2. I know plenty of successful natural bodybuilders. Look at Eric Helms, Alberto Nunez, Layne Norton, Jeff Alberts, Matt Ogus, Milone. All of these actually know about nutritional and training science. But, that really means nothing. If the biggest, most jacked guy in bodybuilding told you olive oil is the best source of protein, would that make it true just because he said it? That's the basis of your argument. Logical fallacy.
