All this really depends on what you want calories in/calories out to mean.
If you want it to mean "eat more, get heavier," then fine. If that is the case, the whole concept is completely meaningless.
What I have seen across many "expert" diet sites is attempts to quantify weight vs activity and calories in a very simplistic way, and use those numbers for everyone. For example- a lb is X amount of calories, and exercise is X amount of calories per unit time, add the food calories in, and that is all you need to know. If you consider that calories in/calories out, it simply does not work.
It would be like if gravity were different for every single person, and people jump off a building and hit the ground at different times. Then someone comes in and says "what goes up must come down-that is all you need to know." yeah, but big frickin deal! Why does everyone hit the ground at a different time?
