serrelind, protein is converted to glucose to support glucose homeostatsis as needed - if it's not needed it's not converted.

Excess protein, protein that doesn't go toward repairing or buiding new tissue would be use for energy or wasted. Fat storage cannot happen without insulin present. With no insulin present excess protein is literally unused.

What happens if you eat a lot of protein? Metabolic starvation - if you don't eat much of anything else with it.

Now, the real question is how much protein do you think it takes before you get to excess protein?
