The causes of emaciation are: mental factors, emotional factors, mental anxiety, irregular life, overwork, lack of sleep, and physical exertion exceeding intake, which will all cause emaciation. Dietary factors, irregular diet, lack of physical exercise, lack of nutrition, especially the lack of protein ingredients are more likely to cause.

Of course, there is pathological emaciation (caused by diseases). The common diseases that lead to emaciation include intestinal parasites, long-term active tuberculosis, anemia, diabetes, hyperthyroidism, malignant tumors, pituitary dysfunction and some metabolic diseases.

So in this case, you'd better go to a specialist for examination to see if there are any pathological factors. After excluding pathological factors, we should pay attention to: dietary distribution must be reasonable and diverse, not partial eclipse. Usually, in addition to eating meat, eggs and poultry rich in animal protein, we should eat more foods rich in fat and carbohydrates (starch, sugar, etc.). ). In this way, excess energy can be converted into fat and stored under the skin, making thin people plump. Of course, eat more soy products, red beans, lilies, vegetables, fruits and so on. Only a comprehensive diet is conducive to digestion and absorption. I hope I can help you!

You can combine dieting and weight gain with exercise. Foods that can gain weight are generally delicious and sweet. If you pay attention to eating high-fat and high-sugar foods three times a day, it is easy to get fat. But when eating, we should pay attention to choosing beneficial food, otherwise we will force more meals, so that the appetite will gradually increase. When your appetite increases, with proper exercise, you will see that your body and limbs will gradually become stout and your body will not look so thin.

First of all, see if your current weight really needs to gain weight. If you don't have chronic wasting disease, you really need to gain weight. The following suggestions are for reference:

When the human body consumes more calories than it does, the body begins to convert the remaining calories into fat and store them. This is the principle of weight gain.

Specifically, when the total amount of food remains unchanged, the more high-calorie things you eat, the closer your diet is to oil, and the higher your calories are. Food is divided into four grades according to the proportion of weight and calories. This concept is called "calorie density" (CD, unit: calories/gram). The lower the calories per unit weight, the less calories people consume after eating, which is good for losing weight. On the contrary, foods with high calories per unit weight are beneficial to gain weight after eating a lot of calories. Specifically, four-star food, that is, the calorie density is between 0 and 0.6 calories/gram, three-star food is between 0.6 and 1.5, two-star food, 1.5 to 4, 1 star food, and 4 to 9. 9 calories/gram, it is basically pure oil. Vegetables and fruits are mostly 4-star foods, and snacks are mostly 1 star foods.

In terms of quantity, eating more is the easiest way to gain weight. Snacks with high calories between meals should not be idle while watching TV. Don't stand when you can lie down, and try to consume as little calories as possible. If you stick to this for a few months, you will gain weight.

First of all, we should increase dietary intake, gain weight, and provide the body with all kinds of nutrients needed to synthesize tissues. The diet should be rich and varied, not picky eaters or partial eclipse, and the food should be as delicious as possible. In the case of adequate intake in protein, it is advisable to eat more foods rich in fat and carbohydrates. In this way, excess energy can be converted into fat and stored under the skin, enriching and thinning.

Secondly, we should keep enough and good sleep. If people get enough sleep, their appetite will be better.

Finally, exercise properly. Take some time to exercise every day, which will not only improve your appetite, but also make your muscles stronger and stronger. If you don't exercise for a long time, your muscles will "go in and go out", and your muscle fibers will shrink and weaken, making you look very thin. Intellectuals are mostly of this size, so we should pay attention to strengthening exercise.

Answer: First of all, we should increase our dietary intake, gain weight, and provide the body with all kinds of nutrients needed to synthesize tissues. The diet should be rich and varied, not picky eaters or partial eclipse, and the food should be as delicious as possible. 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.

Secondly, we should keep enough 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 exercise. Especially for people who sit in the office for a long time, taking some time to exercise every day will not only help to improve their appetite, but also make their muscles stronger and stronger. If the muscles of the human body do not exercise for a long time, they will be "used in and wasted", and the muscle fibers will contract and weaken relatively, making people look thin. Intellectuals are mostly of this size, so we should pay attention to strengthening exercise.

In addition, people who have been seriously emaciated for a long time should go to the hospital for physical examination while taking measures such as strengthening nutrition and doing more exercise to eliminate possible diseases in the body. Common diseases leading to emaciation include intestinal parasites, long-term active tuberculosis, anemia, diabetes, hyperthyroidism, malignant tumor, pituitary hypofunction and some metabolic diseases.
