Researchers at Stanford University, United States, has found that healthy sleep patterns can help balance the hormones that trigger the craving for food and overeating.
Ghrelin is a hormone that stimulates hunger and occurs when we fast for several hours. Leptin is a hormone produced when we eat, and create a feeling of satiety, which closes our hunger, forcing reduced levels of ghrelin.
Numerous studies have found that people who slept only five hours or less sleep a night had higher ghrelin and lower leptin levels than those who slept eight hours at night. People who sleep less have a greater desire to eat foods rich in carbohydrates. Sleep deprivation also resulted in lectin resistance, which causes the body can not burn fat effectively, thus adding weight.
Melatonin (sleep hormone) has been shown to help restore leptin sensitivity. If you lack sleep, you do not spend enough melatonin.
