To weight too less is a problem that one must seriously take care for it may be a symptom of a developing  disease. Whilst a balanced weight is desirable and healthy, too much meagreness is not.

To be overweight or obese is also a sign of malnutrition. It simply means that too much food is being taken for the body’s needs, and that excess is being stored as fat. Just the same as with too less weight, it must be dealt with gravity, because besides being poorly attractive, too much weight shortens life expectancy, increases the risk o heart diseases, diabetes and other.

The lack of physical exercise and sedentary occupation help to become obese, and this kind of lifestyle is more common in less younger people. But nobody is too old to lose weight.
