Question Why low Bicarb in DKA?

For some reason I always getting this concept wrong and rather than memorize I prefer to understand.

I just did a Uworld question which described a male approx 23 yrs old who had polydipsia and polyuria and whose breath had a fruity odor. Okay...so he had diabetes Type 1- diabetic ketoacidosis.

Now from that I know that his Ph will be decreased and his H+ will be increased. His CO2 will also be decreased because of his Kassumal's breathing.
My question is why is HCO3 decreased?
