I think,its b/c cortisol (being stress hormone) triggers breaks down of protein(property of cortisol to mobilise AAs from muscle tissue)into aa,which being used by liver(metabolised) an dwill produce urea(eXCESS NITOGEN EXCRETED).

cortisol has catabolic action on the protein ,so eventually the nitrogent will be released free and finally excreted by kidney

That sounds reasonable. So this is why cortisol cause a negative nitrogen balance. Hmmm.

Because negative nitrogen balance occurs when the excretion of nitrogen exceeds the daily intake and is often seen when muscle is being lost.

does thyroxine not have the same effect on the tissues. does it not increase bmr by enhancing gluconeogenesis by utilizing amino acids.
I remember a usmle question where both were mentioned as answer choices. What should have been the best answer and why?

well, if thyroxine stimulate gluconeogenesis, then those nitrogen will be used, so the quantity will decrease, but it will not cause nitrogen loss.
