Meet Hugo and Ross Turner, identical twins. Being made up of identical genes, these two men know that they are special. They are using their special-ness for science. Ross and Hugo noticed the rapidly growing change of athletes switching to an all vegan diet. These athletes all claiming that the diet improves their performance. So the Turner twins decided to take out any possible bias and put the diet to the test. One twin was to switch to a vegan diet, and the other would stay on an omnivorous diet, all while they were both going through the exact same fitness program.
