also by dense calories keep in mind too like say a strawberry smoothie 64 ounces while dang tasty it might not be enough calories to keep on going from one meal to the next. So i typically wont rely on something like that for a meal. But I might make one that is heavy on berries but also has a ton of bananas or dates as well. Or drink it while eating some other denser meal.
Or in a pinch spike it with a pile of white sugar..... :
