Your sleep habits can have a huge impact on all aspects of your life, including your weight. If you are working on losing a few pounds, a good place to start is to track how many hours of sleep you're getting each night. Obesity rates have been rising, while hours of sleep have been dwindling, due to busy schedules and work life. While lack of sleep is most likely not the primary cause of weight gain, it can affect it in many ways.
There are four hormones that are associated with weight gain, and they are disrupted when we don't get enough sleep. The first is Ghrelin, which is released by your stomach and is responsible for letting your brain know that you're hungry. The second is Leptin, which is responsible for letting your brain know that you're full. The third is insulin, which is what your body uses to turn food into energy, and the last is cortisol, which is released when you're under stress and causes your body to store your energy as fat. When you lose sleep, your body increases the production of ghrelin so you feel hungry more, and reduces the amount of leptin, so you feel less full.
Lack of sleep also disrupts your body's ability to turn carbohydrates into energy, which causes your blood sugar to rise and that can lead to insulin resistance, as your body produces more insulin and cortisol as a result. This causes your body to store fat and sugar instead of processing it.
Losing sleep also makes it harder to control your eating habits overall, and you are more likely to make bad decisions regarding what you eat. When you're not getting enough sleep, you tend to eat later at night and crave food with a lot of fat and carbohydrates.
Studies have shown that losing weight can be good for your sleep habits. Not only can it help reduce snoring and sleep apnea, but it also reduces daytime fatigue because it greatly improves your quality of sleep. So make sure that you are getting at least 7 hours or more sleep per night, and you might experience some great benefits.
