This was me, is me. I had to start a no grain diet to get my blood sugar down. Between that and exercise, I have avoided, so far, having to take meds for diabetes.

I am diabetic, but my average blood sugar is in the normal range without medication. If I eat wrong or get lazy, I have problems

Yeah, they really are. The only valid medical reason to ever use the keto diet is if you have severe epilepsy, and that is an intervention that is only supposed to be done short term, and under close medical supervision.

At best keto as a general diet generally shows to result in rapid weight loss for only about a year at most, before it plateaus. Odds are any results that come from it are only because the person dropped a few high caloric foods. If your plate is usually full of meat and Mac and Cheese, and you replace that with more meat and, I dunno, buttered veggies, then you're probably eating less calories overall. That would explain the plateau too, because being in a calorie deficit is a state of starvation, and even unconsciously we have a tendency to seek out ways to calm our cravings. That's why plant-based diets are the most effective and consistent for weight loss, because they are naturally lower in overall calories while also providing foods that are known to be satiating.

Obesity in and of itself is the primary driver of type 2 diabetes, and overconsumption of fats - especially saturated fats - are drivers of insulin resistance. So while keto might provide short term symptom relief since your body doesn't have to process sugars, it is about the worst thing you could do for yourself to treat the illness, because you are making the underlying cause worse in the long run, as well as driving progression of cardiovascular disease. Effective, sustainable treatment of type 2 diabetes has to involve, first most chiefly, overall weight loss; but you also need to lower total fat intake, as well as replacing the harmful fats like butter, lard, coconut and palm oils, as well as meat and dairy, with good fats like canola and olive oil, and whole food sources of good fats like nuts and seeds, and avocado.

You can find a solid, real scientifically backed program for both type 2 and type 1 diabetes treatment here.

I want it to be understood, I am not interested in internet arguments when it comes to this subject matter. This is not banal identity politics. This is life and death. I have seen too many loved ones die and all from poor lifestyle habits, including type 2 diabetes. It doesn't need to fucking happen, and I am sick of people flippantly advocating for something that is quite literally the opposite of everything that nutritional science has found to be truly effective. It is grossly irresponsible. Keto is just one more re-branding of a long history of failed anti-carb diets. They never have worked, they never will work, and the only job they need to do is sow enough doubt in people's minds to get them to keep eating all of the things that are killing them. It is the tobacco industry playbook plain and simple.
