I'm just about there...my BMI is in the normal range and I'm wondering how much I can expect my weight to fluctuate now. It's a bit discouraging to see the scale stay the same or go up a bit. I guess my question is....what is normal and at what point should I actually start to worry? My biggest fear (at this time) is losing control.

this is a great question, I'm very interested in knowing this too. It won't be long before I'm there!

I kept losing even after I hit my goal of 150 lbs (I'm 5'8"). Not quickly, but over three months I lost another 12 lbs and I have settled at 138, plus or minus 2 and it's pretty comfortable to maintain. I guess you need to let your body figure out where it wants to be and you need to figure out how much a certain number means to you. If you are a few lbs above goal, will that make you nuts? Then maybe go below goal so that you have a little "wiggle room." If the scale staying the same bothers you, make another goal-- to exercise longer or faster, or enter a race, or lift more weight. Just something that makes you feel that you are striving for a goal and that will make you feel good when you've accomplished it.

Keep up the good work!
