What Frank Zane had to say about Arnold's eating habits. Taken from the November 2011 issue of Muscle & Fitness...
"Arnold knew how to diet but didn't always have the resolve to do it. That was his downfall. I was eating breakfast with him at Denny's one time, and he said, 'Frank, it doesn't matter what you eat, as long as you eat a lot of it.' And then he had a whole bunch of hash browns, eggs, pankcakes, and toast. When I beat him, he look like a smooth, white whale."
