Don't forget that your basal metabolic rate is not constant in different circumstances and over the duration of your life. It actually goes up if the calories consumed go up. I guess in some lucky individuals it may go up high enough to offset all extra calories - but, surely, to a certain limit.
Also, this BMR varies between different people - even if their bodies are very similar. So that is probably the source of the confusion "i know this guy who eats all the time and is skinny, therefore the calorie theory is wrong".
This page has links to numerous studies that prove the calorie in - calorie out theory. As far as I know, this theory was not yet disproved by any clinical study.

If we have evidence that something isn't true, and we even have theoretical reasons why it wouldn't be true, why continue calling it "confusion" when someone points out that it doesn't seem true?
(By the way, no one, anywhere, is disputing the laws of thermodynamics when they say that "calories in / calories out" isn't the whole story.)
Except you don't. A guy who eats all of the time and is skinny has a high metabolism. That's still 'calories in' < 'calories out'. The reason it's being called 'confusion' is because someone has made the mistake of thinking 'calories in' = 'weight'.

That's precisely what they are doing. Metabolism, poor calorie absorption, exercise, etc all fall under 'calories out'. It is the whole story, it just doesn't provide a lot of useful details about how to boost the 'calories out' category.
