> 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".
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.
