I wonder if other have has a similar experience while Testing with the Libre .As Type 1 for 50 + yrs my finger tips were always tough and sore so buying into the Libre really helped me in several ways ,but especially I have noticed this , (The following is just a random example ). By using the Libre I have noticed that a BG level can take different length of time to bring it down to the required level ,using the same amount of Novo Rapid . Can anyone offer a answer ? To me this suggests that the same level can have different densities ? Is this possible or what is the correct answer ,

Hello @Wjohn - I also use the Libre and yes there is a noticeable difference in readings vs my bg meter as the Libre is testing sub cutaneous fat rather than blood, so it can be out by about 20 minutes as a rule of thumb. I take it you are still using your meter too whilst using the Libre so hence the variable is noticeable because of this ?
 
Do you mean your correction dose acts differently depending on the time of day? This can be affected by insulin resistance at different points of the day, bassl rate, what you ate and if fatty it may still be acting, stress, how high you were and various other factors like this.
 
I think it depends on all sorts of things..
I think it's just being able to notice now!
 
Dear gavin86 and Juicyj ,thanks ,sorry but I'm not explaining it very well ,but it is some of the factors you say .With using the Libre frequently and double checking ,what I am trying to explain is ,here is an example at random ,
Starting from a level of say 6 and having an intake of porridge which takes me up to a level of say 12 my and knowing my standard NovoRapid requirement for ,brings it down to 8 in 1 hr .So with all things being equal ,same insulin ,same time of day ,same stress levels etc.,if I now have a meal of fish and chips that also takes me up to 12and no more ,the same quantity of NovoRapid will now take up to 2hrs to bring it down to 8 .I am puzzled by the time difference ,it seems to me that my quick acting insulin takes longer to break down the sugar intake depending on what the type of food intake it is .
Hope I've got it right this time.

Hey, everyone is different, but I've found that fat slows down my uptake of carbs. Also, some protein ends up becoming glucose (up to 40% but it depends on a lot of things). Also protein takes longer than carbs to get there generally.

Also remember low/high GI changes absorption rates. You will get less of a sharp peak with low GI, even if it's the same number of grams
 

Basically thats right.......

A meal of fish and chips has considerably more fat than porridge does and its the fat that changes/slows the release of glucose into the blood stream...
