In winter, people have a great appetite. There is a "thermostat" in the human body to control the body temperature within a certain range. When the external environment temperature drops, the body temperature will also change. In order to maintain body temperature, the body needs to consume more heat energy. In addition, cold weather promotes the secretion of gastric acid, making people more likely to have an appetite. ?
Fat anabolism is accelerated. Fat is not easy to transfer heat, and the fat distributed under the skin can reduce the heat loss in the body and prevent the invasion of external radiant heat. When the temperature drops, in order to maintain a constant temperature in the body, the human body will instinctively store more fat to resist the cold. At this time, the speed of human fat anabolism is 2~4 times faster than usual, while the speed of fat catabolism is lower than usual 10%. Lead to fat synthesis more than metabolism, fat accumulation, and then lead to obesity. ?
Eat while it's hot. When the weather gets cold, people like to eat some hot food to drive away the cold. Studies have proved that the temperature of food, especially the temperature of starch food, has an important influence on the digestion and absorption of food. Eating hot potatoes is 50% higher than eating cold potatoes. In other words, hot starchy foods have a higher glycemic index and can be converted into glucose faster, which is more conducive to digestion and absorption. The faster the food is digested, the weaker the satiety is. In order to achieve the same satiety, people will eat more food and consume more calories. Starch food will produce resistant starch after cooling, which belongs to dietary fiber and is a kind of carbohydrate that is not easy to digest and absorb, which can enhance satiety. ?
The amount of exercise is reduced. When the temperature drops, people's inertia begins to breed, and the amount of exercise is less, so the calorie intake is naturally less. In the case of more calorie intake and less consumption, the remaining calories will be converted into fat. ?
It gets dark early and doesn't go out. It gets dark early after winter, and it will be seven or eight after dinner. People are too lazy to go out and sit on the sofa and start watching TV and playing mobile phones. It leads to insufficient digestion of food and is the easiest to get fat. ?
Eat more sweets. Sweets are always irresistible. The sugar contained in it is digested faster than the complex carbohydrates in rice or bread and stays in the stomach for a short time. After eating, you will soon feel hungry. If you eat on an empty stomach for a long time, it will lead to a vicious circle. Furthermore, if the sugar in the blood increases rapidly, it will produce a lot of insulin to make fat, and people will easily get fat. ?
Wearing too much, ignoring your body shape. In summer, when your brawny arms are exposed, you will definitely urge yourself to lose weight. Wearing heavy clothes in winter is easy to ignore fat, even if you gain weight inadvertently, it is not easy to detect.
