I started using one. I am trying to lose my last 10 pounds (stubborn lower stomach fat!) to get to lean, mean boxing lookin machine. I eat way too much junk food so decided for the rest of March, and all of April my diet is going to be juice in the morning, a meal in the afternoon, and juice at night.
Juice I am drinking right now as I type is a kale, spinach, apple, ginger, carrot combo. Pretty good. Don't taste like coca cola, but it's delicious compared to what I imagined it was going to taste like.
Some pics I took...
Why you ask?
