PS — the malt o meal with turkey gravy won’t increase the BUN much as it’s lower protein but it is decreasing the protein of the overall diet and KD diets are already very low in protein. The kidneys need adequate protein to be able to filter properly (referred to as GFR).

Here’s a little blurb about it if interested
“In 1923, Addis and Drury [45] were among the first to observe a relationship between level of dietary protein and rates of urea excretion. Soon after, it was established that increased protein intake elevated rates of creatinine and urea excretion in the dog model [46]. The common mechanism underlying increased excretion rates was eventually attributed to changes in GFR [47,48] and Van Slyke et al. [49] demonstrated that renal blood flow was the basis for GFR mediated changes in clearance rates in response to increased protein intake” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1262767/

Protein INCREASES excretion of urea (also referred to as BUN) and creatinine by helping move them through the kidneys more efficiently.
