I don't think adding in a oral would be pointless if you are one keto. Add in any oral you want. Make sure your salting your food that will help you feel a little more full. One of the aspects that goes with keto is that the flatness that you have now will be supercomensated once you add carbs back in. Once you start eating carbs again your body will absorb them so well and your pumps will be insane.
