The Claim

Among Japanese adults with diabetic kidney disease, the rate of eGFR decline on a low-carbohydrate diet is −0.26 mL/min/1.73m²/year, which is slower than the average rate of −0.36 mL/min/1.73m²/year observed in the general Japanese adult population.

In plain English

In Japanese adults with diabetic kidney disease, a low-carbohydrate diet is associated with a slower decline in kidney function (eGFR) compared to the average decline seen in the general Japanese adult population.

See the scientific wording

Among Japanese adults with diabetic kidney disease, the eGFR decline rate on a low-carbohydrate diet (−0.26 mL/min/1.73m²/year) is slower than the average decline rate reported in the general Japanese adult population (−0.36 mL/min/1.73m²/year), suggesting potential stability despite higher protein intake.

Why this might work

When carbohydrate intake is low, blood sugar and insulin levels stay lower, which reduces the pressure inside the kidney's filtering units. This lessens the strain on damaged filters, slowing down their breakdown.

  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 fewer carbs lost kidney function at a rate of −0.26 per year, which is slower than the average −0.36 seen in regular Japanese adults — even though they ate more protein. This suggests their diet might be helping protect their kidneys.
