The Claim

In Japanese adults with diabetic kidney disease, a low-carbohydrate diet providing 70–130 g/day of available carbohydrates is associated with a protein intake of 1.2 g/kg/day, compared to 1.0 g/kg/day with an energy-restricted diet, without a greater rate of eGFR decline over four years.

In plain English

Among Japanese adults with diabetic kidney disease, eating a low-carbohydrate diet with 70–130 grams of available carbs per day results in higher protein intake (1.2 grams per kilogram of body weight) than an energy-restricted diet (1.0 grams per kilogram), and the rate of kidney function decline over four years is similar between the two diets.

See the scientific wording

In Japanese adults with diabetic kidney disease, a low-carbohydrate diet achieving 70–130 g/day of available carbohydrates is associated with significantly higher protein intake (1.2 g/kg/day) compared to an energy-restricted diet (1.0 g/kg/day), without a corresponding increase in eGFR decline over four years.

Why this might work

When more protein is eaten, the kidneys adjust how they process waste by tightening filtration in the filtering units and reducing stress on the blood vessels, so the kidneys keep working normally even with higher protein levels.

  1. Study: Renal function trajectories of Japanese adults with diabetic kidney disease on different diet therapies including energy-restricted and low-carbohydrate diets: a retrospective cohort study

    People with diabetic kidney disease who ate more protein on a low-carb diet didn’t lose kidney function any faster than those on a low-calorie diet with less protein. So, eating more protein didn’t hurt their kidneys over four years.
