When you do not sleep well, it tends to make you eat more and gain weight. Study shown that depriving people of sleep for one night created pronounced changes in the way their brains responded to high-calorie junk foods. If you do not have a proper sleep, fattening foods like potato chips and sweets stimulated stronger responses in a part of your brain that make you eat more. But at the same time, people will also experience a sharp reduction in activity in the frontal cortex, a higher-level part of the brain where results are weighed and rational decisions are made.

Lack of sleep makes you fat; it causes multiple harmful activities in brain. A sleepy brain appears to not only respond more strongly to food that are bad for you, but also you will has less control that impulse. When you do not sleep well, you eat more food simply to make up for all the calories they expend as they burn the midnight oil. But the new finding even showed that the changes in brain activity were factor even when the subjects were fed extra food and not experiencing any increased sensations in hunger.

The negative correlation of lack of sleep and weight gain is easy to see. Many studies show that both grown ups and children are more likely to be fat and obese the less they sleep at night. Also stress hormone cortisol climbs and markers of inflammation rise. Hormones that stimulate appetite increase, while hormones that blunt it drop. People become less sensitive to insulin, increase the potential of Type 2 diabetes.

The accumulating effects of lack of sleep will catch up to us, your body will eventually crash. In order to achieve good health, sleep well is a huge part of it. We should have 8 hours of quality sleep every night.

For people who are sleep-deprived, they strongly preferred the food choices that were highest in calories, like desserts, chocolate and potato chips. The sleepier they felt, the more they wanted the calorie-rich foods. In fact, the foods they requested when they were lack of sleep added up to about 600 calories more than the foods that they wanted when they were well rested. Brain scans also showed that on the morning after one’s sleepless night, the heavily caloric foods produced intense activity in an almond-shaped structure called the amygdala, which helps regulate basic emotions as well as our desires for things like food and experiences. That was accompanied by sharply reduced responses in cortical areas of the frontal lobe that regulate decision-making, providing top down control of the amygdala and other primitive brain structures.

Without enough rest, adenosine builds up and may lead to poor communication between networks in the brain. Getting a good sleep may be a good reset of your brain. Brain networks may even start to break down and become dysfunctional. You brain needs a good night of sleep, best thing for people to do to reset their brain and body health.

Lack of Sleep Makes You Fat

If you’re feeling sleepy at work, you may want to reach for a cup of coffee (or several cups) and a cookie for a quick shot of energy. Later you may skip the gym and pick up takeout on your way home to your family — no time to cook. When you finally find yourself back in your bed, you are too wound up to sleep. It’s a vicious cycle, and eventually this sleep deprivation can sabotage your waistline and your health. You may be able to fight off sleepiness. But unwanted pounds as poor food choices coupled with lack of exercise set the stage for obesity and further sleep loss. The accumulating effects of lack of sleep will catch up to us, your body will eventually crash. In order to achieve good health, sleep well is a huge part of it. We should have 8 hours of quality sleep every night.

Lack of Sleep Affects Our Ability To Lose Weight

The two keys hormones ghrelin and leptin, will affect your ability to lose weight. Ghrelin tells you when to eat, and when you are sleep-deprived, you have more ghrelin. And Leptin tells you to stop eating, and when you are sleep deprived, you have less leptin. More ghrelin plus less leptin means getting fat. Women who slept less than six hours a night or more than nine hours were more likely to gain 11 pounds compared with women who slept eight hours a night. You will see similar results for children too,

So it is very important for you to get a good night’s sleep.
