Emotional Eating and Abdominal Obesity: A Narrative Review of the Potential Mechanisms Underlying Their Relationship and Emerging Interventions for Their Management.

Abdominal obesity (AO), assessed through waist circumference (WC), has become a validated complementary anthropometric marker for cardiometabolic risk assessment. Growing evidence suggests that emotional eating (EE), characterized by food intake in response to emotions rather than physiological hunger cues, may be linked to AO by promoting dysregulated eating patterns rich in palatable and energy-dense foods. This behavior may contribute, directly or indirectly, to excess visceral fat accumulation. An analysis of the current evidence was conducted to examine the psychological, physiological, neuroendocrine, and gut-brain axis mechanisms underlying the association between EE and AO, as well as to explore emerging interventions for its management. A narrative review of studies published between 2015 and 2025 was carried out using PubMed and Google Scholar. Search terms related to EE, AO, physiological mechanisms, hedonic hunger, diet quality, gut microbiota, and mindful eating were employed. The findings indicate that EE is associated with emotional dysregulation, chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis, increased cortisol levels, low-grade inflammation, alterations in neurotransmitters such as dopamine, serotonin, and neuropeptide Y (NPY), as well as intestinal dysbiosis. These mechanisms favor impulsive consumption of palatable foods, visceral fat gain, and metabolic deterioration. Interventions such as mindful eating show positive effects in reducing EE; however, their anthropometric impact still requires further validation. In conclusion, EE represents an important behavioral factor in the development and maintenance of AO. Its management requires a multidimensional approach integrating emotional regulation, dietary modification, and psychobehavioral strategies.
