I agree with both Windex and GH. I have no idea how your getting to 6000cals a day with just chicken, egg whites and rice. It appears that diet is something you would find as a diet "guide", that is meant to be tweaked to your body and situation but has yet to be tweaked.
I know you said - "I'm happy to discuss my training/diet and bulking / cutting phases but that wasn't really the point of my thread" - that discussing your diet wasn't the point of your thread but, correct me if I'm wrong, your trying very hard to reach a goal you have set for yourself. Gear alone is not going to achieve that goal for you, diet is the most important part of the equation. If I were in your shoes I would be jumping for joy that some of the more knowledgeable members here are willing to help you with your diet to achieve your goal. Remember, just because your trainer/coach said something doesn't make it necessarily right. I would gather information from multiple sources and then make up your mind from there. I remember a couple threads ago we were talking about training and several members said their first coach trained them to go to failure on every set and they trained that way for years and years until reading and learning for themselves and coming on to boards like these. When they switched their training around they made tremendous gains. Just some, excuse the pun, food for thought!
