I tried Isagenix.
Let me tell you that after doing Medifast 4 years ago (and losing 40 lbs) I would say that is a MUCH better route to go in terms of taste.
Granted, I went back to bad habits and gained everything back...BUT, Isagenix tastes HORRIBLE - AWFUL - DISGUSTING.
Do you notice I really say what I mean?
The shakes are terrible - the liquid you take for a whole day long (it's a fast liquid) is awful.
I'm sure it works - but really any good diet works. The issue is always keeping it off for those of us who are not sleeved.
Check out the blog for the world according to eggface.
The SEI Protein is AWESOME - DELISH - YUMMY!
And it has a ton less carbs than Isagenix.
If you were close to me (Northwest Arkansas), I'd give you all my Isagenix stuff - I have a whole $300 worth of products I won't drink!
