How to lose weight before tummy tuck?

Hi Everyone, thank you for accepting me. I am a mum of 2 beautiful kids but after 3 pregnancys (my first son passed away) and 3 C sections my tummy is a mess. The time has come for me to get my body back and have decided to go and have a tummy tuck done. I have seen one surgeon in melb and i need to drop about 10 kilos. So i have started working on that but in the mean time i wanted to join this group to get ideas about surgeons and i guess just get support. I look forward to all the stories and getting to know you all… many thanks
