Lest I disappoint someone who shall remain unnamed (you know who you are), I have to tell a little bit about how I've lost weight... I've needed and wanted to lose a few pounds for about a year now... each time I would start trying and show some success, something would always happen to sabotage my efforts... a fellowship at church with only chips and desserts, a birthday party, etc. Then, when I was a little way into my weight loss, I would quit. Usually, it wasn't intentional, it just happened due to the circumstances at the time.
When I got on the scale and saw a number that was ridiculously high (for me), I decided it was time to stop "trying" and do something about it. At first, I just changed the way I ate. In stead of eating a turkey sandwich, chips, and a couple cookies for lunch, I switched to salad with lite dressing, yogurt, and graham crackers. When my students give me a cupcake or a cookie, I wait until they are out of the room and throw it away. These changes were difficult in the beginning, but now I'm used to not eating these things at all.
When I started seeing some pounds come off, I was even more motivated, so I started adding cardio workouts (I use Leslie Sansone and Chris Freytag DVDs). I've recently added light hand weights, too. I've also started keeping track of everything I eat on everydayhealth.com. I measure out portions (what I thought was 1 serving was really about three), record them online, and then I'm able to see what I've really consumed in calories that day.
With all of these "efforts" combined, I've lost in the neighborhood of 20 lbs in about 2 months. At first, the pounds came off really quickly because I went from eating very poorly to eating healthfully and from not exercising at all to exercising quite a bit. It's moving a little more slowly now... I've been losing 1-2 lbs. a week (which is what people suggest). I would love to lose about five more pounds.
Now, I exercise every day and eat more healthfully than I ever have. I have much more energy and it's so nice to be able to need a size 6!
