This is something I've said repeatedly in other places and this is a certain segment of people who can't understand it. CICO is, especially at the population level, terrible dieting advice. We have decades of experience and oodles of research showing that, as advice it does not work. However, it is, as you point out, basically tautologically true/correct. For CICO to _not_ be correct would essentially be breaking physics and generating mass/energy from nothing. Yes, your body can change it's energy expenditure in response to dieting, but this is accounted for in the CO part of CICO. If you consume fewer calories than your body expends (in all the myriad of ways that your body can/does expend calories), then you _must_ lose weight. The fact that CICO is true does not make it good advice but the fact that it's bad advice doesn't make it false.

I think of it this way: CICO is an axiom we have to assume in order to figure out why a diet isn't working. E.g. if your input is 1200 calories and you work out, but you aren't losing weight? Maybe your NEAT is way down (or you have a thyroid issue). You are super active but can't lose weight? Maybe you aren't tracking food calories accurately, or you need to eat more satiating foods. CICO isn't a strategy, it's part of the landscape and your diet is a strategy to navigate that landscape. But no matter what your particular strategy, it is always going to involve eating less hyper-pallitable foods and getting more activity. That may not be all, but you cannot go from obesity to a healthy weight without those things.

CICO makes me pay attention. Pay attention to what I eat and how often I exercise. I rarely actually count, but I do lower calories when I look at a label and say OMG. Like, who knew a shake was 2000 calories? Hmm, fries only 500. I just switch and cut my calories by 1500. I’m so good, I deserve these fries! Yum.
