Bullshit, I say!
There are plenty of cheap foods for bulking, including:
Watch for deals at the supermarket too. I just bought some 20 oz loaves of wheat bread from the store today for a buck a piece. Thats about 2000 calories per dollar. Anytime you can get meat cheap, like 2 for 1 specials, etc, jump at it.
Of the above list, I especially like canned fish, but there is the mercury concern, so consumption should be limited. If it weren't for the mercury, I'd eat canned salmon by the case.
And, to, answer your original question, ramen = no good.
