I honestly don't measure! I do try to consider adding approximately equal servings of veggies and fruit. yogurt and juice or any liquid to thin if needed. I have also added some seeds like flax or chia. There a lot of recipes on the net and cookbooks for the exact measurements.

I don't measure anything! I splurged for a Vitamixer years ago so I have a good size container to mix things in. I add one carrot and a stalk of celery for sure. Usually I add a handful of greens (spinach, Kale,etc) and any fruit I have on hand, almost always blueberries . the blueberries and greens make a muddy looking green, but I don't mind the taste. I ust noticed your post, sorry it took so long to respond.
