"oh just one cake won't matter, you've got to eat you know!"
With this you really have two options.
1) "One cake won't matter, but it easily ends up as more and that's what got me here in the first place." or
2) "I could eat the cake, but I'm saving my syns for (insert syns of choice here!)."
In both cases, the phrase "you've got to eat you know" is usually quietened down when people see how much I'm eating!!!
"Come for tea, I'll make it SW friendly" get there to full fat food - with a teeny side salad on.
When people offer to cook, ask what they're going to make.
If they say it's going to be 'SW friendly' ask them how.
Try and find out if they actually know the SW rules (even vaguely!!).
If people offer to cook, offer to bring something (either salad, dessert or even a side veg dish.) that way you can fill up on what you know is ok and enjoy a little of what they've cooked too.
"Why are you eating an apple, don't you want some of this?" **wafts a big mac in my face**
Again two options
1) No. I've seen a report on what goes into them and also the lack of hygine of staff in fast food places (this is just something to say - not a judgement on any fast food employees out there!!).
2) No thanks. I'd rather wait until later and use my syns on (insert syns of choice here!!!)
Especially ones for mothers in law who despite being what I regard as a bit offensive to me and my feelings, needs handling without causing offence to them and their calorie ridden Bird's trifle....
Aahh! The most difficult one of all!!! - Options are obviously limited but my favourites would have to be
1) "ooh! I really wish I could but dinner filled me up - maybe later" or even asking to take it home instead! Once you're out the door, it's either in the bin, or in the husband!!
2) Take a fruit salad as well 'to help out and say thank you for cooking' - fill up on a lot of fruit salad (with a little bit of triffle so as not to hurt her feelings) and again, offer to take some home as 'it was just so lovely!)
3) Phone ahead and offer to make a dessert 'since she is doing all the work, cooking dinner'.
4) Brag about your weight loss and say 'ooh! I can only have a little as I'm hoping for a loss this week - can I have some fruit with it?'
5) On weeks you're at the out-laws, count syns weekly, only have a little of the triffle and smile sweetly at her!!!
