Subject: Do you have to consume a pound of food to gain a pound?

Is the amount of food you eat directly related to how much weight it is 
possible to gain? what I mean is, in order to gain a pound of weight, do I 
have to eat a pound of food? this doesn't seem likely, as some highly caloric 
foods are very light weight - like whip cream! I would appreciate any helpful 
info regarding this matter. :)
