Hi - I had a quick peek at your Nutrition Tracker, and IF you are recording ALL that you eat, going back to the beginning of August, you are being far too restrictive. It isn't healthy to be going down that low and can have long-term effects. 1200 calories is the minimum recommended calories for a sedentary average weight woman, to ensure that she is getting all the nutrients required. There are many days you are around the 800-900 mark. This is counter-productive. Odds are, if you increase your calories you will find that in time you will lose the weight, and it will also be much easier to maintain, because otherwise your metabolism gets stuffed, and as we all know, a slow metabolism is NOT our friend :-( The other thing to note too, is that using a very restrictive diet, is NOT the way to learn life-long healthy habits. Often what happens is that when a person reaches their goal, they go back to eating how they were before, OR they don't reach their goal because they have fallen off the wagon long before. Yo-yo dieters are notorious for this.
As far as your comparing weight is concerned, you have really answered part of your query yourself. You can't compare using different scales. I only weigh on my Medical Centre's very large hospital-type scales, and only before lunch and immediately after having been to the loo. (It is amazing how much weight is lost that way - LOL!) I also only weigh in the same clothes, but on the odd occasion I am wearing different clothing, I know the difference in weight between both lots. (sounds a bit nit-picky but I am a stickler like that - obsessive personality trait:-)
I wouldn't be concerned about the scales, or even the tape measure. Instead I generally go by how my clothes fit. Other indicators of how well you are succeeding is:
* Your energy levels
* The condition of your skin and hair
* Your BP and/or cholesterol/blood sugars if they were a problem
* People telling you that you look good :-)
* The quality of your sleep
I don't bother about the measuring tape because I can measure and then measure again immediately after, and it is different. You just need to hold the tape in a slightly different way for this to happen, or take a breath in, whereas the other was breathing out, or even how you hold your stomach (tension.) My Dietitian has occasionally measured my waist, but we generally gave up on that long ago. I had lost about 50lb, but only a couple cm - not even an inch - around my waist. BUT I had gone from a NZ size 20-22 to a 12-14 top and 14-16 bottom. My fingers are smaller - my feet slightly smaller - my wrists a lot smaller, even tho' they weren't big in the first place - my face is much slimmer and my shoulders are narrower.
My best gauge of success came when I went to the Dietitian one day. I knew that I had lost a fair bit of weight because my fitted, side-zipped trou were getting baggy. I found out how much too baggy when I stood for her to measure me - they fell to the ground, totally unaided - LOL! My daughter went one step further. She had been losing weight and went for regular brisk walks around town. On this particular day HER trou fell down, but that wasn't all - they took her knickers with them
(it was a hurry up for us both to get new clothes :-)
