There`s plenty of professional athletes who are vegan, David Haye(boxer),Nate Diaz(UFC) and a few record holding powerlifters I know. As long as you`re getting your required macros(protein/carbs and fats) you`ll be fine. Too much red meat has a high saturated fat content, too much bacon has too high a level of sodium etc,etc. You can eat anything in moderation.
