I like a bowl of porridge for breakfast most mornings and it normally doesn't affect my blood sugar readings badly. For example this morning my fasting / pre breakfast reading is 7.7 and 2 hours after a bowl of porridge my reading had dropped to 6.7. The other evening I fancied a bowl of porridge instead of my normal evening meal. This time my pre meal reading was 6.2 and 2 hours after the porridge my reading had risen to 9.6. So I'm wondering why the porridge has such a different effect on my blood sugar depending on what time of day I have it. FYI, in the examples above my level of physical activity was similar after both bowls of porridge.
