i’m not sugggesting you do that. That’s not a good diet for anyone.
It really would be helpful to know more specifically what it is that you ‘want/like to eat’. To figure out if protein reduction makes sense, I’d need to know more. Like, are you eating a lot of junk food high in carbs? A lot of processed foods? Eating whatever you want means different things to different people. I’ve heard people say this before, and it turns out that means just enormous amounts of meat to them.
I think if you’re eating a diet high in sugar and processed carbs, the simple answer is to eliminate those completely, or close to it if you can, and leave the protein shakes in. If you’re eating… more than 200g protein per day of meat/whole foods, then the shakes may indeed be what should go.
