I did a lot of juicing when I was having cancer treatment. I found it really helpful but also a lot of work. So here are my comments:

* fasting generally is known to produce beneficial changes to your health, but this includes more "integrated" forms of calorie restriction, like intermittant fasting & limiting the hours in the day in which you eat.
* you can get fast-like results to your blood profile by reducing only carbs on fasting days
* the most beneficial veggies to juice are the green leafy ones, but they taste really bitter & strong when juiced. I countered this by adding more of the sweeter juices (beet, carrot, apple etc) but that increases the sugar load. I was only having small portions, but if juices were your main thing you'd need to be careful with this.
* prep & cleanup - you need to get a veggie washing/chopping system going, as well as a handy composting/cleanup system. You need LOTS of veg to get a decent amount of juice & it takes work. Also, storage space
* You need to drink the juice soon after you make it or the enzymes start breaking down the nutrients. That means you need to repeat the routine several times a day.
* don't buy the juicing carrots. They are old & nasty

Good luck with it, let us know how you get on.
