Hi Exit
I got into this fairly slowly. I don't count carbs in non-processed fish, meat or cheese. However, I try to keep my portions on the normal side. But probably more on the man size than dinky lady size i.e. a good solid portion but not obscence.
If it's processed, then I do check the carbs. If I'm using literally one spoonful of something in a bigger meal, then I ignore it.
My aim is for somewhere around 40-50 carbs a day. That means I can pretty much eat all veg (apart from spuds). I try to eat more of the filling low carbs veg rather than eg carrots and peas, which are higher carb. But if that's what's on offer somewhere then I don't get too uptight about it.
I am steering clear of most fruit at the moment because it just sucks up your carbs for the day. If I've had something carb-y early in the day then I try to be a bit more strict for the rest of the day.
There are a lot of people who are really hardcore and they get great results. But I know I just wouldn't be able to stick to that long term so I am going for the softly softly approach, tweaking and experimenting as I go.
Although current experiment with cake is not so successful!
