Disease is the potential effect of emaciation. Such as thyroid, diabetes, adrenal gland and digestive system diseases. Common diseases leading to emaciation include intestinal parasites, long-term active tuberculosis, anemia, diabetes, hyperthyroidism, malignant tumor, pituitary hypofunction and some metabolic diseases. Genetic factors and parents' obesity have a far-reaching impact on children. The centimeter of height minus 100 times 0.9 equals my standard weight. Ways to gain weight-first, increase the intake of meals, which are rich and varied. Eating more is the material basis for gaining weight. Chew slowly, don't be picky about food or partial eclipse, and try to make the food delicious, which is the guarantee of eating more. Protein should eat more foods rich in fat and carbohydrates (starch, sugar, etc.) when it has sufficient intake. In this way, excess energy can be converted into fat and stored under the skin, enriching and thinning. Fat appetizing food: beef, honey, lotus root, ginseng, etc. , as well as pomfret, mutton, pork belly, chicken and duck meat, milk, eggs and potatoes. In terms of diet, a high-protein and high-calorie diet is the only way to gain weight. Concentrated protein and high-calorie foods, such as heavy cheesecake, small cakes, small cakes, etc. Papain or comprehensive enzymes should be supplemented in time after meals to help digestion, so as to increase the digestion, absorption and utilization of food. Drinking Xiaoqing lemon juice can promote the rapid digestion of food. Thin people often have yin deficiency, less blood and less body fluid, so they should eat more nourishing body fluids in their diet, such as milk, honey, eggs, soft-shelled turtle (turtle), sea cucumber and tremella. Commonly used effective dietotherapy prescriptions are: walnut milk drink, honey drink, sea cucumber paste, turtle meat lily red date soup, turtle kidney nourishing soup, Shenmai turtle, tremella pigeon egg, lily chicken yellow soup and so on. Yin deficiency often leads to internal heat, and thin people often have endogenous phenomena such as irritability, dry mouth and sore throat, and hypersexuality. Therefore, while nourishing, we should also pay attention to clearing the deficiency fire, and choose to eat clam Maimendong soup and chrysanthemum slices. Sugar intake is also an important part. Choose foods with high starch content, such as white toast, steamed bread, white rice, sweet potato, taro and pumpkin. When cooking, you can add some maltodextrin (commonly known as corn hydrolyzed starch, which can be eaten directly in food) in the form of glutinous rice, soup or thick soup, or in soup or juice and milk to increase calorie intake. In the oil part, medium-chain fatty acids with good absorption and utilization rate can be used in moderation to increase the intake of concentrated calories. Pure medium-chain fatty acids need to be used with general oils and fats because they do not contain "essential fatty acids". It is suggested to use medium-chain fatty acid products to mix essential fatty acids (such as sanduo high energy) to avoid the lack of essential fatty acids. It is generally recommended that medium-chain fatty acids account for 60% of the total oil consumption. Second, we should keep adequate and good sleep. If people get enough sleep, their appetite is better, which is also beneficial to the digestion and absorption of food. Third, proper sports and leisure activities. The food you eat is converted into muscle, not fat, which can be digested and absorbed. Exercise is the key. The exercise of people who want to gain weight is mainly "weight training", rather than "aerobic exercise" emphasized by people who lose weight. Because "aerobic exercise" promotes energy consumption, and "weight training" is used to increase the proportion of muscles. With the help of dumbbells, barbells and training equipment, combined with the complete contraction and relaxation of large muscle groups, muscle construction can be realized. In terms of exercise mode, jogging is a good choice, because the number of gastrointestinal peristalsis increases obviously when people jog, which can consume human energy and make people have a big appetite when eating. Generally speaking, a large amount of exercise, short-term exercise and rapid explosive exercise can all have the effect of gaining weight, which is also the most taboo for people who want to lose weight. When doing bodybuilding, it is best to take less part in other sports, especially endurance sports, such as long-distance running, playing football and basketball. Because these exercises consume more energy, which is not conducive to muscle growth and will become thinner and thinner. Besides, don't do other activities that consume too much energy. Taboo-1. Don't eat spicy food. 2. Try to avoid fried food. Smoking, alcohol and coffee should be restricted. 4. Don't stay up late.
