The following are the situations that easily lead to weight gain in daily life. In order to further consolidate your weight loss achievements, you should avoid them during weight loss. 1, cold: viruses can increase fat. Researchers have found that a virus that causes colds and throat inflammation can lead to obesity, and this virus can rapidly increase the number of fat cells in the body. 2, lack of sleep: obesity is the most likely. People who sleep less than 4 hours a day are 73% more likely to be obese than those who sleep normally. Studies have shown that people who lack sleep have higher levels of factors that promote appetite. 3. Relatives and friends: Obesity can also be "contagious". If a person's friend is fat, his probability of obesity will increase by 57%. The reason is that if your friends or relatives are obese, it will change a person's acceptance standard of reasonable weight and affect his diet structure and lifestyle. 4. air conditioning: the mechanism of regulating heat is blocked. Air conditioning keeps us in a constant temperature environment, so we don't have to adjust the heat in our bodies. But if the temperature is very low, our bodies will automatically consume it. 5. Gene: Mutation leads to high weight. British scientists have discovered a gene variant that regulates the amount of body fat. People with this genetic variation weigh 65438±0.2kg on average compared with those without this genetic variation. 6, hormones: control hunger. Scientists pointed out that there is a leptin in human body, also known as anti-obesity factor, which is the main hormone to reduce hunger, and it controls our food preference. People who lack leptin like everything and eat a lot, so they finally become super fat. 7, diet: excessive calorie intake. Diet is still a very important factor affecting weight. Most people gain weight because they consume more calories from food than their bodies need. Therefore, eating less and exercising more is still a good way to lose weight. 8. Fat: To keep warm. If the weather is very hot, our appetite will decrease. People who use air conditioners are more likely to be obese because their heat regulation mechanism is blocked.
