I have 4 or 5 st to lose. I won't be skinny, but will look OK and not overweight if I lose 4st. I'm quite an athletic type when I'm not fat, and quite muscular. I'm also active (not as much as I could be but more day to day active rather than all out gym goer).
I've been worried about being left with loose skin. I'm 47. I managed not to get any stretch marks I'm pregnancy despite 2 massive babies.
