Kidney stones are a concern for some keto practitioners, particularly those following therapeutic (very high fat) versions of the diet. With smart dietary choices, this risk can be significantly minimised.
Uric acid stones: risk slightly elevated on keto due to temporary uric acid increase during adaptation. Calcium oxalate stones (the most common type): risk depends on oxalate intake and hydration, not specifically keto. Calcium phosphate stones: not specifically keto-related.
Drink at least 2.5 litres of water daily. Higher urine output dramatically reduces stone formation risk for all stone types.
Spinach, almonds, and beet greens are high in oxalate. Rotation rather than elimination: eat varied vegetables rather than spinach every day.
Include base-forming foods (leafy greens, citrus juice in small amounts) to maintain urine pH above 5.5, reducing uric acid crystal formation.
