The internal problem is that if the liver has hepatitis B, it is generally difficult to gain weight, and hoarding fat is also a reason for being thin. Some people say that being thin is due to eating less and malnutrition. This statement has some truth, but it is still not comprehensive. Indeed, many thin people are hungry by themselves, but there are still many thin people who eat a lot, but they don't grow meat. People are thin because of blood deficiency. Blood deficiency leads to fire. What is fire? Fire is an unnecessary gas. There is too much gas in the thin man's body, too much, far beyond the normal range. It is like a wheel, and its normal operation is 60 revolutions per minute. Qi deficiency, lack of power, the wheel can only turn 30 times per minute, so that fat accumulates. Too much gasoline and too much electricity. The wheel turns 120 revolutions per minute, which not only vaporizes what should be gasified, but also vaporizes what should not be gasified. The metabolism of thin people all presents a pathological hyperfunction state, so they are all blood deficiency and fire excess. Blood deficiency is the real cause of emaciation, and emaciation is the most obvious indication to judge a person's blood deficiency. The problem of being thin is more complicated than that of being fat. People who want to be fat have different situations. It can be roughly divided into four types: delicate type, malabsorption type, hypermetabolism type and fatigue type. How do thin people gain weight? Thin people are thin from childhood, with small bones and underdeveloped muscles. There is nothing wrong with them, but their resistance is slightly lower and their physical strength is slightly worse. Many young men and women belong to this type. Such people usually do little physical activity and lead a static life. Once people reach middle age, the fat in the waist and abdomen is easy to increase and evolve into a frog shape. Slim people want to change their body shape, they need to do anaerobic fitness exercises to increase their muscles, plus appropriate outdoor aerobic exercise. On the basis of exercise, increasing diet properly can improve body shape and enhance vitality. Boys can often do push-ups, and can also use fitness gadgets such as tensioners, push-ups and dumbbells to assist. Daily exercise can consider running, aerobics, fighting, swimming and so on. Swimming is especially beneficial to improve cardiopulmonary function, and it is of great help to delicate type. In terms of diet, it is suggested to increase the staple food, that is, starch food. Add nuts or dried fruit snacks between meals and a midnight snack at night. It is recommended to choose digestible foods such as yogurt, porridge, noodle soup and bread. How do thin people with malabsorption gain weight? People with malabsorption generally show lack of luster and thin body. The main problem is the poor digestion and absorption ability of the spleen and stomach. Some people have old stomach problems, some people have insufficient secretion of digestive enzymes, some people have gastroptosis, and so on. This kind of people must not rashly increase the high-energy diet, which will often overwhelm their digestive system. Some friends have heard that fat meat can make people fat, so they eat a lot of fat meat, which leads to vomiting and diarrhea, but they will lose weight. Others have heard that sweets can make people fat, and eating cakes with high fat and calories every day will make people lose their appetite for three meals, but the nutritional quality will decline. It is suggested that people with malabsorption should first see Chinese medicine to regulate the spleen and stomach. Eat digestible and non-greasy food, eat regularly, chew slowly when eating, concentrate and keep a good mood. Food should be cooked soft and warm on weekdays. If the stomach droops, it is recommended not to drink a lot of porridge soup and tea when eating, so as to reduce the burden on the stomach as much as possible. You can often drink fresh yogurt, eat bread, steamed bread, steamed cakes and other fermented pasta, as well as various fermented bean products. At the same time, do some gentle and relaxing exercises, such as walking, jogging, aerobics, ballroom dancing, Tai Ji Chuan and so on. Low-intensity exercise can relax the mood and improve digestion and absorption. Dream weaving, dream weaving, how can people with high metabolism be thin and fat, and those with high metabolism can also be called young type. Generally common in young men. They are healthy and energetic, don't like getting sick, and are warm, but they don't look so fat and have a small waist. This kind of person can't be called thin, because young men should be in a state of low fat content, and high levels of androgen make them have high basal metabolism level, tight muscles, love to eat and are not easy to gain weight. It's a pity if you had cream on your stomach when you were young-you're getting old early. Therefore, they don't need to gain weight at all. If you feel that your shoulders are not wide enough and your back is not thick enough, it is recommended to go to the gym for bodybuilding training. How can people who try to be thin gain weight? People who work hard tend to reach middle age. They have many things to worry about at work, poor sleep quality and hard work at home. Their brains and hands are not idle from morning till night. Energy consumption is high, and physical strength is overdrawn. It is useless for these people to simply eat more, because they have a bad appetite and poor digestion. The most important thing is to have a quiet rest for a while, stay away from troubles and relax. If possible, consult a health care professional for appropriate supplements. Hard-working people should do some aerobic exercise in the natural environment, which can improve blood circulation, reduce brain fatigue and improve sleep quality. For them, it is best not to exercise on the treadmill when they are tired from work. Because the air in the gym is often bad, the environment is crowded, and there are clear exercise goals and requirements, which is also a kind of pressure for tired people. If you want to exercise, you must do it with plenty of rest and energy. No matter what type, it should be clear that weight gain must be achieved on the basis of improving overall health and quality of life. If you can't improve your body by adding fat, this gain is meaningless and can only bring a burden to your body! Some people are born thin, don't eat anything and don't grow meat. They think too much under too much pressure and can't eat.
