Lot of really mediocre advice, from those poor souls lacking the sufficient level of autism to read medical research, like an adult
As has been previously said, fasting glucose is a really poor diagnostic tool for (pre)diabetes. Hba1c is better. However, you can also perform an oral glucose tolerance test, at home, for almost zero cost. Instructions are linked here
https://www.homerton.nhs.uk/the-glucose-tolerance-test-ogtt-protocol/ . Their table is using mmol/L for results, but in burger units, 140-200 would be the prediabetic range, 2 hours after the bolus administration of glucose
Assuming that you are prediabetic, it's incredibly treatable. As is full blown type 2 diabetes. All either of these conditions are, at the core, is a resistance to insulin. All you need to do is help your body become more sensitive to insulin. From my understanding, t2 diabetes is "officially" incurable, but that's retarded. It's akin to saying that obesity is impossible to fix, because, well, maybe one day, you might get fat again.
This can be done by a combination of lifestyle, diet, and medical intervention.
In terms of diet, all you need to worry about is reducing glycemic load. You don't have to do goofy meme diets like Paleo, or epilepsy treatments like Keto, you just have to be willing to act like an adult. You might reduce carbohydrates a bit, but the main focus should be on making sure that the carbohydrates that you do have digest more slowly. This will generally mean less refined sugar, especially shit like soda and candy. This will generally mean more fiber. It may mean more fat, although, not if that would cause you to gain weight. Maybe around 10-20 grams with each meal, to help slow digestion a bit. Yes, I said grams, because I'm an adult, which means I weigh and record everything that I eat. Try your best to avoid eating for at least 2-3 hours before bed, especially large amounts of simple carbs. Don't worry about artificial sweeteners, all of the people who are afraid of them just have cognitive decline, as a result of insulin resistance within the brain. Can you find a few papers here and there saying that this or that artificial sweetener might potentially have this or that negative effect? Sure. You can find thousands of papers saying that real sugar is a million times worse. If you currently drink soda, and switching to diet soda make for an easier transition, do it. It will pay dividends in terms of health.
The first medical intervention to look at is metformin. You can go ask your doctor for it, like a pussy, or you can act like a grown up and find a source on your own. Start with 1 500 mg extended release tablet each day, taken with dinner. You might experience some mild indigestion, maybe a bit of diarrhea. It should go away after a few days, maybe a week. This is the worst side effect that 99.999% of people will have from metformin. After you've had a week or two without any GI issues, you can start taking a second 500 mg tablet, with breakfast. You could potentially repeat this, adding an additional 500 mg with lunch. There are some other medications/supplements which you could add on. But if you're hitting even the lowest hanging of fruits with diet and lifestyle, it's probably not needed, unless your genetics are well and truly fucked. Once the insulin resistance is resolved, just stop taking metformin.
As effective as metformin is at reducing insulin resistance, what's even more effective is simply taking a ten minute walk after each meal. You can't go outside to walk, without being harassed by feral niggers? Just pace in your room. It doesn't have to be fast, you don't need to work up a sweat. Just walk at a moderate pace. Real exercise is great, and there's a million other reasons why it's probably a good idea, but if your main concern is insulin resistance, then this is where the money is at.
It's that fucking easy. Do this basic shit for a few months, odds are, prediabetes is gone.
(I don't actually have beef with keto diets. I've done them, I like them. The main reason to go that way would be if it reduces anxiety, or helps you think more clearly. I wouldn't recomend it for most people, because of the effect it can have on Sex Hormone Binding Globulin and lipids. I know not everyone gets fucked up lipids or SHBG from it, but you don't know unless you get bloodwork done. I also understand the arguments about how lipids don't actually matter in the context of a keto diet. The argument is akin to saying that it doesn't matter if your clothes are soaked in gasoline, because you won't burst into flames unless there's a spark. That might kind of be true, but it's the argument of an absolute madman)
