Cut out pure sugar as much as possible and probably also carbs as much as possible since they turn into sugar.

Chesmist here, not a doctor. Dont take that unless you have no more options.. There is a long list of foods ( have to be the real food though) that lowers glucose levels in your blood. Go for the healthy diet before put any of those in your body. See the list on the interwebs and center in adding some of those in your diet before you take any more chemicals. And if the goal is to loose wheigth, taking meth would be more healthy than take semaglutide.

There are many different "tools" one can use to accomplish this.

Some people have tried a carnivore diet with success, but sometimes long-term adherence may cause paradoxical reactions (myself, included). Carnivore seems to work by directly inhibiting insulin response and reduction of linoleic acid (see below), but with ratio of protein:fat that's too high, metabolism can slow due to 1) lack of energy, 2) too much reliance on gluconeogenesis, and 3) high protein's direct effect on slowing metabolism because of the amount of thyroid hormone required to process it - in addition to the fact that most people are undiagnosed hypothyroid anyway if looking at classic signs as opposed to blood markers.

Lowering protein and increasing energy intake (moreso if carbs/fats are separated as to not activate the Randle Cycle) can help to speed up metabolic rate. High sugars and low protein are both known to increase FGF21 which increases metabolic rate. This is part of your "calorie out" for those that obsess over CICO.

PUFA, particularly oxidized linoleic acid, has been known for DECADES to directly cause diabetes, and yet, we promote it for its "cholesterol lowering benefits". These are especially high in all vegetable/seed oils, even olive oil (because most are spiked anyway). If you pull something off the shelf at your local grocery and it has any fat in it at all, it will be nearly guaranteed to be fat from a vegetable/seed oil. Pork and chicken fat are even worse than those oils because they contain higher percentages of linoleic acid. Sugars are not the cause of diabetes. Look at the fruitarians - although unhealthy in the long-term, they don't have diabetes. The cause is that something (PUFA, especially) is blocking your body's ability to utilize it, hence why it continues to elevate.

This is actually a very interesting and informative read with regard to the Randle Cycle (macronutrient swampland, as she calls it). You will also see an amazing diet of essentially pure carbohydrates that has been known to work very well for over 100 years. Somehow, this knowledge has been "lost".

If you fix your metabolism, you will fix your glucose issues. I would recommend not stressing about cholesterol or what your doctor may say. Ultimately, everything is your decisions, not theirs.

The links inside here also have some interesting "diets" you could try until you learn more about metabolism.
