How Lack of Sleep is Making You Fat
We all know that sleep deprivation carries some major dangers like mood disorders, impaired judgment, and increased blood pressure. But did you know it also causes us to gain weight?
Not only does sleep deprivation change how our cells respond to insulin, but lack of sleep makes your brain crave more food. This is due to increased appetite sensations.
When we are tired, a specific region of the brain that contributes to our appetite becomes increasingly active. Causing us to respond more easily to food smells and images.
Lets take a look further into How Lack of Sleep is Making You Fat.
Sleep Apnea and Weight Gain
According to the Journal of Clinical Endocrinology and Metabolism, just one single night of sleep loss will curb energy expenditure and increase hunger levels.
A study done at Uppsala University showcased that in twelve normal weight males, one night of sleep loss saw, “a high level of activation in an area of the brain that is involved in a desire to eat”. Whereas, lower levels were observed with regular sleep patterns.
Lack of Sleep Health Effects
In addition to this, there are several other reasons why a lack of sleep will make you fat.
• Poor Sleep Makes Eating Feel Amazing. According to Men’s health, when you skimp out on sleep, the endocannabinoid compounds in your brain are turned on. These are linked to an increased need to eat food. When food is eaten while these compounds are activated, the brain’s pleasure reward system lights up.
• Your Gut Bacteria Gets Out of Whack. A journal article in Molecular Metabolism, there are metabolic disturbances that happen after shorter periods of sleep. This includes having an effect on what your gut bacteria looks like.
• Your Burn Fewer Calories. Studies suggest that the human body actually burns fewer calories on breathing and digestion when there is a lack of sleep. Poor sleep causes your metabolism to become sluggish, which will encourage weight gain.
• You become Impulsive. When you are sleep deprived, you are more likely to make bad decisions revolving around habits. For instance, you may be more impulsive as higher-level thinking gets impaired. Thus causing habits like junk food snacking and skipping out on the gym.
That about concludes our study into How Lack of Sleep is Making You Fat. But in addition to the above, sleep deprivation leads to higher cortisol hormone levels. This is the stress hormone that signals your body to conserve energy.
Combine this with the body’s inability to properly process insulin when running on little sleep. This causes the body to hang onto items like sugar, starches, and fats, thus causing you to gain weight.
