You might be embarrassed over photos and measurements today, but you will be so glad you did once you have made just the smallest bit of progress. So get that measuring tape out right now and get it done, also TAKE A COUPLE OF "BEFORE" PHOTOS. I didn't, I just couldn't face it and now I have no idea how many inches I've lost, and the only "before" photo I have is with me facing front standing next to my husband. It's okay, but it would have been MUCH MUCH better to have front, side and back photos to compare with current ones. I think the back side of me is probably the most improved, but can't say for sure. I think the difficulty many of us face with that sort of thing is that it's absolute proof of the problem, a step out of the comfortable land of denial. Believe me once you've drop 10-12 pounds, take a couple more shots and some measurements, because that in of itself is a TON of motivation! And believe me it's difficult to stay motivated all the time, you have to grab or manufacture it every day.
And I'm totally with you on the mom factor. My kids are a great source of motivation. I want them to be healthy, and the best way to ensure that is to lead by example.
