The Claim

In healthy obese adults, a 24-month low-carbohydrate high-protein diet has no clinically significant effect on serum electrolyte levels (sodium, potassium, chloride, bicarbonate) compared to a low-fat diet.

Source: Comparative effects of low-carbohydrate high-protein versus low-fat diets on the kidney.

Description
1 study reviewed
In plain English

In healthy obese adults, following a low-carbohydrate high-protein diet for two years does not change blood levels of sodium, potassium, chloride, or bicarbonate compared to a low-fat diet.

See the scientific wording

In healthy obese adults, a low-carbohydrate high-protein diet for 24 months does not impair serum electrolyte balance (sodium, potassium, chloride, bicarbonate) compared to a low-fat diet, indicating that metabolic acidosis or electrolyte disturbances are not common consequences of this dietary pattern in this population.

Why this might work

When a person eats a lot of protein, the body breaks it down into waste products like urea and sulfuric acid. The kidneys filter out these wastes in larger amounts, pulling more water with them to flush everything out. This increased urine flow does not remove sodium, potassium, or chloride from the blood because the kidneys adjust how much of these salts are reabsorbed back into the body. The body also balances acid levels by using buffers and adjusting how much bicarbonate is retained, so the blood stays at a normal pH and electrolyte levels stay stable.

1 study
  1. Study: Comparative effects of low-carbohydrate high-protein versus low-fat diets on the kidney.

    The study found that eating a low-carb, high-protein diet for two years didn’t mess up the levels of important salts in the blood, like sodium and potassium, in obese adults — same as a low-fat diet.
