It probably will
The same is happening to me, had a few weeks off and by the 3rd day back on I was holding +2lbs
It's shifting very slowly indeed, didn't check today.
But it's all good as I know once the scales take off again I will lose very well and I will notice each lb
I want to be under 10st by september and even though that's only 8lbs away it feels like a mountain to climb but I WILL do it
