Have you ever noticed how when you get little sleep you crave foods that give you a quick burst of energy There's a good reason for it.

Lack of sleep has been directly linked to things like stress, overeating, and weight gain.. The fact is that two hormones in the human body that regulate normal feelings of hunger and satiety are associated with the amount and quality of sleep..

The first of these, ghrelin, stimulates appetite, while the second, leptin, sends signals to the brain when we are full..

However, when our bodies don't get enough sleep, the levels of the hormone ghrelin jump up, thereby stimulating appetite - so we eat much more food than usual.. Meanwhile, due to lack of sleep, the level of the hormone leptin decreases.. This means that we will not feel satisfied even after a hearty meal..

Thus, the greater the lack of sleep, the more food the body requires.. In addition, feeling tired can also increase stress levels, leading to an even higher risk of emotional eating.. In order to control your appetite, a person needs about eight hours of good sleep each night..
