What foods spike / don't spike your BG? Under continuous monitoring?

Hello,

I have been playing with a first time continuous monitor sensor for the last 2 weeks. I'm testing different foods to see what works best or worse for me.

I was wondering for suggestions of what to test or not to test based on your experience.

I have learned things like:

- Not to use low fat milk, lactose free even worse (BAD) - I now use a single drop of 35% fat cream on my coffee. No change in the machine.
- To season the salads with olive oil. Seems to have a positive effect.
- Meat is good, but LEAN meat in huge amounts, does raise my BG. Not gigantically but it does. Lesson: meat with moderation with some fat in it.
- Morning stress and movement raises my BG, since Im very low carb, I believe its the liver dumping it...
- Best (carb) side dish is dark beans (in small amounts the BG raise is moderate) - but it still raises.


Could you please speak of your experiences (using a continuous monitor) so others like me can learn and test things?

I want to test fruits, vegetables, learn some tricks...
 
Libre 2 user.

I've just posted about baked potatoes, trying to work out why they don't spike me.

I think a moderate rise in BG is fine as long as your BG drops back again.
Then again I'm a bit more relaxed in my targets.
I have double cream and butter in my coffee in the morning, which seems to raise me a bit, but then again Dawn Phenomenon.
 
I found the CGM experience to be interesting but both inaccurate and annoying (two failed). The one that worked read consistently low, but showed a pattern: the interesting thing for me was what was happening in the periods when I wasn't testing - eg in the first hour. Example - hot milk (in a latte) produced an amazingly quick but shortlived BG rise and was gone at the two hour mark. Not too keen on the big bg rise but my system cleared it really quickly - I'd never have known.

I also found an interesting pattern while asleep - dropping to very low figures (which I don't completely trust) at 4am followed by a huge liver powered bg rise that can continue for over 12 hours.
 
Hello Kenny, I have had a wonderful experience with my first ever Libre 2 (13 days), finger prick ones were garbage, consistenly gave me around 2.0 higher readings than Lab results (I went to the lab every saturday for weeks), same s**t results consistently.

I had a glucose test tolerance test last week (drank 75g of pure glucose) and had blook checks before and 2 hours after. The Libre 2 gave me a perfect match with lab with a near 20 minutes time gap. (Surpringly low numbers 4.6 before 5.8 after according to Lab) I thought libre was rubbish, but then proved right. I did loose some results after the peak (when change is too fast it refuses to provide numbers)

As for night time results, I have a similar experience (on a strict diet to loose weight and control T2 - less than 10g net carbs), during night especially between 1am and 3am (variable), I drop to around 3.6 before the liver kicks in... then as it gets closer to morning hours startst raising and after waking up I can get into 5.3 (still fasting). But if I eat a lot for dinner (like Brie Cheese which is high fat low carb) and pleanty of animal fast, the over night levels dont drop as bad as with strict diet.

There is known bug with Libre 2 - If you are sleeping and put your body weight on it, it may give ultra low results like below 3...

What kind of carb side dishes can you get along with? So far I only eat fish/meat with green leaf (so almost no carbs).

Sorry to derail, how did the OGTT go ?
Did you get your 2 hour figure ?

pre was 4.6
post 2 hours was 5.8

My average estmated BG in January was 14.1 (A1C: 10.5%), so I was happy

What did your doctor/nurse/endo say about this marvelous improvement.
It would appear your T2 has mysteriously disappeared

LOL...

My endo got mad at me for eating less that 10/15 grams a day of net carbs.

She told me that diabetic diets should be the same as everyone else. In the menu should be *whole* potatoes, rice and pastas (she was only short of pure sugar). Recommended against keto (said not viable in the long run).

The course of action when it (diabetes) returns would be medication... also recommended to go get a retinopathy test.

I paid for this out of pocket!
 
That's a great blood result. I've never taken an OGTT so havn't been able to calibrate my results that way. However - allowing for the fact that they measure different things and there is some expected error - they have always matched pretty well (fingerprick, A1c and Libre) so I'm not sure I need to.

BTW, I know about the Libre pressure issue - but it's not a factor. Unfortunately I haven't been able to work out how to avoid the 4am BG drop - I don't care about the BG figure itself but I'd rather not have the nightmares and sweats.

As for side dishes (and leaving aside green veg and mushrooms) - I discovered last year I don't have a problem with pulses/legumes. I get a small BG rise and back to normal within two hours. I do rinse all the starch off the outside, which might help a bit, and I never now use the water that beans have cooked in. Still have the same unacceptable rise with potato and anything flour based.
 

What finger prick method have you used?
 
Yes to the retinopathy test, no to everything else.
Rapidly improving BG can kick off background retinopathy.
I had BR picked up on my first eye scan post diagnosis when I was in remission.
Last 2 have come back all clear so now I'm pushed out to every 2 years.
 
Hi ronan that was interesting to read about retinopathy and improving BG can kick off background didnt realise that at all This is why this site so good for learning new stuff Kerp it coming........
