Sally stated that recent stresses in her life are affecting her sleep and seemed to have triggered her appetite for sweets and comfort foods. Which of the following statements would be best to explain why her lack of sleep has increased her appetite?
Lack of sleep increases levels of ghrelin which stimulates appetite and decreases levels of leptin which decreases appetite.

Lack of sleep increases levels of ghrelin which stimulates appetite and decreases levels of leptin which decreases appetite.

Explanation:

The two hormones are responsible for regulating the hunger affected by the sleep. The ghrelin is the hormone which stimulates the appetite, whereas the leptic is the hormone which decreases the appetite in response to the sleep. When the body experiences the sleep-deprivation or lack of sleep the level of secretion of the ghrelin increases, whereas the level of the leptin decreases, which leads to the increase in the hunger or appetite.
