Type 1’s, how many carbs do you eat/day and what is your A1c?

I have been doing low carb (30 grams/day) for 5 years and am thinking of increasing the amount of carbs I eat. My A1c’s have been in the 5’s since doing low carb but I don’t like meat that much and would like to see if I could increase carbs and still have good control. I’m curious if good control can happen with increased total carbs per day.

My A1c is 5.7 and I eat about 80 carbs (plus more to cover lows) per day.

I eat betw 175 and 200 grams of carbs per day and A1c has fluctuated in range of 5.9 to 6.3. Most recent was 6.2.

I eat about 130-150 carbs a day and my A1c has ranged from 5.30 to 6.0 over the past 5 years.

I eat about 30 grams of net carbs a day and the A1C I just got back today is 6.4 ( :heart_eyes::heart_eyes::heart_eyes:) which is the lowest A1C I’ve ever had. Before going low carb my A1C was in the 7’s or 8’s consistently. I don’t see myself as typical as far as being able control my diabetes however because I think a lot of diabetics who work as hard as I do to maintain a decent A1C can have spectacular results like you seem to have.

I think higher carb diets and good A1C’s are absolutely possible just harder to maintain BG wise but low carb diets can also be hard to stick to so it’s a trade off either way.

I eat about 60-120 carbs a day and the last A1C was 5.2, thanks to CGM. A1C was around 5.6 with the same diet, while using test strips. I think it is not really how many carbs you eat, but how you manage them. I like to stick to high carb meals that I’m familiar with. I know when and how much insulin I would need with them and I know how my body would react. The result is a relatively flat line with a spike up to 150 at most. Trying new foods might lead to higher numbers before I learn how to manage them, but I take it as a part of a learning process and don’t worry too much.


80 to 90 carbs/day, 6.9-7.1 a1c

I typically average 90-130 carbs per day. My latest a1c was 6.6, which is right where my endo wants it to stay. They said there is greater cardiovascular damage at below a 5 a1c.

My last A1C was 5.6, at that point I was eating +/- 100 grams/d carbs.

Since August, I eat < 15 grams of carbs per day, and anticipate my next A1C will be between 4.6-5.0

100-150g per day. A1c - 6.1. I’m happy there.

I eat ~100g per day, A1C 5.7

Probably around 180g a day, last A1C was 5.3

I have no idea how many carbs I eat a day…maybe 120? I refuse to monitor or restrict my life that drastically. My A1C is 7.5

WOW. Y’all. I try to eat 45 carbs/meal. It usually ends up being 30-40 and my endo and I are quite happy with my A1C at 7-7.5. When it goes any lower I have multiple reactions. But then again I am older. LOL

I use to be 6.3, since I went on the Medtronic 670G in June now I am 7.1 and I do not feel good. My carbs range from 50 to 80 a day.

I went back to the Animas pump last week, I hope this will bring my numbers down where they should be. My blood sugars are so much better I test 8 to 10 times a day.

A1c ranges from 5.6 (last one,) to 5.8.
I eat 60 to 260 a day. Just depends.
Knowing how to bolus, prebolus, aggressively correct, etc. makes the difference to me.


Oh yeah, and having Fiasp allowed me to eat more carbs, and have a MUCH shorter prebolus time. It really made a big difference for me personally.

Lately very little carbs and I’ve been trying to follow Bernstein as much of the time as I can. The predictability is what amazes me about it. My basal rates/doses are the same almost every single day, and I’m not constantly monitoring my CGM and making adjustments to stay in range. It’s far, far less work and feels more like I just have a food allergy and have to take medication every time I eat rather than like having type 1 diabetes. It’s hard to describe, but I feel very “stable” during the day as well. When I am eating carbs, even if I get the bolusing right (which is more coincidence than skill), I always feel like I am going up or going down and it’s not a pleasant feeling. Lately I just feel very stable, again as if I don’t even have type 1. Even if I check my Libre and I’m in the 3s it’s such a mild low and so easy to treat with just a glucose tablet or 2. It’s really motivating because, again, no matter how good I am at sugar surfing, there is no comparison to how easy this is and how good it feels mentally and physically.


Congrats, Scott_Eric! We follow the same Dr.B protocol (for my son), mostly… and yeah, it’s so much more predictable, stable, and less stress… and we very rarely need to make corrections… but when we do (usually due to cold/flu or growth spurts) they are typically minor corrections… rare for highs over 130 or lows less than 65. He is a growing boy, so he usually eats around 50-60 carbs per day, and plenty of protein. My boy’s A1c ranges between 4.8 - 5.1%

The same protocol works well for Type 2’s also
If that is allowed in this discussion
