Hi Debra,
Unfortunately women find it more difficult then men regarding sugar free and loosing weight. I know how disheartening it is, I've been sugar free for 19 months and I've gone up and down. Low carb for me did work, I didn't cut out all carbs I just limited them, I cut out bread (which I don't really miss at all, it doesn't interest me much anymore but I've found bread doesn't fill me up as much so I tend to eat more then what I need so I'm kinda overeating). One of the family friends, she has been sugar free as well for quite some time too. She stuck with it, she does walk quite a bit and she has been really good. It took her quite some time but she finally started loosing weight and she's looking so much better and even younger! I do exercise every day though, but I work in an office so i'm sitting on my butt all day so I'm happy to get moving. Compared to days when i don't workout I haven't noticed a difference in the amount I eat, I do exercise at night though usually after dinner when my kids have settled and I get a moment to myself. Loosing those last few kgs can take a little time however stick with it, keep tweaking things until you find something that works.
