not gain fat in a negative energy enviroment?'. Your body would have no use for all the calories coming from junk like oreos (just my prime example), so that is going to get stored as fat.
Again, I propose the idea to you: Go ahead and eat a few hundred under your maintenance level (if you can determine it), allowing all caloric intake to come from oreos.
If all the foods you ate were of whole, rich, nutritious sources, then maybe a negative energy enviroment wouldn't lead to fat gain. However, when your body has no use for all the junk you throw in it, some of it is going to be stored, regardless of the caloric intake or expenditure on a whole.
