There are few controls on procedures performed in medical offices. Be very cautious when submitting to such things. Most stuff done in hospitals or surgical centers are covered by regulations, inspections, and certifications. Ask about them when you are having procedures done and see what agencies certify or inspect them. In many doctor's offices, the only regulators are the doc's malpractice insurance providers.

I've personally been eating a high complex carbohydrate diet for most of my life, especially since 1974. My current diet consists of oats, pinto beans, white rice, a little bit of organic cane sugar, and plenty of fresh fruit. I'm currently growing 9 fruit trees in the limited space available, apricots, nectarines, plums, cherries, and pineapple guava. I don't eat any fatty foods, and I never listen to any advice / "research" blathered out by chemical corporation shills. Obesity, and therefore diabetes, is the #1 epidemic in the United States, the primary cause being pharma chemical corporation research and their toxic poisonous drugs.. Diabetes is nearly a 100% precursor (requirement) to getting dementia.
I think that one of the problems is that we are given such diverse information about what is good for our health. Some of the doctors who write health books advocate a low carb, high fat diet and claim it helps diabetics, and other doctors say just the opposite, that the meats and animal fats are bad for diabetes, and you should eat a plant based diet, and they claim the best results of treating diabetes. In the meantime, the doctors seem to say just live your life, stay away from lots of sugary foods, and take your medications as needed and you will be fine. I do not have diabetes, but I DO want to take the best care of my health as I can, and I am always reading health books, and I have swapped back and forth between the LCHF and the WFPB ways of eating. Right now, I am reading Dr. Greger’s books again, and following a mostly WFPB eating plan. It seems like the one thing that all of the eating plans agree in is that we need to eat more vegetables and greens, so that is always a good addition to whatever WOE a person is following.
I will just jump in here to say that there really is no one size fits all when it comes to diabetes. The best way for an individual to find if a food has a negative impact on their glucose levels is to "eat to your meter." Get yourself a glucose meter and learn how to use it. Try a meal with a bit of potato or rice, then check your glucose level one hour after eating. You will easily see whether you can tolerate a bit of starchy foods by investigating for yourself.
And I would recommend checking in the morning if you has a heavy carb meal in the evening to see how it affects things over a longer period.
I will disagree for one reason; many diabetics have what is called "dawn phenomenon" where their glucose is always high in the morning (hyperglycemia). It doesn't seem to matter whether they have a carb-laden meal the night before. One thing that does impact post-prandial (after eating) glucose is whether the individual is on diabetes medications or insulin. Taking medications allows patients to eat fairly normally, including carbs in moderation.
For anyone with Type II Diabetes, I can highly recommend Dr. Jason Fung's The Diabetes Code. You may find, like me, that doctors' explanations of diabetes don't exactly make sense, nor do they give you any real tools for dealing with it. The Diabetes Code has an explanation of diabetes that I'd not run into (I'm actually pre-diabetic), with great explanations of what's really going on (and why what's recommended doesn't work and/or are the opposite of what one ought to do), and ways to help you though it. The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally https://www.amazon.com/gp/product/B0795BLS8D/ref=ppx_yo_dt_b_d_asin_title_351_o00?ie=UTF8&psc=1 I'm doing this for maybe a month, and it's already made a difference. It's $9.99 for the Kindle version. Couldn't hurt, and could really help.
For many doc referrals in my life, I got them from friends....and then eventually got into Integratve Medicine and found and heard about those docs here in So. Cal....alternative medicine has moved a lot to West Coast.... And a lot of doc finds have been hit and miss and good outcomes for you on what docs have recommended.... Starting in the 80's I woke up to pharma drugs....and the damage we can get from them....
