Edit starting weight
You can edit your starting weight in the Weight & Goals section of your Plan Manager Settings. Click the Edit link next to your starting weight.. Make sure your starting weight is above your goal weight. If not, you will need to edit your goal weight first so that it is lower than your starting weight.
When you change your starting weight, your milestones and 5% and 10% Targets will re-calculate based on your new starting weight.
