Great feedback @garethnelsonuk :)
I also agree this is not a long term solution, this is an intermittent fast and not something i would ever recommend as a full time diet option. That's the reason for the abundance of Romaine in my juices, they are amazing and very under used. Romaine lettuce’s calories are 20 percent protein. Like all whole foods, much of this protein is complete, but the amount can be increased by combining with balancing proteins. They also contain oega 3 and 6 and are alakaline forming. Sure not much of them is fat but simply no reason not to include them.

However i would encourage people to replace a meal with a juice as an ongoing thing. As you say above the nutrition hit from just one of these is simply hard to beat.
