Does eating lots of salt and drinking ketones hurt your kidneys or blood pressure?
Acute Kidney Injury Markers and 24-Hour Blood Pressure after Short-Term High Salt and Ketone Supplementation in Apparently Healthy Adults

Surprising Findings
Higher serum creatinine was inversely correlated with systolic BP dipping, independent of salt or ketone intake.
Most assume BP dipping is only affected by salt, age, or disease—but here, even healthy people with slightly elevated creatinine (still in normal range) showed reduced nighttime BP drop, suggesting a hidden link between kidney markers and circulatory rhythm.
Practical Takeaways
If you're a healthy young adult, short-term high salt intake (like a week of salty meals) likely won't damage your kidneys or disrupt your nighttime blood pressure.

Eating more salt won’t make your blood pressure stay high over time if you’re otherwise healthy — your body adjusts and keeps things in balance.
In healthy young people, those with higher levels of a waste product called creatinine in their blood tend to have less of a nighttime drop in blood pressure—no matter how much salt they eat or if they take ketone supplements.
If healthy young adults eat a lot of salt and take ketone supplements for 10 days, their kidneys don’t show any signs of stress or damage based on common blood and urine tests.
Eating a lot of salt for a short time or taking ketone supplements won’t change how much your blood pressure drops at night if you’re a healthy young adult.
