I watch it, too, but know it's changed since it's inception. It was more about the lifestyle changes and learning how to live healthier in the beginning, but I feel it's gotten way more "commercial" and out to sell merchandise/items lately. Might be just me, but it seems like they're trying to find heavier people and push them harder (bigger, faster, more).
I can't wait for the special tonight. It is inspiring to see people change their lives. As someone who lost 35 lbs with WW only to gain it all back plus 5- I feel their pain. It was so incredibly difficult for me to go from "dieting to lose" to "eating to maintain." I can't imagine trying to keep 100+ pounds off.
