losing sleep = gaining weight??
Are you getting at least 8 hours of sleep a night? If you aren't then don't be surprise if you find yourself gaining a little weight. Don't worry; it won't happen overnight. Before it does you will need to grasp some causes of sleep loss in addition to what happen to you after you start losing sleep.
why you may be losing sleep
There are three main causes of sleep deprivation: choosing to sleep too little, lack of time to sleep, and medical conditions.
There are all kinds of reasons that you lose sleep such as being so busy that you don't have 8 hours a day to spare. You got to go. Another is that exercising immediate before going to bed is causing you to lose 1 hour of sleep a day that is like losing 1 day of sleep per week. For what ever reason you have for losing sleep, it doesn't matter; no matter what reason it may be, changes are you will be gaining weight very soon if you are not careful.
not sleeping makes you hungry
Past experimental studies show that sleep restriction increases hunger and appetite
Losing sleep makes you hungrier, which makes you prone to gaining weight. People who get less sleep at night are said to have high levels of "glutton molecules" in their blood. These molecules that have been found to be high when you lack sleep, makes eating food more satisfactory.
leptin decreases when you lack sleep, your body reacts to this by releasing ghrelin causing you to start to feel hungry
As you lose sleep, the hormone ghrelin produced by your stomach increases making you feel more hungry, which makes sense if you think about where the message is coming from. You eat and leptin levels increase, slowing down the production of ghrelin from your stomach. In other words, sleeping helps keep the balance between leptin andd ghrelin in your body stable, making it easier to pin down your hunger.
how do the sleep requirements of humans size up with animals
unlike some animals, humans are active during daylight hours.
You and I need 8 hours a sleep each day to function properly. On the other hand animals require varied amount of sleep. For example, the brown bat require close to 20 hours a sleep a day; whereas giraffes can get away with only 2 hours. See Sleep―Information about Sleep for more details.
sleep loss and weight gain
findings suggested that one unfortunate result of sleep loss is this “double hit” in brain activity
When tired, there is something different about you. On top of feeling jumpy, easily startled, you are more likely to give into the impulse to eat.
a sleepy brain appears to not only respond more strongly to junk food, but also has less ability to rein that impulse in.
Imagine having the biggest case of munchies and not being able to stop yourself from overeating. That's what you are like what you are losing sleep. Not something that is going to help you balance your diet.
