i am currently 20st 7lbs, my height is somewhere between 5 7 and 5 9 i am aiming to lose 10 st all together, i am really worried about how my skin is going to be afterwards, my mum keeps saying that because i am young i shouldnt have too much of a problem. I am only 20 but i have had a baby so i do have lots of stretch marks etc. Do you think i will need a tummy tuck at the end of all this? :help2:
