I'm worried about this, too! I have lost over three stone and no signs of loose skin so far. My tummy is fairly firm - my thighs and arms are ok. I have at least another 3 stone to lose. My question is, at what stage do you "know" whether you're going to get loose skin or not? When does it start going saggy for most people? I'm hoping the boobs don't go either - I don't have much in the first place, so I'd hate it if they went south.
I'm hoping my age, combined with my tight-skinned genetics will serve me well. Oh and body brushing, moisturizing, salt scrubs, MSM, weight training etc.
