I need a little tweaking on my diet. I'm hoping you guys can help me out. I have a lot of questions so I'll start with my stats

I'm on about week 10 of a bulking diet. Started at approx 167lbs. 2 weeks ago I was at 176 and as of yesterday I was able to drop back to about 173 (5'11").

I have an office job so sit on my ass most of the day

Workout routine is as follows:
Mon - chest, bi's/1hr, followed by 15min elipticle/vigorous
Tues - Legs, forearms/1hr
Wed - off
Thurs - Back, Tri's/1hr, followed by 15 min treadmill/vigorous
Fri - Shoulders/dips/pullups, followed by 15 min elipticle/vigorous
Sat/Sun - 1 day off 1 day 4 mile run

Diet:
Meal 1
Protein/fat
Egg beater omelette, 1/4c ground beef, spinach, 1/4c fat free cheese
400cal, 2g carb, 40g protein

Meal 2

approx 250-300 cal, 30g carb, 20g protein

Meal 3

550cal, 54g carb, 65g protein,

Meal 4 -pre workout

300cal, 25g carb, 10g protein

Meal 5 - post workout
Protein/fat
2 scoops protein shake w/1%milk and banana
1/2 chicken breast
550cal, 25g carb, 70g protein

Meal 6
1/2c ground beef
? 150cal, 20g protein?

Meal 7
Steak, Tuna, or Turkey 12oz serving, 1/2c brown rice, vegetable, 8oz milk
approx 500-700cal, 40-60g carb, 40-60g protein

If you do the math, it does not add up to the amount of calories I need for the day. I can sometimes squeeze in another can of tuna but I am beyond full all day. About 2 weeks ago I cut my carb intake in half. I was feeling tired all day and watching my belly grow faster than my strength. The lower carb diet is helping a lot but I can't seem to eat anymore. Based on my stats I burn about 2900 cals a day so I need to maintain at least 3500 to gain 1 lb per week.

Any ideas on how to up my calories without all the carbs. Please keep in mind I cannot force anymore food down, I will need to try and supplement meals with higher calorie intake. My goal is to get 8 meals at 500cal a piece.

If you made it all the way through this long thread and can offer advice, then thanks in advance.

I must also add my concern for the amount of cholesterol I'm taking in. Any of you vets have words of advice for the potential clogged arteries?
