Whole food protein is the hardest food to digest. It takes more energy to digest and it takes the body longer to digest protein than fat and carbs.

When cutting it is advisable to eat whole protein rather than either liquid protein or carbs. This is because if the satiating and themic effects.

I just can't imagine eating 500g protein every day, even if half was liquid or whey. At what point would the body have a break from digesting food. I actually don't think it would be healthy. That's not a criticism btw, just my view.
