Abstract

Aims: This review aims to synthesize and analyze scientific evidence regarding the role of Classical Yoga (including Asana, Pranayama, and Meditation) in regulating appetite-controlling hormons (Ghrelin, Leptin, Adiponectin) and their subsequent impact on Emotional Eating (EE) behaviors.

Methods: A narrative review approach was employed, collecting data from reputable academic databases such as PubMed, ScienceDirect, and Google Scholar, over a 10-year period (2014–2024).

Inclusion criteria focused on Classical Yoga intervention studies and systematic reviews related to the endocrine mechanisms of Yoga on the hypothalamic-pituitary-adrenal (HPA) axis and metabolic hormons in adults or individuals exhibiting emotional eating.

Results: Evidence suggests that Classical Yoga helps reduce Cortisol levels by modulating the HPA axis and the autonomic nervous system, thereby attenuating false hunger signals (hedonic hunger) rather than physiological hunger. Specifically, regular Yoga practice is associated with higher levels of Leptin and Adiponectin (satiety and anti-inflammatory hormons) and decreased levels of Ghrelin (the hunger hormon), which improves the self-regulation of eating behaviors and reduces stress-induced cravings.

Conclusion: Classical Yoga extends beyond mere physical exercise, serving as a potential intervention strategy for modulating endocrine dysregulation associated with eating behaviors. Integrating Yoga into daily routines can assist individuals in sustainably managing emotional eating through hormon-balancing mechanisms and enhanced interoceptive awareness.
