Except that the human body is way more complicated than that. Whenever you try to increase calories out by exercise, your body just finds somewhere else it can economize, because it wants to operate on a fixed budget. This can include pulling calories from your immune system, or making you subconsciously move less throughout the day, or even sleep more. You can only overcome this for a limited time. Kurzgesagt has a good video on this phenomenon. What you actually want to do is reduce calorie intake.
Exercise is good for lots of reasons, but it isn’t a good way of losing weight long term.

Is that not the exact sentiment when people bring up CICO, though?
Not really. Lots of people talk about excecising more when it comes to loosing weight, and many of those follow CICO. Not realising that isn’t how a human body works with regards to excercise. You also see people claiming that genetics are not signficant, or that slow and fast metabolisms don’t exist. Even though we know all of these things are a factor. It’s mental what some people believe about diet, nutrition, and excercise. Likewise everyone using BMI pretty much is an idiot, even in school I was told that isn’t a good metric otherwise every athelete or body builder would be obese.
Also still not convinced CICO is even a thing. Digestion is not a 100% efficient process. Calories are measured by burning something, and human metabolism isn’t a fire.

So… you don’t even agree with the crux of your own argument?
Maybe I’m misinterpreting CICO, as I assumed it could be taken as just it’s initialism without having to be associated with any more complex fad diet.
I understand that when people reference something, interpretation is not universal. There’s always going to be variance. I just hadn’t had that experience.
I also know it’s a very hard metric to track. It will vary depending on body type, metabolism, and even psychology. I don’t recall that being disputed, though. Just that, at it’s core, it’s more about reducing caloric intake than increasing caloric use.
That doesn’t discredit calories in calories out? They didn’t even mention exercise or imply that you didn’t need to reduce your food intake. It works. When I am on a cut I can estimate down to within a few days how long it will take me to get where I want to be just following CICO.
Reducing Calorie Intake is only the first half of CICO. Not everyone can even absorb the same amount of calories from the same piece of food, because calories are about burning stuff not about human digestion and metabolism.
