On the subject of listening to research...make sure you know your sources. Of course protein factory is going to explain the benefits of whey protein--they sell the stuff. It is fairly easy to get a study to say what you want, especially when it is difficult to conduct truly controlled experiments on HUMANS. It is interesting--everyone who sells protein manages to find studies that suggest you eat a ton of it, and that their particular type is the best.
By the same token, who says you need a ton of grains, and a pathetic amount of protein? The government, who is trying to boost the agricultural industry. They claim that you don't need to eat a lot of protein to lose fat, just eat their farmer's fat-free grains. Most bodybuilders, however, who get to about as low bodyfat as is humanly possible, know better than that.
I think it is better to read these posts--these guys have tried different diets, supplements, etc, and know what has or has not worked for them. And most of them seem to notice that whey and other milk-based proteins are beneficial. But not becasue protein factory said so.
