<P> Excess protein is sometimes cited as the cause of this issue; when meat and fat are consumed in the correct ratio, such as that found in pemmican (which is 50% fat by volume), the diet is considered nutritionally complete and can support humans for months or more . Other stressors, such as severe cold or a dry environment, may intensify symptoms or decrease time to onset . Symptoms include diarrhea, headache, fatigue, low blood pressure, slow heart rate, and a vague discomfort and hunger (very similar to a food craving) that can be satisfied only by the consumption of fat . </P> <P> Protein poisoning was first noted as a consequence of eating rabbit meat exclusively, hence the term, "rabbit starvation". Rabbit meat is very lean; commercial rabbit meat has 50--100 g dissectable fat per 2 kg (live weight). Based on a carcass yield of 60%, rabbit meat is around 8.3% fat while beef and pork are 32% fat and lamb 28% . </P> <P> Given the lack of scientific data on the effects of high - protein diets, the US Food and Nutrition Board does not set a tolerable upper intake level nor upper acceptable macronutrient distribution range for protein . </P> <P> In U.S. Military Arctic Light Infantry Training (ALIT), it is taught that rabbit takes more vitamins to digest than it returns . It is recommended in survival situations to refrain from eating at all if rabbit is the only thing to eat . Though, instead of eating the meat (which consume your fat and vitamins), you could simply boil the rabbit meat to extract the fat and some minerals and vitamins (some vitamins will be destroyed by temperature). </P>

If you eat just rabbit you will die
