I salute all of you parents who are making healthier choices for yourself in order to be around longer for your kids and to set a good example!!
I lost my father when he was 56 to a heart attack; he also had diabetes. Yep, you guessed it, morbid obesity and horrible eating habits. I also watched him be continually frustrated while eating on a diet plan, which he never really committed to and cheated on every chance he got. He never, ever could see the positive side of making healthy choices...and it cost him his health and longevity. He never knew his grandkids.
So, y'all hang in there. I don't have kids, but I feel like a parent a lot of the time because I'm a teacher.

I admire you more than you can know for sharing your life with kids and helping them grow. Just remember that taking care of yourself benefits you AND them, in ways you maybe can't even imagine yet.
