What are the reasons for getting fatter? 2 obesity blind spots you don't know

Night eating is a disease

People have never regarded night eating disease as a real disease. Recently, a scientific study published in the sub-issue of Cell Reports and Cell confirmed that genes can affect eating time, and "night eating disease" does exist.

There are two genes in the human body: PER1 and PER2, which govern eating and sleeping respectively. Under normal circumstances, these two genes are synchronized. Once the PER1 gene, i.e. the period1 gene, is a gene that regulates circadian rhythm, it may lead to the so-called "night eating syndrome"-disrupted eating time, resulting in overeating and subsequent weight gain.

This research result has given many night eaters an excuse for peace of mind: night eaters are not because I have poor self-control, but because there is a genetic problem. In fact, the incidence of night eating is only 1%-2%, but the proportion of obese people is far more than that.

Most people like to eat at night, but it is their fault that they lack self-control and live irregular lives. Nightly snacks are usually junk food and high in calories. They are definitely a powerful booster of obesity. So, if you keep using night eating as an excuse, be careful that your body will be completely hopeless.

Self-test of "Night Eating Syndrome": Are you really one of them?

If you occasionally eat a late snack before going to bed, it will not be night eating. If the following phenomena occur and have been maintained for a long time, you should be careful that you may have night eating.

·I have a poor appetite during the day and don't eat much, but I eat and drink violently at night, and I am a little hungry and want to put everything I get into my mouth.

·You will feel anxious if you don't eat, and you will feel a deep sense of guilt if you eat.

·Sometimes I am already asleep and suddenly wake up looking for something to eat.

·You must eat before going to bed to fall asleep quickly. If you don't eat, it will be difficult to fall asleep, especially if you eat starchy foods or sweets.

"Night stars" play with mobile phones, the later they are, the easier they are to gain weight

Nowadays, most people like to swipe Weibo and chat on WeChat before going to bed. However, playing with your mobile phone before going to bed is also the reason that makes you fat! A new study shows that using a computer or smartphone at night can make us gain weight. There is a link between the rich blue light emitted by mobile phones or tablets at night and the increase in hunger. Under the rich blue light, hunger begins to increase 15 minutes after the beginning of the light. The results of the study were published in the scientific journal Sleep.

The study participants included 10 healthy adults who followed a regular sleep and eating plan and ate exactly consistent meals. They completed a four-day low-light irradiation experiment, during which the light intensity during the 16 hours of waking daily was less than 20 lux lighting units, and the light intensity during the 8 hours of sleeping was less than 3 lux. On the third day, they were exposed to rich blue light at an intensity of 260 lux for 3 hours 10.5 hours after waking up.

Researchers said that just three hours of rich blue light exposure at night can significantly affect hunger and glucose metabolism, indicating that exposure to ambient light to the human body will affect the body's food intake pattern and its own metabolism. The longer you are illuminated by your phone at night, the easier it will be to gain weight.

Playing with your mobile phone before going to bed will also reduce the secretion of melatonin, the hormone that manages the physiological clock. Not only will you be unable to sleep, but it will also cause obesity. In addition, when going to bed time is delayed, people will want to eat late snacks. As a result, their intestines and intestines are busy digesting while sleeping, but they cannot sleep soundly.

·1 hour of mobile phone play before going to bed =1 hour of sunbathing

Playing with your mobile phone or computer for an hour before going to bed is equivalent to spending an hour in the sun. The bright screen during the process suppresses the secretion of melatonin, which governs sleep and the biological clock. Under normal circumstances, melatonin is secreted by the pineal gland of the brain. When night falls and light stimulation weakens, the amount of melatonin secreted increases, while when the light becomes brighter, the amount of melatonin secreted decreases. Once melatonin is suppressed by bright light, the body's sleep patterns will be disrupted, and the body's metabolism will deteriorate, naturally leading to obesity.

·Bright nighttime environments may cause metabolic syndrome and obesity

Does a bright night environment just affect sleep quality? NO, which also increases the risk of metabolic syndrome and obesity. There was an experiment in which mice were still placed in a bright environment as day during the night. After one week, the weight of the mice began to increase significantly. After eight weeks, the weight gain rate of the mice exceeded 50% of that of ordinary mice.

Because they are nocturnal animals, mice generally eat at night, but in a bright "night environment", their biological clock is disturbed, and they eat during the day, increasing their food intake by 55%. The situation of humans is similar to that of mice. When in a bright night environment, the biological clock will be disrupted, eventually leading to endocrine disorders and weight gain.
