Yeah, what they all said!
I started out at the beginning of this year at 5' 10" and 130 lbs. I am now at an even 160 and still gaining. I take in around 4000 calories a day. A typical day for me is around 500g of carbs too. Your 2150 calories is barely a maintenance level, if that.
if you're a true ecto like me.. you might have to do a little bit of a dirty bulk.
Word. My dirty bulk treat is milk, lots of milk! I drink a gallon a day. I have gained a little body fat since I started drinking that much, but you can't tell on me. I had very little to begin with.
The mainstays of my diet are milk, yogurt, liquid egg whites, whole wheat anything/everything, beef and chicken (more beef than chicken), potatoes, quinoa, couscous, broccoli, green beans. I do not take any whey powder except on workout days. Then I have a gainer shake at work, and I use whey in my post workout shake. Otherwise, I hit 4000 calories without using any supplements. It's a lot of food, and granted the milk helps me reach that calorie number, but it is still a lot of food. But that is what it has taken me to gain the 30 lbs in 5 months.
If you want, send me a PM with your email address and I will send you a couple of my meal plans I have saved in Microsoft Excel.
