Cracking the Code: Decoding Hunger and Overeating with Neuro-Gastronomy

The process of deciding what, when, and how much to eat is influenced by a combination of external sensory cues and internal interoceptive signals. Visual cues, such as packaging and advertisements, can shape feeding behaviors, while feelings of hunger and fullness act as important cues in decision-making around food. The gut-brain axis, particularly the vagus nerve, plays a crucial role in communicating digestive and interoceptive signals to the brain. Poor interoceptive awareness can lead to dysfunctional eating behaviors, such as eating disorders. Cultivating a strong connection to interoceptive signals can promote intuitive eating and a more holistic approach to dietary habits, especially during the holiday season.
