The idea of a "debate" around CICO is pretty ridiculous, in the sense that the role that thermodynamics plays in metabolism is well-established and agreed on by everyone
What we're actually seeing is a shift in emphasis away from calories in and more towards calories out

What I mean by this is that more and more nutritionists seems to be recognizing the error in the initial premise of the amount of calories eaten being the only significant factor in weight gain/loss
This is obvious in cases like hypothyroidism, etc, where metabolism is impaired

This isn't a new idea or mutually exclusive with CICO, just a shift in emphasis from one side of the equation to the other
I think most everyone would agree that the amount of food you eat matters, but also that lack of exercise, hormone imbalance, etc, can impair weight loss

A lot of this also has to do with diet politics, such as using an exception to CICO as justification for certain diets like keto, veganism, etc
At the end of the day though I have yet to find a single study showing weight loss in a caloric surplus from any of these diets

This study is an excellent example of this, it found that a ketogenic diet did not show increased weight loss over a high carb diet when the two groups were matched for calories and tracked for 12-months

This is not to say that these diet don't work, but that when calories are matched the advantage they offer is being easier for some to follow
It's well-known that many of the foods in vegan or keto diets are highly satiating, so they make it easier to maintain a caloric deficit

Then even minor initial weight loss can improve hormone balance as a whole, since visceral fat is burned preferentially
This can improve things like insulin resistance via reduction in fat around the pancreas which impairs its function, other organs likely see similar effects

You don't need to follow any particular diet to achieve weight loss, but you can experiment and find what works for you
The basic principles of increase metabolism via balancing hormones, sun exposure, and exercise, and focusing on satiating whole foods, are the most crucial
