You have to consider goals and allotted nutrients as well. If you’re looking to gain muscle and have a reasonably good ability at keeping bodyfat low, then fruit sugar smoothies are not gonna kill you.
I personally wouldnt do it, but it’s not gonna matter much in practice if your total carbs protein fats and calories fall into place with what you’re trying to achieve.

I mean, how much fruit juice are we talking about here? And what are your goals at the moment?
