I hear you mrsmac, I'm 5'4 and should be around the 60kg mark. I was 85kg when I started this and have got down to 77, it doesn't sound like much, but that has been a struggle to lose this year what with doing 3 cycles at the same time!
I use my mother as motivation to keep going, she was tiny before having my brother and I and now she is huge and has so many health issues, I truly don't want to end up like that, it's so difficult for her.
You will def feel better even if its just a couple of kgs lost. Every little bit counts and does make a difference. Good luck with it.
