So glad to hear you write about health and and family and not about reaching some magic number. You have lots of good reasons to help you reach your goals.
Be sure to journal all of what you eat, and keep notes also about how you feel. What you to right and when you slip up as you will do - it's human. It's important to know why you did such as emotions, temptations, memories, enablers, etc and then you are better equipped to jump back on the food plan. It really isn't a diet except that if you don't eat, you die! LOL
It is a place to track your food plan - which ever choice you make that works best for you. You can get feedback on any number of options 24/7.
Spark People is a wonderful place with lots of great articles, message boards, blogs, recipe links, and exercise suggestions & videos. You can get as much or little out of it as you are willing to put in. I wish you lots of luck and encourage you to stay with it.
