We all get to that point, believe me!
Firstly, well done on your losses so far! That's brilliant!!!
Are you using your syns?
Are you planning your meals or figuring it out when you get home?
Do you think you 'binged' because you've felt deprived at all?
Did you take your measurements when you started? That's always a good thing to do because when you have those weeks where the scales don't show much, the inches are disappearing instead.
Do you feel hungry at all whilst on plan?
Have you got other things going on that may be getting you down?
I don't mean to sounds patronising in the slightest, but I'm just trying to think of things that I've seen other people do that could be the reason for your bad day
