    Protein is vital and is available on any kind of diet. Many vegetables, all meats, all fungi

    Humans can either live on carbs or live on fats, in both cases we must also eat protein

    Humans cannot (though cats can) live on protein, look up rabbit starvation. You will starve if you eat only protein, where eating only fat or only glucose will kill you much more slowly with vitamin deficiencies
