For me, it's another kind of milestone, too. I've started (and stopped) Weight Watchers many times as an adult. I watched my mother do it as a child, and know that it can work, I've just never had the stick-to-it-ness to make it work for me. Until now.
It's not the fastest weight loss on earth, but given the events of the last year, I think it's safe to say that without the attention I've paid to it, I'd be at least 45 pounds heavier than I am right now.
And now that training for the triathlon is ramping up, I'm only expecting good results.
While it's most easy to measure the results in pounds, I've noticed so many other things, too. I have more energy. I'm stronger. My skin is healthier. I just generally feel better--both physically and mentally. I'm still fat, no doubt about that, but I'm actively working towards a healthier lifestyle, and that makes me feel good.
