Detailed explanation-1: -The hypothalamus is one of the best-studied and most important brain regions involved in the central control of feeding and energy expenditure . In particular, the arcuate nucleus (ARC) within the hypothalamus is critical for the regulation of feeding and metabolism (Myers and Olson, 2012).

Detailed explanation-2: -The hypothalamus is a key brain region in the regulation of energy balance as it controls food intake and both energy storage and expenditure through integration of humoral, neural, and nutrient-related signals and cues.

Detailed explanation-3: -The hypothalamus maintains energy homeostasis by regulating homeostatic food intake. The specific hypothalamic neurons sense nutritional and hormonal signals from the blood. It has been reported that the hypothalamus increases appetite by sensing low glucose availability, and decreases it under glucose repletion.

Detailed explanation-4: -The three parts of the hypothalamus that regulate food intake are called the ventromedial nuclei, the lateral hypothalamic area, and the arcuate nucleus. The ventromedial nuclei is the satiety center, and when stimulated, it causes the sensation of fullness.

Detailed explanation-5: -The hypothalamus helps manage your body temperature, hunger and thirst, mood, sex drive, blood pressure and sleep.
