Do they add pounds to the weighing scales at WW?

[Mammalian]

I find Weight Watchers brilliant.. over the years, any time I feel my weight creeping up over a stone more than I'd like, I rejoin and it kicks me back to a good start.
One thing I always find weird though is the scales seem to be 2-3 pounds more than at home. Anyone else noticed this?

I always find this too!

Could it be the time of day you are weighed? If I weigh myself in the morning I am often 2lbs or so lighter than I am in the evening.

Possibly the time of day... although usually always in the evening for both

I weigh in on a morning before breakfast. I weigh myself at home in the clothes I wear to official WI beforehand and there is absolutely no difference between scales at WW and my home scales.

If you weigh yourself at different times of day, in different clothing after food etc, there will be a difference. I can easily weigh 3lbs heavier by bedtime for example.

This is not a weight loss forum This is about lifting weights to get strong.
