On the whole it is much better to eat whole fruit and vegetables than to juice because they contain fibre as well as lower amounts of sugar. Some of the natural goodness may be lost in juicing too, as some vitamins deteriorate quickly once exposed to air, light or knife damage.
However during the treatment it may be easier for you to include your fruit and vegetables as a juice or as a smoothie. If you can just try to consume your juice soon after preparation.
If you are trying to contain your weight you need to remember that juices are much higher in calories than whole vegetables or fruit which can be a problem if you over consume.
