Chronic overnutrition triggers intracellular stress (oxidative, ER, and autophagy defects) in the hypothalamus, which activates proinflammatory pathways (IKKβ/NF-κB and JNK), leading to central neuroendocrine dysregulation and metabolic syndrome.
This research suggests that chronic overeating causes inflammation in the brain's hypothalamus, which disrupts the body's ability to regulate weight and blood sugar. Simply focusing on peripheral fat loss might not address the root cause if the brain's regulatory system remains inflamed. Strategies that reduce central inflammation or improve hypothalamic health may be critical for treating metabolic syndrome.
This type of nutrition-related molecular inflammation in the central nervous system, particularly in the hypothalamus, can form a common pathogenic basis for the induction of various metabolic syndrome components such as obesity, insulin resistance, and hypertension.
