Why isn’t a 100% protein food possible.

I’m sure most nutrition-conscious people are aware of the 1g protein/10 calorie ratio for determining whether a food is high protein. To my knowledge the highest protein foods & supplements out there have a 2/10 ratio, but theoretically shouldn’t a 2.5/10 be possible, since 1g of protein generally contains 4 calories (I am aware this is a rounded up figure that can vary, but that only furthers my inquiry). What is the scientific reason for this? Is it impossible for a molecule to fully consist of proteins, so the remaining 2ish calories have to consist of other macronutrients, or is it something else?

Protein poisoning is when the body takes in too much protein with not enough fat and carbohydrate for a long period of time. Other names for this are “rabbit starvation” or “mal de caribou.” These terms came about to describe only consuming very lean proteins, such as rabbit, without consuming other nutrients.
