lose weight

 No. But if you want to lose weight or keep fit, you need 7–9 hours of regular quality sleep (individual needs may vary). Chronic lack of sleep can be one of the reasons for overweight. We tell you what happens to the body when you sleep poorly.

Levels of hormones affecting appetite change

Lack of sleep affects hormones that are responsible for the feeling of hunger and satiety: ghrelin and leptin.

Ghrelin is an appetite stimulant that signals the brain about hunger. Ghrelin levels increase when the stomach is empty, and decreases after eating.

But the level of leptins increases after eating – it suppresses appetite and informs the brain about satiety.

In addition, with a lack of sleep, the level of the stress hormone cortisol increases – this can also increase appetite.

Carbohydrate metabolism is disturbed

Bad sleep can lead to insulin resistance when muscle, fat, and liver cells do not respond to insulin in the right way and cannot easily extract glucose from the blood. As a result, the pancreas produces more insulin to help glucose enter the cells.

Excess insulin causes a feeling of hunger, and the body begins to store more calories in the form of fat. Uncontrolled insulin resistance over time can lead to weight gain and type 2 diabetes.

Craving for junk food

Scientists suggest that in a sleepy person, reward centers in the brain are more susceptible to food – and the craving for high-calorie, fatty, and sugary foods increases.

In addition, lack of sleep affects the frontal lobe of the brain, which is responsible for decision-making and self-control – because of this it is more difficult to make a choice in favor of healthy food.

Increased calorie intake

People who sleep little tend to consume more calories. This can occur due to tonight snacks by snacks, a long time without sleep, overeating buy Ativan online 

When analyzing case studies, it was found that on average after a night of insufficient sleep, people consume 385 calories more.

Metabolism worsens

Scientists have suggested that poor sleep can reduce basic metabolism.

Thus, when you sleep little or poorly, the body at rest spends less energy on functioning. If you want to lose weight, it will be harder to do.

Physical indicators are reduced

Lack of sleep causes fatigue, reduces attention, ability to concentrate, motivation for training. Adequate sleep, on the other hand, helps increase productivity.

In a 2011 American study, basketball players slept 10 hours every night for a week instead of the usual 6–9 hours. As a result, their speed increased, reaction time and accuracy improved, and fatigue decreased.

In addition, with a lack of sleep, the level of the stress hormone cortisol increases – this can also increase appetite.
