Renie,
When weighing at your PCP's office, use the baseline or the very first time you weighed there. It will give you a better overall picture of how you are doing. For example the doc who does my mammograms weighs me and she uses the last visit I had as her baseline so it's an overall picture of how I am doing. My PCP does the same thing. I don't compare to my scale at home or the scale at the center. I see someone at the center about every 4-6 weeks so I only worry about that amount of time for those visits. I see my PCP every four months right now so it looks good to see how I did over four months and even better for the doc who does my mammograms because I see her every six months. Hope this helps. No two scales are ever the same but every scale gives you a weight. So, in effect over a period of time you if lose 10 pounds at home you should lose 10 pounds on any other scale for the same period of time although the actual number will not be the same. Joy
