Hi E.,
I can relate!
Let me tell you what I've been doing with some success:
Firstly: My sister and a friend and I started emailing eachother daily/weekly with support and challenges to help ourselves be accountable to eachother. Nothing fancy. Just "Hey girls, last night I had chicken and vegetables, and skipped the bread. Tomorrow I'm getting up 5 minutes early and doing jumping jacks." So doing the emails, I got support and also (in my mind) a little competition to spur me along. Doing this I lost 5 pounds! Then I got pregnant with DD#2! Sigh.
Secondly, I don't eat after 6:30-7:00pm. Even if I'm hungry. Because the truth is, I'm really not hungry. And if I was hungry, I'm really in no danger of starving to death. :)
Also, try to stock the house with healthy fast food: blueberries and yogurt, fiber cereal, salads in a bag, etc.
Thirdly-and this is the kicker-You have to expend more calories than you take in. I know you know this. Having kids makes it hard to find the time and energy. But if you are already walking for an hour, perhaps you can take it up to a jog? Jog 10 mins, walk 5 mins, jog 10 mins, etc. Get a pedometer! You tend to walk more with a pedometer than just timing your walks.
Also-if at all possible-maybe you can take a class(tennis, salsa dancing, volleyball) through your city. That's the best way to get in shape, really. Just having fun and YOU time. You'll start feeling great in no time!
Now if I can just take my own advice!
If you would like to email eachother with support I'm totally into that. I need a little motivation myself.
Take care and good luck! Get out there and do some lunges!
