What do you do when you are in other people's houses?

We are spending the next six weeks at my in-laws (we live overseas so do this every other summer). Pils are very laid back but mil is now doing SW and is on a strict low fat diet. I wanted to use this time to eat low carb but feel bad about bringing full fat dairy and other delicious low carb foods (high fat) in the house.
Do you think i should suck it up and eat low fat - this way of eating does not work for me at all...or buy the food I want even though it is not what she would eat?
I have about a stone to lose and eating low carb is so much easier when in the west. Thanks

I would bring my own foods. Use their basic foods and have a knob of butter with veg etc full fat milk anyway is only 4 per cent.

Some vitamins are fat soluble so you could explain it that way.

Souds like you'll have a fab time.
