I also feel I am not getting enough protein on a vegan diet. I have been vegan for six years and really struggle to gain muscle mass and any muscle I build seems to fade quickly. I did experiment with some wild salmon for a few weeks to see if it would make any difference. It absolutely did and now I am trying to figure out why I am not utilizing the vegan protein in my diet. I am gluten intolerant so I can't do wheat but I do eat: tofu, tempeh, nuts, seeds, beans, lentils, protein powder (daily), quinoa, chia, etc. The one thing I think I could do more of is tofu and tempeh. Any suggestions is appreciated. I hate the idea of going back to animal flesh and will do whatever it takes to avoid that path. Help!
