Yeah, hence why this is an oversimplification, not false. Yes weight loss/gain is by definition the difference between calories in vs calories out, yet this simple definition makes it seem like losing weight should be as simple as a) reducing calories in, or b) increasing calories out, when in actuality reducing calories in may reduce calories out by the same or even greater amounts. It turns out these two variables are not independent, but instead connected by an extremely complex network of factors. So yes, for many people, framing weight-loss as calories in vs calories out is a dramatic oversimplification.
