The basic foods are any meat or fish, shellfish, eggs or cheese - and a limit of 10 percent carbs on what I add to them - so foods which are less than that I can eat quite freely as it is difficult to over eat. I also only eat twice a day, early and late - that makes going out for the day very simple as I don't need to worry about packing foods or finding them when out. A fast breakfast is scrambled eggs with grated cheese added when almost cooked, then thinly sliced tomato on top, I put the plate over the top of the mini wok I cook it in, and the tomato is just lightly warmed up - I do mushroom omelettes too, sausages with a high meat content, a mushroom sweet pepper and courgette stirfry - sometimes cooked meat from the dinner the evening before, or maybe a tuna salad, or eggs and cheese in a salad.
For dinner there are so many choices - I do cauliflower quite a lot, but also aubergine, celeriac, courgette, some already prepared stirfry stuff is low enough, it is just a matter of going through all the veges you can think of and checking the carb content. For dessert I usually have frozen berries and cream, but I do need to be firm about using a small bowl.
I have just - almost 2 years after diagnosis, begun to experiment with making bread adding in low carb fillers as normal bread is just so high carb. I would advise getting normal blood glucose levels and Hba1c before trying anything high carb, particularly if you need to lose weight as well.
When checking the carb content do take into account that the US sites include the fibre in the carb count, so it has to be deducted, but the UK ones do not, they list the net carbs, the digestible ones. There are also sugar alcohols, which we can't digest but our gut flora and fauna can - I avoid those, as my insides took some time to recover from the party that went on in there - I thought I was going to become geography I was so inflated from the gas they produced.
