Sorry, but this protein scam is getting tiring. I personally do sports 6 days a week, couple of hours daily on pure vegan diet. I've been doing this for 6 years. I'm just one in a million who does the same. There are vegan bodybuilders, Olympic athletes, ultra-marathon runners etc.
Let me show you an example. Everyone thinks the meat-alternatives are not full of nutrients and you will miss something if you don't eat dead flesh. That's just utter bollocks:

I've tried and Beyond burger tastes out of world. It's basically the same thing as meat without the disgusting chewy parts that would remind you that you are actually eating a living being which was killed for the pure selfish purpose of satisfying the taste buds of people.
I think this image (see link for the actual research) sums it up pretty well. The plant based alternatives are a hundred times better for the environment (no need to further destroy rain forests), and they are better for you. Less chance for cancer and heart-diseases.
What's not to like about it?
