So I'm about 6,0-6,1 135 pounds. I go to the gym 3 days out of the week, Mon-Wed-Fri

I know how to lift, I got my workout routine down. I've hit a plateau though, and i've been stuck on this plateau for a year

I just don't know how to eat properly. I have an incredibly fast metabolism. I'm also an undergraduate student, and the food at my university is expensive for a small amount, its ridiculous.

Along with all this, I love eating my veggies. Broccoli, Cauliflower, bell peppers, etc. I like having a salad every meal, or at least in two meals out of the day.

With that being said, I'm having an incredibly difficult time meeting my caloric needs to gain mass. Going primal, that need becomes even harder to meet.

I'm what you would consider an "ectomorph."

Do you guys think I need to step outside of the primal diet to gain mass?
