First of all, increase the number of meals, in addition to the normal three meals, you can add two or three simple meals. Secondly, you can eat snacks properly and choose foods with higher energy as snacks. In addition, moderate exercise is needed to help digestion and absorption of food. Finally, we should pay attention to adjusting our mood, keeping our mind at peace and ensuring adequate sleep. The elderly are thin, so they can help to gain weight through diet conditioning. Because the gastrointestinal peristalsis of the elderly is relatively slow, and the metabolic level of the body is also relatively slow, they can eat more foods that can help stimulate appetite, invigorate the spleen, tonify the kidney and replenish qi, such as yam, chestnut, pumpkin, deep-sea fish and high-quality protein. Yam, in particular, can help strengthen resistance, strengthen the spleen and lung, and strengthen the body.

There is an old saying in China that "the heart is broad and the body is fat". Only when you have a good attitude can you gain weight smoothly. Therefore, if you are too thin and want to gain weight, you must adjust your attitude and keep a good mood every day. In this way, if you have a good mental state and a good appetite, you will eat more and more, and the purpose of gaining weight can be successfully completed. If you are depressed for a long time, it will be difficult to gain weight. Thinning is a symbol of human aging. Many elderly people lose weight not because of fat loss, but because of the decline of muscle quality and function. This muscle degeneration symptom is called sarcopenia. When people enter old age, with the increase of age, the secretion of sex hormones decreases, which makes the ability of muscle synthesis insufficient and the incidence of sarcopenia increases. It has been reported that the incidence of sarcopenia is 5%~ 13% in people aged 60~70, while it is 1 1%~50% in people over 80. Excessive emaciation of the elderly may also be caused by diseases. Neurological diseases can lead to malnutrition, inflammation, infection, malignant tumors and other consumptive diseases, which greatly increase the energy consumption of the human body, thus causing emaciation.
