It also identifies role of hormonal regulators such as leptin, ghrelin, insulin, and cortisol in appetite and energy metabolism. Neurophysiological centers, particularly hypothalamus, significantly influence hunger and satiety. Adipose tissue acts as an endocrine organ, releasing pro-inflammatory cytokines. Additionally, gut microbiota imbalances have been linked to altered nutrient absorption and metabolic dysfunction.

Addressing its physiological foundations alongside lifestyle interventions may enhance effectiveness of treatment strategies and public health policies.</span></em></p> |
