CICO has not been debunked at all. If you take it to the extremes like eating 30k cals in a day yes your body will pass much of it undigested, but that doesn’t debunk it at all but rather adjust one of the 2 inputs into the equation, and for the vast vast majority of people following anything resembling a sane diet, CICO is the determinant of weight loss. You can eat straight sugar in a caloric deficit and body weight will fall off of you. You can eat straight fat or protein and it’ll do the same. You can eat in one meal or 20 meals. It still holds in every single study ever done.
