concentration in the blood is low. Keith seems to have possible nerve problems. The doctor explains that Keith is pale due to anemic conditions brought on by the poor diet. With a poor protein diet, Keith's erythrocytes may not be making adequate hemoglobin. Because his diet is very low in carbohydrates, his body is metabolizing fat, which is causing the weight loss. By products of fat metabolism are ketones, which are acidic. This accounts for the increase in ketones in the urine and the blood and a drop in the pH.
