Ok, I'm overweight. I get that.
Luckily at 5'7 I carry it well but I'm aware and feel overweight and have adjusted my diet to eat more healthily.
I started 3 weeks ago and this week people have commented about how much less bloated my stomach looks and how clear my skin is now.
The first week of starting healthy eating I lost 1lb. I accept my loss will be slow as I've not yet started a regular exercise routine alongside it.
Week 2 my scales say I've lost 4lb.
This week is the week I've had comments about how I look like I've lost weight.
So I get on this morning and I e PUT ON 7lb in a week 
To me that seems a MASSIVE amount to change in a week (4 seemed a lot to me!)
AIBU to think something is wrong with my scales or anyone she'd any light on how that can be possible?
