Can I invite everyone to share their food and postprandial readings to understand better how a particular food affects our glucose levels? I will start with my experience since last few weeks. I always get my meter reading under 6 if i eat cheese+veggies or yoghurt+nuts, or fish+veggies etc however i did an experiment with lamb kebab (homemade from mince meat) yesterday. Readings were a surprise as below:

BG after 1 hr 4.9 (same as at before meal)
after 2 hr: 5.8
after 3 hr: 6.6
after 3:30 hr: 5.8

I believe it has to do with meat slow absorption? Can you guys share your experiences please? Just to note i ate about 100 gm kebab with some salad not exceeding 8 carbs.

I am not sure how to get this message out but it would be extremely useful if we get first-hand knowledge of postprandial BG readings and the type of food we eat. I believe this is the most useful information to share among the community and will save everyone countless readings based on other's experience, or at least will have a starting point to test our own response. Can this topic be promoted or moved upwards by moderators? or if anyone has a site or link to any other thread related to this information ? I am not interested in the guy on YouTube who did some experiments with some foods with his wife but to just grab that 30 second information you need to listen to his useless stories for 10 minutes just so he can run more ads
 
Actually i just found an interesting study,

https://academic.oup.com/ajcn/article/89/1/97/4598292

Please look at the table. You can download PDF. This answered several of my questions because they showed peaks at 60, 90, 120 minutes with different foods in healthy persons but still can compare to how food contributes to glucose levels.

TABLE 1
Plasma glucose responses to consumption of foods with a low, medium, or high glycaemic index (GI)1
 
the problem is we are all individuals and our circumstances and bg will change from minute to minute.
I could have the same meal on Monday and Tuesday but because any or all of my:
Sleep
Stress
Activity
Hormones
Medication, and many other factors
were different then my bg would different too.
Yes food plays a major part but it is only one of many parts and variables
 

Diabetes is a chronic condition that has to be treated holistically - all the factors @MrsA2 has listed play a significant part as individual cogs in the wheel of keeping it at bay. I've already found 2 months into this journey that if only one of these is out of synch, then there's a negative bg differential.
 
Probably the best thing you can do is use Libre sensors for a while in combination with a food log and your finger prick tests, and their continuous recording 24/7 should show you exactly what your reactions to various food combinations and other issues will be. And that information is what you need to work with.

Other peoples' results can be interesting but are not really useful for me because my diabetes, other possible health issues, and general circumstances are completely unique to me. However, in general I eat a combination of protein, full fat, and some low carb vegetables/fruits which tends to keep my levels nice and stable. If I eat high carbs then I'll see a definite post meal rise. Fats and higher carbs combined can result in a longer and possibly delayed "bump" rather than a sharp rise. As already mentioned many other things can affect glucose levels, and sometime they can result in overall higher levels though pre and post meal figures remain stable. But as long as I can keep my glucose within my target range then I don't worry over much about very fine details over which I may have little or no control.
