I think you need a reality check. 10 lbs in the first week is a big loss. You cannot expect this to continue. 1 lb of fat equals to 3500 cal deficit. You are also not extremely overweight, so your future losses will likely not be that significant. 2 lbs rather than 4. You also do not need hope. You need a life style change and the determination to pull it through. Hope is for the weak.
