I had a mostly vegetarian diet for 4 years. Very hard to get enough proteins to build muscle. Hard to lose fat without losing muscle. I'm not saying it's impossible as there are vegan athletes proving it, but I found it significantly harder. Your best bet is something like soylent or supplement. After a very stressful period I started experiencing stomach problems, immune system problems, lack of sleep, depression. I tried changing a bit of everything and moving my diet to meat, eggs and vegetable made a huge difference; while I think it was mainly stress related, somehow a more varied diet helped me. In the end I think it's better to worry about finding your balance more than following some ready made recipe.
