The Claim
Low insulin levels resulting from carbohydrate restriction reduce renal sodium reabsorption, leading to increased urinary sodium excretion.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When carbohydrate intake is reduced and insulin levels drop, the kidneys excrete more sodium in the urine.
See the scientific wording
Low insulin levels resulting from carbohydrate restriction reduce renal sodium reabsorption, leading to increased urinary sodium excretion.
When insulin levels drop, the kidneys stop reabsorbing as much salt from the urine, so more salt gets flushed out. This happens because low insulin reduces a signaling molecule inside kidney cells that normally turns on a salt pump. Without that signal, the pump slows down, so salt stays in the urine instead of going back into the blood.
What the research says
1 studyWhen people take ketone supplements, their kidneys flush out more salt in the urine—even without eating fewer carbs. This matches the idea that low insulin (from low-carb diets) makes the body pee out more salt, so the study supports the claim indirectly.
