If "thin" has always belonged to the normal weight range, this statement is correct. At this time, the concept of "getting thinner when you are old" is a sign of health, which means that the elderly should not be overweight. Overweight often induces hypertension, hyperlipidemia, coronary heart disease, diabetes and cerebral arteriosclerosis, which brings great harm to health.
If "thin" belongs to the abnormal range of weight, that is, "too thin", this statement is not appropriate. Because being too thin suggests malnutrition, decreased resistance and susceptibility to diseases, it cannot be understood that the elderly will be healthy as long as they are thin, nor can it be misunderstood that the lighter the weight, the better. Because the teeth of the elderly are constantly falling off, the gastrointestinal digestive function is gradually weakened, and other organs are aging, it is particularly important to ensure adequate nutrition so that all organs and tissues of the body can operate normally. In this case, it is unreasonable to strengthen nutrition and pursue "old and thin".
If "thin" comes suddenly in half a year or less, this statement is wrong. Because this thinness must be a dangerous signal that the body is suffering from diseases, and it is a manifestation of the decline of physical function. Seeing this situation, the elderly must go to the hospital in time, find out the reasons for being thin and actively treat them.
It can be seen that being too fat is unhealthy, and being too thin will also affect your health. We should know that the degree of physical obesity naturally formed in our own lives is often the most suitable for the elderly themselves, so as to guide the elderly to live a long and healthy life. Therefore, as long as it is not too fat, too thin or suddenly fat and thin, it is the best in the normal weight range.
