Medical Disclaimer: People with pre-existing kidney disease should consult a nephrologist before starting keto. This article is for informational purposes only.
One of the most persistent concerns about keto is that it damages kidneys. The evidence tells a different, largely reassuring story for people with healthy kidneys.
Keto is often confused with very high-protein diets. Moderate protein — which keto requires — does not stress healthy kidneys. It is excessive protein over many years that concerns nephrologists.
Keto can temporarily raise uric acid levels, which could theoretically increase kidney stone risk. Staying well hydrated and consuming adequate alkaline vegetables mitigates this risk substantially.
People with CKD (chronic kidney disease) stage 3+ should not follow keto without nephrology guidance. Protein and potassium restriction is often required in advanced kidney disease, conflicting with standard keto advice.
Drink 2–3 litres of water daily, include plenty of low-carb vegetables, and avoid excessive protein. Our keto salads and keto main dishes feature kidney-friendly ingredient profiles.
