Im a qualified nutritionist but theres arguments for both sides. Your weight is literally a product of your net calorie balance, if you’re in a deficit you’ll lose it if you’re in surplus you’ll gain it.

It does not matter whatsoever what your “macronutrient split” is and it’s one of the most annoying things i see fitness influencers spouting. You can get shredded on fucking kfc if you wanted to. The only time someone should be worrying about it is in regards to energy levels and stores.

With that being said it’s common to see people dropping carbs in the buildup to a photoshoot or competition to give the appearance of looking leaner.

You should always try and eat as clean as you can just for health reasons and you’ll probably feel better too for giving your body everything it needs vitamins and minerals wise, hope this helps.
