I would say I am naturally slim but not skinny and it has varied through the years. Like Piffle I put on weight when I first got a car, for example. I also put on a lot when I used to have a cooked lunch at my work canteen and then a dinner when I came home!
At the moment I am probably about the same as I was before kids.
I think I am one of those lucky people who doesn't have to watch what they eat too much. I have a friend who eats salads, etc all the time and still can't losed weight.... but then she has a desk job and drives everywhere because of where she lives, whereas I am a sahm running around after kids all day, we have 2 flights of stairs, I do quite a bit of decorating at home, walk into town regularly, etc. (Don't do any "exercise" though!)
In terms of what I eat"
Breakfast - coffee and toast (with marmalade), maybe juice as well.
Coffee and biscuits mid morning
Lunch - sometimes leftovers from night before, otherwise sandwich. Sometimes soup and toast in winter. Sometimes I don't eat much at lunchtime if I'm not feeling hungry.
Coffee and biscuits/chocolate bar mid afternoon
Dinner - largish portion of something usually home cooked but not particularly healthy, eg chicken casserole, spag bol, chilli, roast chicken, curry, stir fry, pasta etc.
Milk and biscuits after kids have gone to bed while watching tv.
(I can see a theme developing about the biscuits!)
I eat the odd bit of fruit during the day but I would say I often don't get all my 5 portions of fruit and veg in!
I don't think I'm a very good example to follow actually!
