It's sort of a small meal every 2-4 hours.
For example I would eat
- a tomato
- an avocado
- 1/4 of a full cucumber
- half a tin of chickpeas
- seasoning
Which would be around 400 calories in 1 sitting.
All those foods you mentioned are very bad. White bread is perhaps the worst food for a hypoglycemic. Pizza and white pasta are likely to contain the same fast acting properties. Potatoes are a healthy food, they just cause a rise in blood sugar and therefore should be avoided.
As time goes on you may be able to tolerate some occasional sources of fast acting carbs. I've heard from people at both ends of the spectrum, those that now have no GI issues to those that need to maintain a strict diet indefinately. What's probably a dead cert is that you won't be able to consistently eat the stuff you used to. Occasionally, perhaps
However there will be a mental shift in your perceptions over time and even if you think now you can't live without certain foods, you may evolve to a point where you just dont' want to eat any bad stuff. For me personally I used to load foods with sauces, as well as the hidden sugar. Now that has been removed the natural flavours of foods have been enhanced, and what may seem bland to others its actually quite enjoyable.
The blood glucose monitor is a finger prick. And yes it can be useful for keeping an eye on whats happening for the many 'maybe' foods such as fruits or root vegetables. It will beneficial to have some readings to take to the endocrinologist.
