Sleep Affects Weight More Than You Realize
More and more medical evidence is coming to light that suggests that sleep affects weight. The Journal of the American Medical Association and The Lancet both have published studies suggesting that sleep affects weight, i.e., the lack of sleep you get may cause hunger and possibly affect your body’s metabolism. That being said, for those who get little sleep, you most likely will eat more and retain the fat you eat, making it harder to lose or even maintain weight. Furthermore, it has been noted that the quality of sleep you get may also play role with how you feel, including whether or not you wake up hungry.
Lack of Sleep Affects Weight
As you sleep, your body’s cortisol levels decrease, while growth hormones increase. Cortisol is an anti-stress hormone that is secreted through the adrenal gland and which has an affect on the body’s appetite. Cortisol is noted as being excitatory and it has been shown in studies that the more cortisol that is secreted, the more we are hyperaroused. Additionally, studies reflect that the higher your cortisol levels are, the more likely you will suffer with mental and metabolic problems, such as insulin resistance and loss of memory. Hence, the less sleep you get, the more likely you will end up waking up hungry, while at the same time your metabolism has slowed down.
Lack of sleep also affects weight because it interferes with the body’s ability to process fat, protein, and carbohydrates. The less sleep you get, the slower your metabolism works, which then can lead to your producing more blood sugar. When the body produces excess blood sugar, the more it will store fat and become insulin resistant, which can lead to diabetes. In addition, cortisol also plays a role in the formation of collagen. Collagen is a molecule that helps the body burn fat and gain lean muscle mass that makes connective tissue.)
