I eat over 5000 cals a day, everyday. I'm a powerlifter so my diet will not get you what your looking for. Diets are highly individualized so you have to experiment and do what works for your body. Just a few years ago, I had always considered myself a hardgainer and my mind was set that I could never be big. I had hovered between 165-180 most of my adult life. I looked in magazines and online at certain eating plans and followed them with very little success. Then I figured out how to eat for my own body. 2500-3000 calories a day didn't work for me. What others are doing may not work for me, or you, or anyone else. YOU have to educate yourself on what to eat and when to eat it so it works for your own personal goals. I would suggest reading a couple books: "Nutrient Timing" is excellent (and available at books stores). Some of the guys I train have made dramatic improvements just by following the basic principles in that book. It covers diet and supplementation. "Power Eating" is another I find interesting (you can find it on elitefts.com). This one, however, may not be applicable to your goals - yet.
