Hi emzy, you need to stop worrying about what advice you didn't receive from the doctor, if they had advised you as to what you should be eating, it would likely have been terrible advice anyway, better to listen to folks here that don't have to follow government guidelines, there is much more useful advice here than the nhs, weetabix and cereals in general are a no no for most of us, you should try to look for alternatives, personally i have full fat greek yogurt with berries and milled flax which doesnt effect my bg hardly at all but lots of folks have eggs and bacon and because that is extremely low carb they find that works brilliant of them, your 2 weetabix from memory would have had something like 30g of carbs therefore that is bound to push your bg up unless you are lucky enough to be able to tolerate that amount of carbs but from your numbers id say you can't, we are looking for foods that give us a rise of no more than 2mmol 2 hours after eating, I'm hoping I'm not teaching you to suck eggs here but carbohydrates turn into sugar when we eat them, there is always debate here as to how many we should be eating but generally accepted by everyone is reducing the carbs you eat reduces the amount of sugar you have inside, so if a meal contains carbs, it basically contains sugar so you cannot expect that not to put your sugar in your blood up higher, so therefore it would make sense to reduce that, some people prefer to do this as well as reducing other things like fat, personally this makes no sense to me but hey ho, some people reduce there intake by reducing the amount they eat therefore consuming less of everything including carbs, which ever way you choose, the carbs are whats doing you no favours, there are apps if you have a smart phone you can download which with a bit of trouble you can record what you eat (simply by zapping the bar codes on packets often) the nutritional content of the foods you have eaten will be broken down for you so you can see what you've eaten, coupled with the readings from your blood you can get a picture of what makes your blood sugar go up and what doesn't therefore giving you the opportunity to stop or reduce the foods that spike you, try "myfitnesspal" or "carbs and cals" i do hope this makes sense please say so if not.
