My sister told me about this site, and I love it.
I have 85 lbs to lose, down 18 at this point. So I still have a long way to go. It is hard to keep focused on the right things to eat with a family, isn't it! Though they are supportive, they are still eating things that I don't want to eat. Plus, as you said, I really would prefer if they were all eating healthier too. I agree that maybe they'll follow my path when they see my success, and over time we will be a healthier family.
I am focusing on unprocessed foods within a modified WW point plan and doing pretty well. (It's the processed foods that my family loves so they are not ready to give it up!)
My exercising has my two girls curious but hasn't inspired them to do much more than they had been doing. I know my hubby will get in the groove but he hasn't shown any interest yet. So I keep on with my walking, step, or cycling, and figure he'll join me when he's ready. Heck I wasn't going to do anything until I was ready, I can't force him.
Anyway, hang in there. Let's share some ideas on how to be successful for ourselves as well as trying to get our families to be healthier as well.
