The most common reasons for obesity are gluttony and lack of exercise. In fact, the reasons are far more than that. There are many incentives that you don’t expect at all, which will make you gain weight unknowingly.
1. Infected with a certain cold virus strain
According to a study published in the journal Pediatrics, children infected with a special cold virus – “adenovirus-36” are more likely to be obese than children who are not infected. Among the 124 children who participated in the experiment, 80% of the children infected with adenovirus-36 were obese, and their weight was 23 kg higher than that of the children not infected with the virus.
2. Use air conditioner
An article in International Obesity magazine in 2006 introduced that people who live in a comfortable constant temperature environment for a long time can not feel heat and cold, and their body temperature does not rise or fall, which can also lead to obesity. For example, the ownership rate of air conditioners in southern households with the highest proportion of obese patients in the United States has been rising in recent years, from 37% in 1978 to 70% in 1997, which can prove this point.
3. Children of working mothers
A study published in the American Journal of infectious diseases shows that children of working mothers are more likely to be obese than children of stay at home mothers. Researchers from University College London compared the weight of 8552 children in 1965 and 1889 children in 1991. The results showed that among children in 1991, children of working mothers had a higher rate of obesity. However, the researchers also said that they did not investigate the diet and exercise of these children, and maybe these factors may also affect the fatness of children.
4. Lack of sleep
A 2007 study in the United States found that lack of sleep caused a series of changes in hormones in the body. For example, glucose tolerance, which is regarded as a precursor of diabetes, may occur in the human body. At the same time, hunger and fatigue caused by insufficient sleep will reduce human activities, which will lead to obesity.
5. Tonsillectomy surgery
Researchers from St. Louis University in the United States found that children who had tonsillectomy would gain significantly more weight. In addition, it is difficult to reduce the patient’s weight and body mass index within 7 years after surgery. The body mass index will rise from 5.5% before the operation to 8.2% after the operation. Researchers believe that this is probably because the children’s appetite increased greatly after their tonsils were cut off.
6. Turn on the light to sleep at night
An experiment on mice showed that under the same diet and exercise conditions, the weight of mice sleeping with lights on increased by 50% compared with that of their counterparts sleeping in the dark within eight weeks. The researchers said that this experiment is the same as eating late at night makes people fat.
7. Children of older mothers
Research shows that children of mothers over 30 are 2.6% – 2.8% more likely to be obese than children of mothers under 25.
8. Living in a polluted environment
Environmental pollution will affect human metabolism. For example, interference substances such as bisphenol A in plastics and polybrominated biphenyls in refractory materials will cause obesity after polluting the human body. In addition, pesticides remaining in foods that affect the synthesis and metabolism of human hormones can also cause obesity.
9. Genetic genes
Among the 18 genetic markers newly identified by scientists that can lead to obesity, 13 will determine whether fat will accumulate in the waist and buttocks. When scientists find out the role of these genes, they will help patients find their own different causes of obesity according to individual conditions.
10. The mother ate too much high-fat food during pregnancy
Experiments on mice have found that a large amount of high-fat food ingested by mothers during pregnancy will make their children overweight at birth, mainly because a large amount of high-fat food ingestion will make the placenta supply excess nutrition to the fetus. In addition, children will also face greater risk of obesity than ordinary people in the subsequent growth process.
11. drugs taken
Some drugs for treating depression, diabetes, hypertension and birth control pills can make people gain weight. Between 1988 and 2002, the use of psychotropic drugs, especially antidepressants, increased by 5% in the United States. Drugs for hypertension and diabetes β- Receptor blockers can also lead to obesity.
