I normally don't post on this forum, but I just wanted to step in and say that weight loss requires
patience patience patience. The scale just doesn't move that fast! If you are following your plan, you should lose, but sometimes it takes a while to see it -- that's not just true at the beginning, but all the way along the journey.
Sometimes you will sit at one weight for a while and the next day the scale moves several pounds! It's not the thing you did the day before that moves it, but an accumulation of things coming together! (including water weight, which is another issue).
Take a look around this site and you will see many people dealing with this exact same issue, all along their journey. The scale just doesn't move as quickly as we want it too!
So, scream if you like, but know this is normal, and if you want to be successful you have to come to terms with that on at least some level!
