hereditary thin, and the BMI value is rarely lower than 18
. Some thin people belong to “hereditary thin”. Dr. Kuang Jian, chief physician of Endocrinology Department of Guangdong Provincial People’s Hospital, said: “in the long process of human evolution, Most people’s genes have evolved to store calories quickly. Only a few people have genes that are not good at storing calories, so they don’t get fat anyway. ” The health status of hereditary thin people is normal, and their BMI is rarely lower than 18. BMI = weight (kg) divided by the square of height (m), which is the current international standard to measure the degree of obesity and thinness of adults.
people with BMI < 18 are abnormally thin
people with BMI less than 18 are abnormally thin, and the reason must be found. According to the statistics of the medical community, the average life span of people who are too thin is slightly lower than that of people with normal weight, and they are relatively more prone to gastroptosis and nephroptosis due to too little fat, and the recovery speed after illness is also slower than that of ordinary people.
people become fat and thin according to a law:
dietary intake of calories > exercise consumption = fat storage
dietary intake of calories < exercise consumption = fat consumption
. Therefore, the following three factors determine a person’s fat and thin: a. Is there any disease that prevents the body from absorbing or consuming too much energy; B。 Whether the dietary calorie intake is sufficient; C。 Whether the amount of exercise is too large. Many thin people always say that I don’t have any reason, that is, I don’t eat fat. In fact, I don’t seriously look for the reason. The common reasons for getting fat are different at different ages.
children
parents should consider whether the child has worms? Insect bearing children can’t sleep well and grind their teeth at night. Weight loss is caused by poor appetite after infection with insects, and food is not absorbed by the body. Intestinal worms used to be more related to poor sanitary conditions. The current disease is more likely to be related to keeping pets and eating raw fish.
in addition, if children eat a partial diet, such as eating only meat or vegetables, of course, they will not get fat. Parents must improve their eating habits and let their children eat a balanced diet.
adults
1. Improper diet
whether some people grow fat is caused by poor eating habits“ Clinically, some people deliberately avoid eating when they are ill. ” Kuang Jian said he had received a pair of middle-aged and elderly couples. He continued to lose weight for six months. He carefully asked about diabetes and increased exercise. He only ate vegetables and milk, and seldom consumed starch food. Another patient’s relatives and friends got diabetes. He was afraid that he was sick. He would restrict himself to diet and exercise a lot, and of course he would lose weight. Some diseases require diet restriction, but this is to reduce the intake on the premise of ensuring nutrition “.
2. Excessive weight loss
some beauty loving women take weight-loss pills indiscriminately, become anorexia and lose weight day by day. He once received a female student who was 1.6 meters but weighed only more than 60 kilograms. Anorexia was caused by excessive diet“ Anorexia is a disease caused by neurological abnormalities. Patients don’t have any appetite at all. ” Kuang Jian said that some irregular weight-loss drugs on the market will inhibit the central nervous system, affect appetite, as well as side effects such as depression and accelerated heart rate.
3. disease factors
high metabolic diseases and chronic wasting diseases all affect weight, such as tuberculosis, diabetes, thyroid diseases, tumors and so on. For example, in patients with hyperthyroidism, the symptoms are exophthalmos, palpitation, irritability, overeating, sweating, etc; If you like to eat fish and have pets, consider whether there are insects; Whether suffering from gastrointestinal diseases, such as stomach disease, it is uncomfortable to eat; Anxiety patients do not rest well, consumption will increase, and people will lose weight; Female menopause is in a state of continuous high metabolism and is easy to lose weight. Chronic diseases are common in middle-aged and old people, such as diabetes can cause weight loss, Kuang Jian reminds: “diabetes patients such as poor blood sugar control, resistance will be weakened, prone to tuberculosis and other infectious diseases, we should pay attention to.”
after these diseases are cured, they will soon get fat. Others are not ill, but often stay up late to work, which will consume a lot of body and lose weight. To remind you that if a fat person suddenly becomes thin, you have to rule out the factors of disease.
■ fattening Baodian
general: moderately reduce the amount of exercise, eat a little more on the basis of balanced nutrition, so that the intake exceeds the consumption. In terms of diet, fattening people should increase the intake of starch staple foods and high protein foods (fish, meat, eggs and milk). Measure the weight once a month, detect the change of weight and adjust the diet.
the weight remains unchanged: the amount of exercise remains unchanged. Eat more.
body weight is still declining: it may be excessive exercise, high consumption, insufficient dietary intake, or untreated primary diseases.
relaxed attitude, regular exercise, balanced nutrition, good rest, timely prevention and treatment of diseases are the key to maintaining normal weight.
