Hormonal
Chronic partial sleep restriction (4-5 hours/night) causes dysregulation of appetite hormones (lower leptin, higher ghrelin) and reduced insulin sensitivity, increasing the risk of obesity and type 2 diabetes.
Prioritize getting 7-9 hours of sleep per night. Chronic sleep restriction (less than 6 hours) directly alters your hunger hormones, making you hungrier and less sensitive to insulin, which significantly increases your risk of gaining weight and developing type 2 diabetes. Fixing your sleep schedule is a foundational step for metabolic health.
Laboratory studies in healthy young volunteers have shown that experimental sleep restriction is associated with a dysregulation of the neuroendocrine control of appetite consistent with increased hunger and with alterations in parameters of glucose tolerance suggestive of an increased risk of diabetes.
