low GI and low GL diet have more beneficial effect for diabetic nephropath patients compared with conventional diet.
low GL may have more favorable effect than low GI diet.
According to body weight status of participants, the investigators considered a slight calorie restriction ranged from 200 to 300 Kcal/d. Planed meals and exchange list prescribed for all volunteers. Dietary records forms were given to all subjects and they were educated how to record their dietary intakes. The investigators asked subjects not to change their physical activity level during the study and monitored them for their physical activity level by 3 days physical activity records monthly.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| low GI | Experimental | low GI: participants were asked to consume low GI foods (GI<55) in abundant, medium GI in moderate and high GI (GI>70) rarely. |
|
| low GL | Experimental | low GL: participants were asked to consume low GI foods and the amount of carbohydrate was controlled. |
|
| conventional diet | Experimental | conventional diet: all carbohydrate were treated as the same. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| low GI | Other | All diets were designed with similar macronutrients content (30% fat, 0.8 g/kg/d protein and remained calorie requirement by carbohydrate). Additionally, we controlled phosphorus, sodium and potassium content of diets for three intervention groups. All dietary menus had less than 1500 mg phosphor and less than 2400 mg sodium and 2000 mg potassium. |
| Measure | Description | Time Frame |
|---|---|---|
| Serum creatinine (and blood urea nitrogen (BUN) (mg/dL) were measured by colorimetric method and enzymatic colorimetric method using commercial assay kit. | baseline, wk 12 |
| Measure | Description | Time Frame |
|---|---|---|
| Serum levels of high sensitive C- reactive protein (hs-CRP) (mg/L) were quantified by using an ultrasensitive latex-enhanced immunoturbidimetric assay (Randox Laboratory Ltd., Belfast, United Kingdom). | baseline, wk 12 |
| Measure | Description | Time Frame |
|---|---|---|
| Fasting blood sugar (FBS) and lipid profile concentrations (mg/dl) were measured using commercially available enzymatic reagents adopted to an auto-analyzer system. | baseline, wk 12 |
