I also have higher fbs, I was diagnosed Aug 2019 with an A1C of 11.9 from June 2019 (my GP failed to call me to let me know I was now diabetic). By Sept 2019 I was down to 8.9, last year in March 2020 I was 6.5 A1C and sugar levels have come down since, I wear a Libre and according to it, my A1C is around 5.5. I am off all diabetic medications since May 28th 2020, I was only on them for 9 months till my sugar levels improved with dietary changes, I was getting severe hypos so was taken off of them.

I have not found anything to make my fbs lower. But what I have figured out is if I fast too long my sugar levels go up. In my case fasting is not an option, and many diabetics like I believed fasting in the morning by skipping breakfast would help, but it did not.

There are a few reason our fbs are high and this has to do with how our human bodies are programmed even in non diabetics. It has to do with when we wake up, or just before we are waking up, our body produces hormones such as Cortisol, and many others, but our pancreas as diabetics may not produce enough insulin to counteract this normal everyday effect of our bodies preparing us for the day ahead

I also found that fasting to try and bring sugar levels down makes things worse, as by then your liver senses that your cells are not getting enough sugar, so it thinks it needs to add sugar to nourish your cells by releasing the stored sugar in our liver into the bloodstream, but this makes things worse for diabetics, as now we have even more sugar in bloodstream that we need to bring down. Insulin is what carries the sugar from the bloodstream into your cells, so as diabetics our insulin production is either insufficient, or our bodies have become resistant to our own insulin, so the sugar stays in the blood and our cells do not get the sugar they need to function, hence the many complications for diabetic if our cells cannot play their part.

For people on insulin your doctor should be made aware of this and adjust or add insulin to your regimen. For those of us off medications, well not much works. For myself I eat very low Carbs breakfast as in 4 to 7 Carbs, in my case this works for me, decreases my morning sugar levels and makes it easier to manage the rest of the day. But what works for one person may not for others as our metabolisms are all different and our diabetes progresses at different rates.

Cinuim and eggs and water

I fast from morning until 2pm only drinking water and hot tea, 9am a small fruit and 11:30am another small fruit and 2pm a light lunch of tuna, a large garden salad and 8 ozs hot tea, 5pm a small fruit and 6:30pm a light dinner with water. Have a blessed day and drink 48 ozs or more water. I don't eat rice, pasta or bread. More leafy veggies and sweet potatoes. Have a blessed day! 😁

Getting your weight down is very important
I lost 6 1/2 stone and have been off medication for quite a few years. At worse my hba1c was 10.8 when first diagnosed
My last one was 6.3. It has been lower 5.7. I put on 2 stone and am getting it off again.

Fasting works for me and I've lost weight also my A1C number is less now. My doctor is pleased and I'm not taking meds for diabetes. Fasting isn't for all but it works for me. I've stopped eating fried eggs, cheese but eat baked meats especially fish, salmon also eat tuna and sardines which gave me good cholesterol numbers. My blood pressure numbers are great most days and I take my medication twice a week or as needed praise God 💕🙏. I drink 4-5 bottles of water daily and often walk 12,000 steps 5 days a week or more. Do what works for you.
God bless us all.
