The statement has frequently been made by different clinicians that cases of diabetes usually feel better and are better protected against the dangers of diabetes if they are fat above the average. It has also been stated that diabetics do not tolerate reduction cures very well. I have myself expressed similar views in another place. It is clear therefore that cases of diabetes that are suffering from slight degrees of obesity should never undergo a reduction cure, and that cases suffering from medium degrees of obesity should undergo reduction cures only under exceptional circumstances. This does not, however, exclude the necessity of reducing fat in cases of diabetes that are very obese and in whom the excessive fat content of the body directly endangers the life of the patient. In certain cases diabetes may be complicated by attacks of heart failure (in patients afflicted with valvular lesions, arteriosclerosis, contracted kidney and simple cardiac weakness). Patients of this character should be relieved of any excess of fat even if the obesity is only of medium degree; only in this way can the heart be protected from excessive strain. I could quote numerous examples to illustrate the point I am making, namely, that reduction cures are not necessarily always counter-indicated in every case of diabetes. The experience of the physicians of Carlsbad and of Marienbad also supports this position. In regard to the best method to be adopted, we must always remember that diabetes tolerates neither long continued reduction of flesh nor, on the other hand, sudden loss of weight and reduction of fat. The best way to produce the desired result in these cases is to institute in termittent reduction cures; in other words, two or three pounds at the utmost should be made to disappear in the course of three or four weeks; this reduction treatment should be repeated every three months. The reduction of fat should never be carried further than is absolutely necessary for the conservation and the protection of important vital functions.
