Is Keto Bad For Your Kidneys? Learn The Truth

Have you heard a keto diet might negatively impact your kidney health?

Many well-intentioned people warn about the potential dangers of eating a ketogenic diet. But is there any merit to these claims?

With so much conflicting information on the internet, it is hard to know what to believe. We’re here to tell you the straight truth about keto and your kidneys.

Keto Diet and Kidney Health Myths

You can find countless articles and videos warning you to avoid a ketogenic diet. As a result, people are often concerned about the health implications of a low-carb diet.

One of the primary concerns people have is whether or not a ketogenic diet is bad for the kidneys. Which is understandable, considering over 100,000 people experience kidney failure each year in the United States.

Due to the prevalence of kidney issues, many potential keto dieters are concerned about the following keto diet and kidney health myths.


Myth 1: Keto Diet is High in Protein

It’s a common belief that high-protein diets are hard on the kidneys. Limited research show high-protein diets are detrimental for those in late stage kidney failure. However, there isn’t any research showing high-protein diets are dangerous for those with healthy renal function.

With that said, even if high-protein was bad for the kidneys, a healthy ketogenic diet isn’t high in protein. The Keto Zone diet is high in healthy fat, low in carbs and moderate in protein.

So there isn’t any reason for concern about protein damaging your kidneys on a keto diet.


Myth 2: Keto Diet Causes Kidney Stones

Kidney stones form when mineral deposits crystalize together in the kidneys. The crystals primarily consist of insoluble calcium; other constituents include oxalates and uric acid. Since ketogenic diets cause an increased loss of electrolytes, some people speculate this can lead to kidney stone formation.

Yet, there isn’t any evidence to back this up claim.

In fact, most research shows low-carb diets generally improve kidney function. Which is especially true for those keto dieters who stay hydrated and make sure to keep their electrolyte levels up. On the Keto Zone diet we recommend that you drink enough water to stay hydrated. We also recommend that you supplement with electrolytes from Instant Ketones.


Myth 3: Ketosis = Ketoacidosis

Many people confuse ketosis and ketoacidosis. Ketoacidosis is a dangerous physiological state and occurs when you have high levels of both ketones and blood sugar, which causes the blood to become too acidic. As a result, damage can be done to the kidneys.

Ketoacidosis usually only occurs in those with Type 1 diabetes. If you have any insulin in your body at all, you will not go into ketoacidosis.

On the other hand, ketosis is completely safe and natural physiological state. Ketosis will not acidify your blood or damage your kidneys.

In fact, most research shows a ketogenic diet may actually support healthy kidney function! So then what actually causes kidney disease?


The Root Cause of Kidney Disease

The most common risk factor for kidney disease include:

  • Diabetes
  • Cardiovascular disease
  • High blood pressure
  • Smoking
  • Poor diet

The common factor connecting all of these risk factors is inflammation. Inflammation is at the root of most chronic disease, and kidney disease is no different.

Interestingly, a ketogenic diet can help prevent kidney damage by reducing systemic inflammation in the body. Meaning, keto is actually good for your kidneys.


The Truth: Keto is Good For Your Kidneys

You don’t need to worry about a ketogenic diet damaging your kidneys. In fact, a healthy low-carb diet is likely to improve your kidney health.

Due to the fat that ketosis will lower systemic inflammation, you can expect a keto diet to support your renal function.


The Bottom Line

Low-carb diets don’t damage your kidneys.

A healthy ketogenic diet is moderate in protein. Furthermore, even high-protein diets only cause kidney damage to those with advanced kidney disease.

If you keep electrolyte levels up and stay adequately hydrated, you don’t need to worry about kidney stones on a keto diet.

Ketosis and ketoacidosis are not the same thing. Ketosis is a perfectly safe and natural metabolic state that will not acidify your blood and cause kidney damage like ketoacidosis.

Above all, a healthy keto diet can lower systemic inflammation and actually lead to better overall kidney function.




  1. Thx Dr. Colbert!!!! I have had well meaning people I talk to that dont know what their saying but repeat what they have heard. I was told this the other day when telling people about your products and all. It’s funny how people get this and the bible all mixed up with hearsay and listening to one person. Thx for this as a time needed. Of course i have to clean up my inflamation myself and it’s good to hear this. Thx again…

  2. Hi! I have been on the Keto diet (working on getting all the correct foods). I have all the thyroind systems and about 40 years ago my eyebrows disappeared and a scar type tissue replaced them. I’ve tried tons of creams, etc. over the years. Not until I went on the thyroid pills starting this month have I seen anything. Now, here is what I want to tell you. I’m recovering from Bladder cancer and the works, but with the thyroid capsules I see tiny little hairs at the beginning of my brow. I’m so excited. If there is an e-mail address for the doctor I would like to forward a picture after a bit more progress. Also, I’m on baby aspirin for DVT it is my only pill plus vitamin D and magnesium for constipation. So far so good…….thanks.

  3. Thank You for that information. I have a friend who is dealing with a large stone and I told her about the Keto Zone Diet.

  4. Thanks for this information. I’m on dialysis, awaiting kidney transplant. All my labs are excellent. Thank you Jesus ☺️☺️☺️

  5. I have been on Keto for one and a half year. I now am on maintenance with an intake of around 60 carbs a day!
    However years ago I tried an all protein diet (dr. Still man) and I did develop a serious kidney infection. Never so on the Keto! Love the lifestyle. Thank you Dr. Colbert ! I have recommended your book to many people when they ask how I lost all my weight!
