A reasonable diet is of course important. There are many reasons for being thin. In fact, this is not because of poor health. It may be caused by deficiency of qi and blood or bad spleen and stomach, and a small part of it is caused by unbalanced nutrition. It may also be because of genetic problems that such people are not fat. I have a friend who is in this situation. However, since eating Taobao Chinese medicine, the shopkeeper's appetite has gradually improved, his physique has gradually strengthened, and his stomach absorption function has gradually improved, and he has begun to become better than before, from 70 kg to 90 kg now. Compared with the previous thin man, he will become healthier and look better. Internal training is the best way.
