The change of lifestyle and circadian rhytmicity brings due to arteficial illumination and electronic media hormone-conditioned changes
leading to disorders of food intake and energy expenditure. Changes take place in all cascades of neurohumoral management since
childhood and have a regressive influence on lifestyle. NPY/AgRP neurons stimulate food intake, in contrast orexin A and B, melatonin
and CART/POMC neurons suppress good appetite. Thyroid-stimulating hormone (TSH) supports energy expenditure, Growth hormone
(GH) reduces glucose utilization at the level of the hypothalamus. Leptin and ghrelin act on the hypothalamic nuclei feedback, cortisol
also plays an important regulatory role. Obstructive sleep apnea (OSA) is a separate risk factor. Treatment by CPAP influences the level
of ghrelin and orexin, however, usually does not change BMI. Common diseases disorders of metabolism and sleep are Night eating
syndrome (NES), Sleep related eating disorder (SRED) and Gastroesophageal reflux.
