ok...a simple, possibly dumb question.

most of u know i used to be pretty fat (5'10" 220lbs, 38" waist). then i went on a mad cardio and weightlifting spree, and i got down to 150lbs/30" waist a year ago.

after i achieved my weight loss goal, i cut back on cardio and focused more on weight lifting. now i'm happy with what i can lift, but i wanna get SWOL. im getting stronger, but i'm not gaining mass.

what do u recommend for the bulking process? should i just eat as much as i can, avoiding junkfood? i guess i'm paranoid that all the food will go to my midsection. also, i'd prefer to do it all natural, no supplements.

or maybe i just cant get way, because of genetics and stuff?
