I eat less than 50 carbs a day, diagnosed 4 months ago and still stabilising (no meds) recent fasting bloods 6.5 ish, and daily averages 6.9 but yesterday and today in the high 7's -mid 8's, along with the jitters and mood swings.
I can only tell you my experiences. I was type 2 before the progression to LADA, which I am now.
When I was type 2 (as well as now) I had to stay under 20 c per day. No grains, starchy veggies, sugars, juice etc. I tolerated NO carbs at bf. I would spike much higher at bf eating the same food than later in the day. I would walk a slow to moderate pace after meals for about 15 min when I could. This helped a LOT! I doesn't have to be strenuous or brisk by any means. Just constant movement. Raising your heart rate raises adrenaline and cortisol which raises bg so in the morning just make it relaxing.
I have been 20c or less per day for over 25 years when I started Atkins and never looked back all through my D progression. Carbs make me feel like junk. Achy, exhausted, etc. Now as a LADA I found myself landing on the exact same diet it have eaten for years.
Not all carbs are equal. You may be able to eat more than me but there are the 'danger ' ones like all things made with flours or grains including rice. Starchy root veggies, legumes, sweet fruits can all create a large spike.
Above ground veggies tend to not create such a spike so you might be able to eat more of those.
What's left?
Proteins of course but moderating those is important too. 58% of protein can turn to bg
Above ground veggies. I like using large lettuce leaves instead of breadfor sandwich fillings. I use a spoon for peanut butter or melted cheese.
Fats that I use regularly are avocado ( very satisfying, as is a piece of cheese) mayo, olive oil, pecans, macadamia nuts and olives.
I don't eat fruit but berries are best and eaten with some fat.
I don't gob fat but rather just normal amounts. I don't eat chicken skins, fatty sausage ( plenty of good chicken sausage) lots of butter or animal fats. Animal fats tend to raise me higher and keep me higher longer. I prefer plant fats. Fats still make up 75-80%!of my diet. 15-17% protein and about 5 carbs, mostly on avocado, nuts and lettuce. Some asparagus , scallions but broccoli sends me sky high, love it though.
I use portion control. I don't need nearly the amount of food I'd love to eat.
You might just need to switch some of your carbs for slower digesting ones to tame the beast.
8's would have me jittery. In fact the jitters is my indicator that I'm going up. For me, I can take insulin. You can take a walk or not eat that food that is making you go there. If weather doesn't permit I would walk up some stairs for a few minutes or dona few light push ups on the counter. Typically that was enough. Again, strenuous can raise you first.
It's such a challenge to figure out what to eat that I just keep everything simple. It's not boring for me as I enjoy all my food. It can be a bit monotonous but it's 'just food'
Bf. Thin slice turkey on lettuce with mustard and mayo
Lunch. 2 oz protein, 2 oz avocado and some rW chopped veg like scallion, radish, celery
Dinner Same as lunch
I have a large variety of precooked proteins and choose which one I want. Then I add a few veg, avocado and either mayo or olive oil.
Hope that helps. You'll figure it out. It takes time and trial and error. Keep testing to eliminate spiky foods and find foods that work great. Avocado at all meals keeps any potential spike lower and slower for me. Very diabetic friendly and a perfect fat source. But this again is just my experience through oodles of testing
