Banana's are bad for low carb!!

Although I like a good banana every now and often, they are off limits for low carbs they are extremely high in carbs.
Has anyone every tried the kale green shake?
It called for banana's I purchased some of the ingredients, and I still may try it out, but not for the next few days or so.
It has kale, frozen fruit, banana and ice base and some recipes call for almond milk. As the added liquid portion has anyone tried this recipe?
Thanks-jbug

I have had the 'green shake'  with protein powder, kale, mixed frozen fruit and almond milk.  I thought it was good.  I've made similar with spinach too.  And it's really healthy!  I also use Torini low sugar syrup sometimes for flavoring if needed.
