Weekend struggles

I've had a dreadful weekend diet-wise. I've gone way over what I should be eating and I'm disappointed in myself. The problem is my sister! She is 8 stone 4lbs. She, seemingly, can eat whatever the fuck she wants and not put on weight. She came over on Saturday with the kids. First things first- put the kettle Plumptious (don't worry, she doesn't call me that, I'd thump her!!) and out comes a cake she had leftover from a party. "Why don't you just have a little slice, everything in moderation?" Yes, that's fine if you're you, skinny twig, but I CAN'T do moderation, that's why I'm obese, clearly. I had the bloody cake.

Next I got out the butter and french bread I'd bought, as I know they all love real butter and aren't so keen on margarine. Of course Plumptious can't NOT join in by this point and tells herself 'sod it'.

And so it carried on. Culminating in them leaving at 1pm yesterday (after lunch at disgusting god it was good McDonald's as it's the start of the children's summer hols!) but me not being able to stop myself from buying Doughnuts and Cookies later on- which is absolutely not skinny twig sister's fault! That's all my invention.

I have to try stop that kind of behaviour. It is so completely unhelpful. Once I feel that I've 'gone off the rails' I give myself the green light to stuff myself as much as possible. I know it's ridiculous but I don't know how to unlearn it.

All I can do is stop today and hope that my weigh-in on Friday doesn't reflect the gluttonous weekend. Maybe I can be extra good this week and try claw back some of those calories. I'm having a low fat sandwich for lunch and a no-carb chicken salad for dinner. Wish me luck. This losing weight thing isn't easy is it?!
