I realise we're all different
However, I never knew that carbs was a 'thing' before I joined Mumsnet.
I read all the time about people low carbing/cutting out carbs/eating too many carbs.
My experience though of people who are not overweight, is that they don't tend to worry or think about carbs. They just have a little bit of what they fancy, with the emphasis on a 'little bit'.
It must be exhausting to have to watch these things all the time and I do sympathise with people who feel they have to, instead of eating less of everything/exercising more.
And I wholeheartedly agree with the PP who said it's a lot to do with stomach sizes...which is why I think a lot of kids today are being set up for weight problems in the future, due to the volume of food they're often given to eat in one sitting.
Some 5 and 6yr olds eat dinners the size of mine.
