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.
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.
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.
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.
What the research says
1 studyPeople 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.
