I'm little (in height anyway!) and I needed to lose nearly two and a half stone to be comfortably back inside the 'normal' weight range. I'm not diabetic or pre-diabetic but I could see that in my future if I didn't make some changes.
So I'm trying to do the 8 week 800 fast. Was 11st 3 when I started, halfway through the second week I'm 10st 10 and feeling a lot better about myself, lighter and more energetic. Long may it continue!
