A few years ago I lost 20+ lbs and have kept off 15 of those for the last 3+ years. Ideally, I would like to lose 3-5 that have crept up over the winter. I'm not worried about that at all, as I always put on a few pounds in winter. They disappear in springtime.

The main thing I did is stop my Starbucks habit. I was having an grande latte and a muffin-cake thing every day, equaling 1000 calories before I got to work! That was unacceptable. I stopped.

I also started eating more fruit at lunchtime. That seemed to cut down on the amount of other things I was eating.

I was already riding alot at the time (28 mile round trip commute 3 times a week), but I added in a spin class every week. I would have done more than one per week, but that's all I could work into my schedule. I think Pilates also helped alot. I was already doing Pilates, but I started practicing several times a week instead of just my weekly class.

I also decided to make some major life changes that resulted in a Much Happier Me. That way, I was happy with myself and did not sabotage myself like before.

So in summary, I lost weight and have kept if off by:
-knocking bad habits
-eating more fruit, which meant I ate less of other things
-adding a spin class and doing Pilates several times a week
-getting happy with myself (it's an ongoing process)
