hi, i'm in a similar situation, no husband but family history of diabetes and need to lose weight as i don't want to end up following in the family footsteps. I'm a stone and a bit down and have 7 to lose.
This place has great resources and support. I try and keep my total carbs under 30, and it's working slowly for me but i have other health issues and most of my medications are associated with weight management issues, so i'll get there. One not of encouragement is i measure as well as weigh and my measurements have encouraged me more than the scales. So I know things are changing in a good way. Good luck
