Excess Protein in Diet /Protein Poisoning

Met an interesting person today,perhaps a case.
Rabbit starvation.
Low blood pressure, diarrhea, headache, tiredness,slower heart rate than normal,food craving that  can be satisfied only by the eating
fat.
It is also know as protein poisoning,a rare form of acute malnutrition caused by a near complete absence of fat in the diet.

Meat and fat should be consumed in the correct ratio. Excess in one and complete absence of the other groups for prolong period doesn't serve us well.
