I've been a vegetarian my whole life (16 years) and I'm 5'11 148lbs.
And as far as Pandas dieing to crappy nutrition due to them being "vegetarians", i found some info on Wikipedia to address that:
Two of the panda's most distinctive features, its large size and its round face, are adaptations to its bamboo diet. Panda researcher Russell Ciochon observed that: "[much] like the vegetarian gorilla, the low body surface area to body volume [of the giant panda] is indicative of a lower metabolic rate. This lower metabolic rate and a more sedentary lifestyle allow the giant panda to subsist on nutrient poor resources such as bamboo.
The reason they have a shitty diet is not because they are herbivores, its because they exclusively eat Bamboo.
Humans on the other hand consume many other things that contain all the nutrients they need. You don't need for Protein, nuts do the same job.
lul, Vegetarians eat nuts
Anyway, being a Vegetarian is in no way has a negative effect on someone's nutrition consumption, weight, or w/e.
Plus being a Vegetarian lends itself to a lot of small-talk which can be used on the ladiez :)
