Why do most vegatarians look like they are starving? 
Not the good kind of skinny the most of us wish we could get back to, but the kind if skinny the makes you wonder if they'll survive the impact with the wall that occurs whenever they walk in front of a fan. 
Well, as the pic below shows, I'm not Ahhnuld, but I am not going to blow away anytime soon. vegetarian for many years now. Down from 210 last January to about 185 now, this was taken in August. That's an 8-pound maul I'm using and I've been swinging it all day.
Something to think about:
Herbivores are generally big and strong animals and tend to have great endurance for long-range travel: Elephants, cattle (think Brahma bulls), horses, hippopatimus, giraffe, rhinoceros, elk, moose, all the breeds of deer, water buffalo, regular buffalo, the list goes on.
Carnivorous animals are some of the fastest, (necessry to run down prey) but
generally give something up in size and stamina: A cheetah gets one or two tries to bring down a meal, then it's done, same for lioness, jaguar, all the big cats. Cats are obligate carnivores, though, their bodies need meat for the amino acids, etc., that they can't get by plant-based diet alone. Exceptions being the larger predators such as bears (omnivorous), sharks, whales, etc., and the larger primates.
The animal kingdom (of which we are members) is pretty well represented by both factions.
