Yep! that's pretty spot on. Fat also stores toxins which is released when fat is burned.
Here is a bit more info on ketoacidosis and kidney function.
Wise words from Doreen on ketoacidosis:
"Ketoacidosis is a dangerous condition that happens in uncontrolled diabetes, and the main element is ACID not ketones. The blood pH becomes dangerously acidic because of an extremely high blood SUGAR level (the diabetic has no insulin, or doesn't respond to insulin .... so blood sugar rises ... ketones are produced by the body to provide the fuel necessary for life, since the cells can't use the sugar). It's the high blood sugar, and the acid condition that is so dangerous. Ketones just happen to be a part of the picture, and are a RESULT of the condition, not the CAUSE.
Being in ketosis by following a low carbohydrate diet is NOT dangerous. The human body was designed to use ketones very efficiently as fuel in the absence of glucose. Ketogenic diets have been used very successfully to treat epilepsy in small children, even as young as one year old ... these kids stay on the low-carb, moderate protein, high-fat diet often for years at a time .. with no adverse effect on growth, development or intelligence. And their seizures are controlled ... where toxic drugs failed."
And on kidney damage from
atkinscenter.com
"Studies show that the glomerular filtration rate (GFR) goes up with a high protein intake. The GFR is a measure of how efficiently the kidneys are filtering protein and other byproducts of metabolism from the blood. A high GFR may seem bad to some dietitians but, in fact, it is actually a sign of excellent kidney function. It simply means the kidneys are capable of doing a job beyond their usual requirements. Think of this analogy: Aerobic exercise raises your heart rate, yet everyone acknowledges that, because aerobic exercise raises the heart rate, it strengthens the heart. In our clinical practice, we have seen thousands of patients over three decades, and we have never seen a single case of a high-protein eating program causing kidney damage."
