The almond milk could definitly keep your hunger up; you couldn't make it weak enough! HOWEVER, when I did a 40 day fast, I sometime supplemented with soya milk (which would have the same hunger-inducing properties, because of its fat content, etc) -- and I really didn't find it unbearable. Also, a juice fast isn't as hunger-inducing -- for me -- as a water fast, so on the whole...
However, are you making this almond milk yourself? You need to be especially careful when on a fast not to be taking in any preservatives, etc etc.
Hemp powder should be fine. I also supplement with Kelp (for iron) and wheatgrass; this you can either juice yourself or use the powder. More important than "calorie content" is making sure you're getting enough vitamins and minerals.
I don't know about zylitol (sp?!) but honey is actually an excellent natural product; super fast absorbtion and (in moderation) perfectly fine during your fast. It has great properties and I'd recommend that as a sweetner.
Hope that helps!
