Disastrous day! 
Went to PIL's for lunch. They are 88, lovely but quite set in their ways. They think I'm faddy because I drink herbal tea (have to take my own tea bags when I visit
)
Usually if we visit, depending on how MIL is feeling, either she will make a roast lunch, or if she's not been so good I'll make a casserole to take. MIL has been feeling chipper so said she'd do lunch today. She decided that people would have had enough roast meat over Christmas, so instead she delved into the Mary Berry cookery book she got for Christmas and made..... PASTA BAKE, followed by STICKY TOFFEE PUDDING
She was so pleased with herself. I had no option but to have the smallest possible portions. To make it worse, dh and I were in a sunny place over Christmas / New Year and neither of us had any roast meat and I was looking forward to the usual!
Then to top it off, before we left to drive home, FIL pulls out a huge pile of sandwiches that he'd made, and sets them down on the table alongside a Victoria Sponge filled with jam and cream. MIL is proud of her featherlight touch in the baking arena. I have never liked cake of any sort, but for 20++ years I've been smiling and graciously accepting.
I was completely unprepared for today's food. Dh, is lovely and kind and supportive of everything I'm doing, but I know he would not have supported me if I'd refused point blank to eat a morsel of MIL's cooking. Which was what I wanted to do. I feigned a headache at teatime to avoid the worst excesses of the sandwiches and cake, and sipped delicately on my herbal tea. But in fact the headache is real, I feel awful, and as though I've put on about half a stone in an hour.
Rather dreading the scales tomorrow (and the next day), and I am definitely NOT going boot-camp lite this week.
