The effects of a high protein diet on indices of health and body composition – a crossover trial in resistance-trained men

Table 5 Case reports - renal function on two subjects with the highest protein intakes

	Baseline	Normal protein	High protein	Reference range
Subject 1
PRO intake g/kg/d	3.98	4.18	6.59	724 % > than the RDA
BUN mg/dL	25	34	14	7–25
Creatinine mg/dL	1.26	1.09	0.96	0.60–1.35
eGFR ml/min/1.73 m2	88	105	122	§
BUN/Creatinine ratio	19.8	31.2	14.6	6–22
Subject 2
PRO intake g/kg/d	2.56	3.61	4.66	483 % > than the RDA
BUN mg/dL	22	26	20	7–25
Creatinine mg/dL	0.97	0.97	1.02	0.60–1.35
eGFR ml/min/1.73 m2	125	126	119	§
