Since the diet is high in proteins, one with advanced kidney disease should be very cautious on this diet, and should work closely with doctors. In fact, one with advanced kidney disease might even avoid it, since in this case the kidneys have trouble handling high loads of proteins in the diet. The diet, however, will not cause kidney disease in one with healthy kidneys- in fact; it may even prevent it according to numerous studies on atherosclerosis, the usual cause of kidney damage (A.V. Constantini 1994).
Also, those who are pregnant, breast feeding, or are in childhood years may not be suited to this type of diet due to the relative lack of carbohydrates. Those who exercise vigorously may also not do well on a diet that is severely restricted in carbohydrates. If you fit any of these categories, it should be discussed with the physician or nutritional counselor.
