If you're trying to lose weight, the amount of sleep you get may be just as important as your diet and exercise.
Here’s why sleep is so important:
· poor sleep is associated with weight gain and a higher likelihood of obesity in both adults and children
· people who are sleep-deprived report having an increased appetite. This is likely caused by the impact of sleep on two important hunger hormones, ghrelin and leptin. When you do not get adequate sleep, the body makes more ghrelin (hunger hormone) and less leptin (satiety hormone), leaving you hungry and increasing your appetite. In addition, the hormone cortisol is higher when you do not get adequate sleep. Cortisol is a stress hormone that may also increase appetite.
· poor sleep can decrease your self-control and decision-making abilities and can increase the brain's reaction to food. Poor sleep has also been linked to increased intake of foods high in calories, fats and carbs.
· sleep deprivation may lower your metabolic rate.
· poor sleep can cause cells to become insulin resistant, which makes you hungrier and tells the body to store more calories as fat.
