How is it possible????

I have that issue too. My scale at home says I weigh 3 more pounds than the scale in my doctor's office. As long as you stay consistent with which scale you are referring to (either your home one or your WW one), you can actually see how much weight you are losing.

Pretty simple, you're using 2 scales, it's pretty unlikely to ever find 2 scales that'll ever weigh a person that same unless they are side by side on the same floor surface. Even then, it wouldn't guarantee it.

Pick a scale and keep that number in your head and go with it, it's fine to check the other scale out but don't let this make you crazy.

Would it help to only use the WW weigh in so you don't go bonkers feeling bad when it's likely you didn't gain at all?

I weigh at the gym, my home, the doc, another doc (not everyday or anything:laugh: just when I have appts. or decide to jump on it at the gym)... lol So I go by my home scale and it's keeps me sane. ;o)

Every scale is different.

The one at our gym (which is digital) is 5lbs heavier than the one I have at home (analog). Since I use the one at home more than the one at the gym - I go by the weight on that one. I do occasionally weigh in at the gym just to see what it says - and it is ALWAYS 5lbs over. I don't let that get to me. When they first switched to that one and I didn't have one at home - I was floored by my 5lb weight gain. It is actually why I bought one for home because I couldn't understand why the old one at the gym said one weight, the new one said another... got my home one and it matched the older one at the gym.

Could be any of a number of reasons. Home scales have different measurement mechanisms and are not calibrated, so there will ALWAYS be differences from one scale to the next. Also, your body will naturally fluctuate 2-3 lbs over the course of the day, so timing can effect your results as well.

My suggestion, pick 1 scale use only it. Then always measure at the same time of day (morning) while wearing the same thing (naked).

i like to put two 5-pound bags of sugar on my scale to make sure it's accurate before i get on.

The only accurate way to keep track of your weight over time is to weigh yourself at the same time of day on an empty stomach on the same scale. Even then you are looking more at relative measurements, not exact ones in the short-term and there's no need to check your weight every single day. Depending on your exercise and nutrition plan you may experience a change in body composition that results in fat loss, muscle gain, water loss, water gain or a combination of all the above and it's impossible to tell what happened just by looking at the scale in the short-term. If you are female you will have hormonal changes that cause small fluctuations in weight as well. Don't sweat the numbers, just stick to a solid plan, take pictures of yourself every month or so and maybe keep an old set of clothes around for comparison. When you feel more energetic, are stronger, faster and fit into your clothes better you will know you are on the right track. Also be aware that people with "more to lose" will have vastly different results from those who just want to lose that "last 10 lbs" or "firm up", add muscle mass, etc.
