How big was Grok?
I have a lot of curiosities about diet and nutrition as it's part of what I'm studying and its quite controversial for me to consider recommending this diet to people considering it is not taught as a healthy diet. I have yet to engage in a discussion with my peers on the subject as I don't feel I know enough yet.
May be a stupid question but how sure are we that Grok as you call him, was actually big and muscular? How can we know that just from bone fossils? For all we know Grok could have been a fatty? I naturally have trouble putting on weight so I cant really say going Primal has helped me with reduced fat mass.
