It is necessary for thin people to gain weight. Fattening is not only to appropriately increase the subcutaneous fat of the body, but also to make muscles and physique stronger. That is to correct not only "thinness" but also "weakness". So, how should thin people gain weight correctly?

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. 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.
