Congrats on getting active with SparkPeople - it's a great community, wonderful resources and fantastic support- it's also lots of fun and easy to make friends because we're all in this together. It sounds like you've been off to a good start - don't worry about 1 lb - it's normal for our weight to fluctuate and I can actually see 2-3 lbs change almost daily, going up and down, so look at the overall trend, not every little bump along the road.
Sometimes the best way to start is to just pick a small goal such as drinking 8 glasses of water a day or eating 5 fruits and veggies plus a small exercise goal such as increasing whatever you've been doing by 10% - I like the way a HEALTHY LIFESTYLE is emphasized here instead of a 'quick fix wonder diet' and another nice thing about SparkPeople is that we have permission to be human - we don't have to change everything at once or be in a hurry to reach our goals. Take a few baby steps and then a few more and before you know it, you'll have completed a long journey - I hope you enjoy this community as much as I have - it teaches us how to make positive lifetime changes because that's the only thing that will work over time!
