Well, you are right that everyone is different, but if it helps you gauge what to expect, I will share with you my experience.
I started raw with a goal of losing 30 pounds. Immediately within the first 3 weeks I had effortlessly dropped 14 pounds without even being aware of it or trying.
As of now, I have not lost a pound since then, and I think my body is happy at the weight I am at, although I would like to be about 15 pounds lighter.
To sum up my experience, the initial weight loss was a breeze, but I found it nearly impossible to lose weight after that.
