Weight gain noticeable through sleep deprivation
It has been known for years that too little sleep is bad for human health. Researchers have now found that poor sleep actually increases the likelihood of us gaining weight. When people sleep less than seven hours, the effects are comparable to consuming an additional four slices of toast a day, the British scientists report.

The researchers at the recognized King’s College London found that poor sleep can lead to weight gain. The doctors published the results of their study in the journal "European Journal of Clinical Nutrition".

Do you have sleep problems?
Do you often sleep poorly at night or just too short? Then you are exposed to an increased risk of gaining weight. Because poor sleep causes you to lose weight, the medical professionals warn.

Disruption of the body's clock affects the hormone ghrelin
Systematic review by King’s College London found that less than seven hours of sleep a night resulted in us consuming an average of 385 more calories a day compared to people who sleep longer. The disruption of the body's clock seems to influence the hormone ghrelin, which controls hunger and the hormone leptin, the authors explain.

Study analyzes data from eleven older studies
For their study, the researchers analyzed the data from a total of eleven previous studies with a total of 172 participants. This research compared the effects of “restricted” and “unrestricted” sleep. To do this, they measured the energy consumption of the participants within the next 24 hours, the experts say. The amount of sleep restriction varied across studies.

Test group slept between 3.5 and 5.5 hours a night
Subjects with sleep restrictions slept 3.5 to 5.5 hours a night. The control group, however, spent between seven and twelve hours in bed. Going to bed early and getting enough sleep is good for our health, explains Dr. Gerda Pot from King’s College London.

People with little sleep show higher fat and lower protein intakes
When people stayed awake longer, the study did not tend to use more energy. This indicates that the additional waking hours were spent lying on the sofa or even eating snacks, the scientists explain. In total, such subjects had an additional energy gain of 385 calories per day. This is roughly the sum of the calories from four slices of toasted bread. The researchers also found that people with insufficient sleep had proportionately higher fat and lower protein intakes.

Deprivation of sleep affects imbalance between calorie intake and calorie consumption
The main cause of obesity is an imbalance between calorie intake and calorie consumption. Deprivation of sleep seems to affect this imbalance, explains author Dr. Gerda Pot from King’s College London. If long-term sleep deprivation continues to lead to increased calorie intake of this magnitude, this process can certainly contribute to weight gain.

Further research is urgently needed
Reduced sleep is one of the most common and potentially modifiable health risks in today's society where chronic sleep loss is becoming more common, says Dr. Pot. More research is now needed to investigate the importance of long-term sleep deprivation as a risk factor for obesity.

Effects of sleep deprivation
Lack of sleep affects human performance, attention and long-term memory, and lack of sleep also promotes drug and alcohol consumption, the experts warn. In addition, lack of sleep causes fatigue, anxiety, frustration, anger, impulsive behavior, weight gain, willingness to take risks, high blood pressure, reduced immunity, stress and an abundance of psychological problems.
