Warning for those who are in the second year of Corona 19 … ‘We need to manage weight through indoor exercise and diet control’

The second winter has arrived since the COVID-19 pandemic. As the frequency of going out has decreased due to the prolonged Corona 19 and the application of vaccine passes to indoor sports facilities, the number of people who are inevitably unable to exercise is increasing.

According to the Korean Obesity Society’s “National Weight Management Status and Obesity Awareness Survey in the Era of Corona 19,” 4 out of 10 Koreans gained 3kg or more in weight compared to before Corona 19. By age, weight increased in the order of 30s, 40s, and 20s, and it was found that females (51%) gained more weight than males (42%).

As the frequency of going out has decreased due to the sudden cold, it is necessary to pay more attention to managing body fat and obesity. When the metabolic function is lowered due to cold weather, the concentration is reduced and the amount of activity naturally decreases due to the feeling of fatigue easily. There is also a report that 51 minutes (121 kcal) for men and 16 minutes (70 kcal) for women decrease physical activity. In addition, as winter approaches, the amount of sunlight decreases, reducing daytime activity and increasing indoor life naturally. On the other hand, winter is a time when preference for warm, fatty, high-fat food increases, and year-end gatherings and banquets are frequent. As the amount of physical activity decreases compared to the amount of food eaten, body fat is inevitably accumulated.

Obesity is not simply being overweight, but rather a condition in which more fat is accumulated than normal. Age, lifestyle, and eating habits act in a complex way, which can lead to diseases such as high blood pressure, fatty liver, dyslipidemia, and coronary artery disease, so it must be managed.

You need to correct your eating habits and lifestyle and gradually increase physical activity that suits you.

Hyerim Hwang, head of the comprehensive examination center at Daedong Hospital (specialist in family medicine) said, “In order to prevent infection or to avoid the cold, we have no choice but to do a lot of indoor activities, but it is important to be aware that body fat can accumulate and lead to diseases. good,” he advised. According to Hwang, in order to prevent obesity in winter, it is recommended to increase the body temperature by doubling the usual warm-up exercises and loosen the muscles. Avoid exercising at dawn or in the evening when the temperature is low, and indoor exercise is recommended, especially for the elderly and people with underlying diseases. However, when exercising indoors, it is necessary to ventilate the room frequently to prevent the spread of COVID-19. If you don’t have any special health problems, whenever you get a chance, it’s helpful to protect yourself with a hat, scarf, etc., and then go for a walk outdoors.

When adjusting your diet to lose weight, you should reduce your calorie intake, but eat evenly so that you do not lack essential nutrients that control body functions, such as carbohydrates, proteins, and fats. Avoid eating fatty foods and eat plenty of fruits and vegetables that are high in fiber.
