With every 10-15 pounds of weight you lose, you'll want to update your current weight. If you go to your Start page, down the left side you'll see your weight loss goal. Click on the red Change link next to it, make sure your current weight is correct and click "save changes". Your range may or may not change, but doing that will ensure your range is accurate based on your current info.
"You may have a fresh start any moment you choose, for this thing that we call "failure" is not the falling down but the staying down." Mary Pickford
