I have lost just over 7.5% of my body weight so far. Sadly, this only equates to 18% of the weight I want to lose altogether, as i need to lose nearly 42% of my original body weight to get to my goal. However, I figure it's still a good step in the right direction! 
So, what % of your body weight have you lost, and how far have you got to go to reach your target?
