Can I do Keto if I have a kidney disease?

A ketogenic diet is not a high protein diet, it's only consuming 3-6 oz of protein with each meal. There is a condition called ketoacidosis, which is different than nutritional ketosis, and your pH does not raise to any dangerous levels. Keto can also increase uric acid, but if you consume enough vegetables, again, you will be fine. Potassium in vegetables is very kidney protective, but high sugar and high insulin are damaging to the kidney more than anything else. Take a look at a diabetic - they usually end up with long-term kidney damage. GMO foods can also affect the kidney, so eat organic.
