I've been eating along paleo lines for about 6 months now and since I 
find myself sticking to certain eating patterns so I thought I'd see if 
anyone on the list thinks I'm eating too much/too little of anything.

I'm 23 yrs old and have always been very lean.  I've dropped about 10 
pounds to 175 (I'm 6'0) since going paleo but haven't noticed much 
change in body composition.  Living a student life with a tight budget 
my meals are very plain and repetitive.  Most of my paleo interest came 
from following Art De Vany's blog which I think is the best advice out 
there.  Every fourth or fifth day I eat sparingly, sometimes not 
anything.  My goals are to maximize muscle, minimize fat and keep my 
weight up.

Have been eating about 3-4 meals a day that each basically consist of:
- 1 portion of meat (grain-fed) or seafood (cold-water) or omega-3 
enriched eggs
- 1-2 handfuls of mixed tree nuts
- 1 piece of fruit (mainly berries,apples,oranges)
- at least 1 serving of dark green and other vegetables
- 1 tbsp of olive oil or udo's oil

I usually eat canned seafood once every other day and same with eggs.  
The meat is cheap fatter cuts such as ground beef, pork chops, chicken 
wings, sausage.  I do buy some grass-fed beef pemmican from U.S. 
Grassland Beef but I can't afford much of it (wish I knew of somewhere 
in Canada I could get pemmican).  I'm concerned about eating too much of 
the wrong fats in the long run.  The udo's oil does help to balance my 
o-3 to o-6 and I also take a few fish oil caps daily.  Other than that 
the only other supplement I take is 1000IU Vitamin D a few times a week 
in the winter.  Need to keep my calories up because I train with weights 
and play quite a bit of sports weekly, so I'm relying on eating high 
fat, might not be getting enough carbohydrates since I rarely if ever 
eat root vegetables and stay strictly paleo.

Also any suggestions for getting some more calories in there at meals or 
supplements I should consider ?
