The purpose of this retrospective study was to investigate the effect of dietary counseling on body mass index (BMI), serum albumin, and blood urea nitrogen (BUN) in pre-dialysis patients.

Medical records of male veterans with Stage 3–5 chronic kidney disease were examined until four hundred patients who met study criteria were identified and entered into the study: 200 who had received nutrition counseling and 200 who did not.

Results of two-tailed independent t-tests showed no significant differences in BMI, serum albumin, or BUN in subjects who received nutrition counseling versus those who received no nutrition counseling. In subjects who received low protein diet counseling versus those who did not receive low protein diet counseling, results of 3-way ANOVA indicated no significant differences in BUN or serum albumin levels.
