here are a few things that are of concern -
1. You seem like an ectomorph, at 6 feet and 145 lbs, so if I was you, I would eat non-stop, lets of good fats, tons of carbs.
2. Set realistic goals. For you to be 200lbs, you have to put on 5lbs of mass, that will likely take more than a year of training. Maybe break it down into smaller chunks, put on 3-5 lbs this month etc. etc.
3. Some of your number seem a little off, which website source are you getting them? 2 sausage for 33g of protein? thats a little high, unless the sausages are really big. (I don't know, arent sausages long thin peices of pork?) How did you get some carbs in your meal #3, most tuna is pure protein, very little carbs.
Water has no carbs either.
4. Sausage and biscuits seems to be your staple meal...... I would change it to some form of beef and rice/chicken and rice. Rice can be your primary source of carbs, I don't know about biscuits? (What are biscuits?)
5. Ice Cream???? Before a workout, the sugar alone will give you an insulin spike that you will sufer a huge crash during your workout. Should replace Icecream with things liek brown bread, half a potato, rice, pasta even. Yogurt? that may be abetter alternative.
6. You got 74 g of protein out of a shake and icecream? How many scoops you have in there? Thats a lot of protein to be taking in for one meal, especially before a workout. Per meal, keep protein between 40 - 50g, it is very likely that if you ahve more than that, you body will not get a chance to utilize it whatsoever.
7. Egg whites give you about 4 - 6 g of protein, depending on the size of egg. Since you probably are an ecto, you can eat the yellows as well, just spare some.
8. Read h19 link to glycemic Index of carbs, and when to eat which. There is a sticky by YJ on bulking diet as well, and protein breakdown, might want to give that a look.
You seem like you have a good idea of how much protein carbs etc you should be eating, but i think the sources are conflicting.
keep plugging at it bro, every little thing counts.
Pay close attention to your nutrition pre and post workout, thats important, and there is a thread on that as well.
