I didn't mean 'requires no insulin at all,' I know T1D requires some insulin to regulate blood sugar and to perform other functions in the body.

What I meant was that, for example in the OP article, a 60g bolus of carbs brings blood sugar from the bottom of healthy range all the way to the top of the healthy range in one go.

It just seems like an unnecessarily large and (for most) difficult to control jump in blood sugar. A lower-carb diet, say under 50g total carbs per day, should reduce blood sugar swings and increase their controllability, letting patients be in the healthy range of blood sugar for a higher percentage of the day.

In general yes, but again, unfortunately there are a lot of complicating factors. I can eat meals with 60g carb content and have my blood sugar levels barely move at all and I can also have, for instance, a beer with 15-20g of carbs that causes a 6 to 8 point rise. The trickiest part for me is finding the right balance between not having a massive meal peak, but also having stable levels in between meals. What works best for me personally is eating 'slow' meals i.e. meals that have a low glycemic index. These don't necessarily have to be low on carbs, but should be high in fiber, protein and unsaturated fats, which again is also very personal since each of our guts responds differently resulting in different rates of blood sugar production for different meals.

The problem with just eating low carb meals in my case is generally that it offsets the balance in between meals, i.e. I'll start seeing a consistent rise that might be something like 0.5-1 point per hour which eventually adds up. Of course you could increase your baseline insulin to offset that again, but it requires a lot of experimentation to get that balance right.

I do occasionally switch out my somewhat carb heavy lunch for a lighter low carb meal if I'm really busy and don't have time to go for a walk for instance. Generally that does work just fine to keep the initial rise low, but requires another 2 units of insulin about 2.5 hours after the meal because my blood sugar level keeps rising.

So in short, yes moderating your carb intake and especially ensuring your meals are slow are ways to make managing your blood sugar levels easier, but in my opinion it still requires experimentation to find out what works or does not work for you personally.

Type 1 diabetic as well here - I do this and I can confirm that I have much better control over my HB1C (average blood sugar reading) since I eat mostly a keto and plant based healthy diet (composed of minimally processed foods). One issue that I have though deals with hypoglycemia (low-blood sugar levels) since type 1 diabetics don't just require immediate insulin after meals - they require long-term acting insulin which works throughout the day. I've had multiple cases where I lost consciousness and woke up either in an ambulance or in a hospital feeling like someone hit me with a truck and having no recollection of how I got there. There is no 'magic' in managing type 1 diabetes unfortunately. The issue with us is that our blood sugar can swing in both directions - with the lower swing possibly resulting in death.
