Graph showing effect of dietary protein restriction on progression of diabetic nephropathy

Dietary protein restriction - to about 0.6 g/kg per day or 30 to 40 percent lower than the control group - in two trials (left and right panels) of patients with type 1 diabetes and diabetic nephropathy led to a 75 percent reduction in the rate of loss of glomerular filtration rate (GFR) at 18 to 36 months.
