It is a common belief that a balanced diet and proper exercise are all that is needed to build a healthy and impressive body. In fact, the cycle of calorie intake and calorie consumption is only one aspect of maintaining a standard body weight, and other factors such as lifestyle and medication also have a significant impact on body weight. The “hidden” factors: family and friends Harvard University experts pointed out that our usual diet and the scope of activities are mainly affected by the surrounding circle, so it is inevitable that the family environment, the circle of friends to become one of the factors affecting the change of our weight. If the spouse is obese, then our chances of gaining weight will increase by 35%, while siblings are obese, the chances of gaining weight will increase by 40%, surprisingly, if a good friend is overweight, our chances of gaining weight will reach 57%. Family environment and circle of friends become one of the factors that influence the change of our weight So, the next time you notice that your waistline is getting thicker, you can put the blame on your parents or girlfriends. According to the director of ABC News Medical Channel, people’s daily behavior is subconsciously influenced by the people around them and the environment they live in, and usually, we don’t even think about making any changes. For example, your office hosts a birthday detox twice a week, and it seems to be a part of your life, so even if you’re trying to lose weight, you can’t resist the subversion of your weight loss results by this unconscious activity. The “hidden” factor 2: drugs Drugs on obesity up to 5% A recent study by Weill Cornell Medical Center in New York found that drugs on obesity up to 5% of the impact. Although this effect is only a small part, but given that millions of people in the United States are currently taking prescription drugs, so the impact of drugs on weight gain can not be underestimated. In addition, people take anti-allergy, anti-infection, heart disease, diabetes, depression and cancer-related medications on a daily basis have the greatest impact on weight gain. Although scientists can’t fully explain the reasons why drugs cause weight gain, they believe that taking drugs can make fluid retention, disrupt metabolic mechanisms, and even affect the enzymes that stimulate the appetite. “Hidden” factor 3: chemical pollutants More than 40 environmental chemicals have been identified as “fat” substances There are more than 40 environmental chemicals have been identified as “fat” substances. Certain pollutants contained in paintings, plastics, wallpaper, textiles and floor tiles can cause people to gain weight and even increase insulin levels in the body. Persistent environmental pollutants such as DDT pesticides, dioxins, and benzene have also been identified as triggers of obesity and type II diabetes. Why do chemical pollutants also contribute to weight gain? Chemicals in the air, soil, and drinking water have an effect on the bacteria that enter the digestive tract. Scientists believe that these gut bacteria interfere with weight loss by altering their synthesis, thus leading to weight gain and increased insulin in the body. “Hidden” factor 4: sleep Sleep quality does not directly affect the weight of the study found that the quality of sleep does not directly affect the weight, but a serious lack of sleep will make the weight increased significantly. Columbia University did a study on sleep habits, the results found that a night of sleep less than 4 hours of people, the odds of weight gain than 7-9 hours of sleep 73% higher; and sleep 6 hours a night, the odds of suffering from obesity than 7-9 hours of people high, 23% higher. Some studies have found that excessive fatigue, the body’s leptin will be greatly reduced, and leptin is a protein hormone secreted by fat cells, in the regulation of energy balance, eating behavior plays an important role. Similarly, sleep deprivation will also stimulate insulin, thereby inducing obesity and type II diabetes. “Hidden” factor 5: virus The body contains fat virus population weight than the virus-infected population weight gain much more The late 1980s, researchers found that chickens in the impact of a particular virus, even if they did not eat too much food, the weight will still increase. They also discovered a range of other types of viruses that caused rats, cats, dogs and pigs to gain weight. There is also some evidence of a link between human viral pathogens and obesity. Although the direct link between viral infections and weight gain is not yet clear, microscopic observation of all viruses and their antibodies in the blood vessels of infected humans has shown that people with adipose viruses in their bodies gained more weight than those who were not infected with the viruses.
