Hi again Beetroot,
What I found when I started testing is that almost any amount of cereal for breakfast (porridge, All Bran, Weetabix, Shredded Wheat etc) all took my blood glucose levels to 10+. I tried eating amounts as small as 30g but that didn't seem to help in any way. Toast does the same. However, I can eat quite a lot of carbohydrate in the evenings. I've changed my breakfast to variations on tomatoes fried in a small amount of olive oil, grilled lean bacon, low-fat sausages, mushrooms, baked beans etc. If I have toast I have no more than half a slice of Burgen bread (lower carbohydrate than most other breads). If I do have cereal now I eat Lizi's granola (Low GI nut based) cereal.
I reckon that change has been the biggest factor in my improvement.
For lunch I have a mixed salad including chopped up fruit with smallish amounts of ham, chicken or fish (tuna or mackerel).
In the evenings I am more adventurous but tend to still be careful about the carbohydrate and only eat things such as brown rice, spelt pasta etc keeping well clear of white refined carbohydrate products.
I eat lots of fruit and vegetables, also small amounts of mixed nuts, also yoghurt at some time in the day. In addition, these days I drink very little alcohol and when I do it tends to be red wine.
It hasn't been difficult at all for me and when I could see the constant improvements that kept me well motivated.
Best Wishes - John
