I did have mini-goals set up for myself. I made them though with the full intent of knowing that it was just something to shoot for. So there was absolutely NO disappointments if I DIDN'T meet them. Though it was FUN and exciting when I DID meet them. When I got down to the near end, the goal line so to speak, I elminated the time frames altogether. I was just happy with any loss at all during any given week.
In order for me to keep losing steadily and to meet those mini-goals, I kept decreasing my calories. When that was no longer an option, (didn't want to go too low) I just really, really STUCK to my calorie allotment, eating really high quality foods. I also kept increasing my exercise. I was up to 2 hours a day towards the end.
I had to lower my expectations as I got closer to goal. That's all there is to it. Weight loss will slow down the closer you get to goal.
You have to know yourself. If you think 7lbs is too ambitious and you will be disappointed if you don't make it, then by all means lower it. If you think it will HELP you stay on plan and be even more vigilent, I say give the 7lbs a go. I know that wasn't very helpful, but it really is an individual thing.
Good luck Tricia. I know whatever you decide, you are a definite LOSER. I mean that in a good way, but I think you knew that.
