I didn't know that. Where did you get that info from?
I found this on dietdoctor.com :
7. Can low carb damage your kidneys?
Highly unlikely.
Many people still believe that a low-carb diet necessarily is very high in protein, that could put a strain on the kidneys. This is a myth based on two misunderstandings.
First, a well-formulated low-carb diet is high in fat, not protein. The amount of protein – like meat – should be moderate, just like in most diets.
There's no benefit of eating excessive amounts of protein. It can even be detrimental on a low-carb diet, as excess protein can be converted to glucose, just like most dietary carbohydrates.
As a low-carb diet shouldn't be very high in protein, the whole "problem" behind this controversy simply does not exist.
Secondly, people with normal kidney function can handle high amounts of protein without any problem for the kidneys.
Even if people choose to eat excessive protein, this will only be a problem if the kidneys are already severely damaged. An example of this would be end-stage kidney disease that is close to requiring dialysis. Basically, if you have severe kidney disease and you've been told to limit protein, you should of course do so.
But that would still make it possible for you to successfully eat a low-carb, high-fat diet.
In fact, by lowering elevated blood sugars a low-carb diet may actually protect the kidneys from one of the most common causes of damage. Especially for people with diabetes, low carb might help protect their kidneys, by helping control their blood sugar levels
What do you think about that? I'm not a dietician nor a doctor so I honestly don't know. That's why I'm asking ^^
I'm skeptical of the source you got that from. Carbohydrates are the only source of energy other than oxygen we get, glucose is the primary source of energy for the brain and muscles. Through the documented process of starvation, once the glycogen reserves are emptied the liver synthesizes protein and fat cells to create glucose (aka carbs). That fact alone I think discredits low carb diets.
Because all plants have carbs, low carb diets are mainly cutting out starches, fruit, grain, and dark leafy vegetables. The high restrictions greatly put people at risk of deficencies in micro-nutrients, fiber, phyto-nutrient, anti-oxidants, etc. which increases the chances and severity of chronic diseased such as diabetes, cancer, hypertension, atherosclerosis, etc.
The only foods high in fat are meat, dairy, nuts, and seeds (not to mention refined vegetable oil). I highly doubt these diets are having people eat 500-1000 calories of nuts and seeds, so the idea of "moderate protein" is dishonest, to say the least.
Carbs and even refined fructose can't cause diabetes or obesity alone, and I'm moreso speaking about refined fructose, a high-carb diet is practically heart attack proof. What causes the insulin resistance is that excess fat stored in the cell blocks the insulin receptors making it difficult for the insulin to enter and exit the cell. The sugar can't stay in the bloodstream so the liver excretes more and more insulin to stabilize the body, this loops until the liver can no longer produce enough insulin to stabilize the blood sugar. Refined fructose AND saturated fat cause diabetes, not either one exclusively, like a spark and oil. Physiologically, humans cannot efficiently convert sugar to fat, it's just not possible. The fat you wear is the fat you eat.
Nothing I've said can't be found in a medical textbook, though some studies may not have been updated to it yet.
Add-on: The presence of non-alchoholic fatty liver disease as the most common liver disease in the world debunks that claim. Most American's liver's and kidney's are over-stressed which is partly because the SAD gives you 3x the daily recommended amount of protein a day. "Average" or "moderate" protein intake is high, yet most Americans are deficient in fiber, the priorities are completely distorted.
