Rest day nutrition

I've seen it quite a few times where competitors adjust calories on a rest day, typically bumping up fats and decreasing carbs, with protein remaining the same.

However, after listening to Broderick Chavez on a couple Revive Stronger podcasts, he strongly refutes the idea of doing this and even goes as far to say it's detrimental to the overall picture.

So a few questions to those who practice this approach.

First off, what is your reasoning for setting up your macros differently on a rest day?

How would you refute what Broderick has to say?

Thanks.
