
Another study by Gagnon and colleagues found no effect of food pictures on perceived duration in healthy participants. However, they observed an overestimation effect from non-food to food cues in women with anorexia nervosa, which they attributed to experiential avoidance tendencies. Women with anorexia nervosa tend to rigidly avoid high-calorie foods, and when confronted with such foods, their arousal levels increase, speeding up their internal clock system and leading to an increased overestimation of time.
The influence of high-calorie food images on time perception may be related to the emotional response they evoke. The anticipation and consumption of high-calorie foods can trigger emotions such as pleasure or guilt, which can impact the perception of time. Additionally, the nutrients in high-calorie foods may also play a role in time perception. For example, a protein-rich meal can increase dopamine levels in the brain, speeding up the internal clock, while a carbohydrate-heavy meal can boost serotonin levels, potentially slowing down the internal clock.
While the specific mechanisms require further investigation, the available evidence suggests that high-calorie foods can indeed influence time perception, providing valuable insights into the complex relationship between diet and cognitive processes.

Diet control and time overestimation
Time perception is an important and adjustable aspect of the human cognitive sphere. While the nature of time is rooted in our body, our interoceptive perception of time is constantly being shaped and defined by the impulses arising from our body.
Food is proposed to be one such impulse that affects our perception of time. The specific consumption of food can influence our perception of time in two ways: through the emotions it triggers and the nutrients it contains, which may affect brain chemistry. For example, an increased intake of fruits and vegetables may cause psychological benefits, and a diet rich in these foods can improve mental well-being.
The influence of diet control on time perception has been studied through experiments using high- and low-calorie food pictures as stimuli. These experiments revealed that participants who controlled their diet reported being less aroused by the high-calorie food pictures, leading to a lower overestimation effect compared to their non-diet-controlling peers. This modulation in time overestimation is proposed to be caused by the arousal response generated by high-calorie food pictures, with more arousing pictures leading to a greater overestimation of time.
The connection between time perception and diet control has implications for our understanding of the relationship between temporal cognition and eating behaviors. The ability to accurately perceive time is influenced by diet control, which in turn can impact decision-making, impulsivity, and reward sensitivity. Thus, diet control and time overestimation are intricately linked, with potential consequences for overall health and well-being.

The influence of emotions on time perception
Time perception is an important and adjustable aspect of the human cognitive sphere. While there is no direct evidence that diet influences time perception, there is research to suggest that food can affect time perception through the emotions it triggers and the nutrients it contains.
Emotions play a significant role in shaping our perception of time. The emotional state of an individual can distort their sense of time, with negative emotions often leading to overestimations of time and positive emotions associated with shorter time duration estimations. For example, when listening to music, the tempo and key can evoke emotions of happiness or sadness, which in turn influence our perception of time. This is further supported by studies that have found that emotional sounds are judged to be longer than neutral sounds, with negative sounds judged as longer than positive ones.
The concept of an internal clock, as described by scalar expectancy theory, suggests that the brain has specific mechanisms to experience and function effectively in relation to time. Emotions are believed to influence these internal clock mechanisms, either as arousal- or attentional-based factors. Emotional stimuli can lead to overestimations in time perception by increasing the pacemaker rate. On the other hand, attentional models suggest that emotional stimuli can distract from temporal information processing, resulting in underestimations of time.
The discrete emotional approach categorizes emotions and their functions, suggesting that each emotion may have a unique effect on time perception. For example, the feeling of threat or anxiety can make time seem slower. However, the complexity of emotions and their individual functions means that further research is needed to fully understand how each emotion influences time perception.
In conclusion, emotions have a significant influence on time perception, with arousal and attention playing key roles in distorting our sense of time. While the internal clock model helps explain this relationship, further research is needed to fully understand the intricate effects of specific emotions on our perception of time.

Interoceptive time perception
Time perception is an important and adjustable aspect of the human cognitive sphere. While the way we perceive time is widely debated, it is a fundamental element of human awareness. Our consciousness, our ability to perceive the world around us, and our sense of self are shaped by our perception of time.
The nature of time is rooted in our body. Constellations of impulses arising from the flesh constantly create our interoceptive perception, and the unfolding of these perceptions defines human awareness of time. Interoceptive time perception is, therefore, a function of interoceptive processing. Interoceptive Buffer saturation (IBs) evaluates subjects’ ability to process salient stimuli from the body by measuring subjective distortions of interoceptive time perception, i.e., the estimated duration of tactile interoceptive stimulations.
Recent research suggests that the experience of time emerges from emotional and interoceptive (bodily) states as processed in the insular cortex. The insular cortex's role in the perception of time has been indicated by climbing activation in the insular cortex corresponding to stimulus length in a duration reproduction task. Interoceptive focus shapes the experience of time, with fear associated with subjective time dilation and amusement leading to a quicker passage of time.
Food is also proposed to affect the perception of time through the emotions and nutrients it triggers. Evidence suggests that following a diet rich in fruit and vegetables has psychological implications and can improve mental well-being. Studies have shown that individuals who controlled their diet reported being less aroused by high-calorie food pictures, leading to a lower overestimation effect compared to their non-diet-controlling peers.

Eating behaviours and time perception
Time perception is an important and adjustable aspect of the human cognitive sphere. The nature of time is rooted in our body and its interoceptive perception. This perception of time is influenced by the emotions and nutrients that come with the consumption of certain foods.
A study by Droit-Volet et al. (2009) explored the time-emotion paradox, which was further investigated by Droit-Volet, Fayolle, Lamotte, and Gil (2009). The latter study examined the embodiment of timing and time, emotion, and the perception of the duration of emotional events.
A 2022 study by Droit-Volet, Brunot, and Niedenthal explored the influence of observing a range of foods differing in calorific content on individuals' time perception. The results indicated that participants who did not control their diet were more aroused by images of food, especially high-calorie foods, and thus showed a less marked acceleration of their internal clock and a lower overestimation effect compared to participants who controlled their diet. This may be explained by the modulation of arousal caused by food, which affects time perception.
Another study by Wittmann and Paulus (2008) looked at decision-making, impulsivity, and time perception, while Rodin (1975) investigated the causes and consequences of time perception differences in overweight and normal-weight people. These studies suggest a link between time perception and eating behaviors, with temporal cognition influencing temporal discounting, reward sensitivity, and cognitive control.
Additionally, it has been hypothesized that increased consumption of fruits and vegetables may lead to psychological benefits and improve mental well-being. This could be due to the emotions and mindset associated with consuming these foods, which can shape our perception of time.
In summary, eating behaviors and time perception are interconnected, with the specific food consumed and the emotions it triggers playing a role in how we perceive time. Further research is needed to fully understand the complex relationship between eating behaviors and time perception.
