Paleo has nothing against carbs, it simply restricts the sources.
I eat paleo as well and if you want to gain any mass, your going to have to start upping your carbs. Honestly, your picture looks like you're starving, and there is zero chance that your going to up your mass AND reduce your fat levels with a starting canvas like yours.
If you want to stay away from things like yams and quinoa, your going to have to turn to fruits.
I would suggest doing a lot more reading on this site before your next post, to gain insight into how mass (and I mean real mass) is gained, and then tailor your macros accordingly.
It also seems like you need to gain a better understanding of paleo. I would suggest starting with marksdailyapple.com
