Yes -- and the single most important thing to do to reverse a prediabetic condition and make insulin resistance go away is to lose weight, preferably through a combination of diet and exercise.

The diet part doesn't require a special "diabetic diet," however. The very best diet for this situation is the quintessential approach to eating that everyone should follow: a plant-based, whole-grain, lean-protein, healthy-fat diet. This diet has been shown to protect against major health problems including heart disease, cancer, arthritis, and Alzheimer's -- conditions for which someone with a history of diabetes is at increased risk.

Making a dietary about-face requires a commitment to changing one's lifestyle. Specifically:

Before you eat a carb, consider what type it is. Choose whole-grains over processed types. Eat whole fruit rather than juice. Avoid white flour and white sugar, which are found in many processed foods.

Boost the total amount of fiber you consume, especially soluble fiber. The average American eats 15 grams per day -- but adults need 45 grams per day. Of that total, half (20 to 25 grams) should be soluble fibers, the sticky-gummy fibers found in oatmeal, oat bran, legumes, barley, peas, and citrus fruits. Soluble fibers bind with cholesterol in the digestive system to help eliminate it, they lower lipids, and they help keep blood sugar in check. (Insoluble fibers include wheat, wheat bran, rye, and rice.)

To get 45 grams a day, you might start with a bowl of whole-grain cereal, such as steel-cut oats; add ground flaxseed and chopped nuts and a serving of fruit. Throughout the day, choose whole grains, beans, or whole-grain pasta. Substitute brown rice or barley for white rice.

Choose healthy fats for eating and cooking. Good choices include nuts, avocadoes, seeds, extra-virgin olive oil, and canola oil.

Add cinnamon to your diet. This spice helps to decrease insulin resistance -- and most people enjoy the taste. Use it to flavor oatmeal, sweet potatoes, coffee, or tea.

Choose protein that's lean, and eat less animal protein overall. Best choices: cold-water fish, whole soybeans, and any variety of legume, such as black beans, red beans, lentils, and edamame.

Take a good daily multivitamin. Choose one that provides 100 percent of the recommended daily value for most major vitamins and minerals. Certain microminerals, such as zinc and magnesium, are critical to blood sugar regulation. For most folks over 50 years of age, however, iron should not be included.

Check that your supplement contains the USP (United States Pharmacopoeia) seal of approval. It's possible to purchase an annual subscription to if you'd like to be able to review independent analyses of select supplements and vitamins.

I actually live on a high-protein/low fat/low carb diet because I need the protein for my muscles and I've found that iron pills don't work for me (of course, I also have Fibromyalgia). Agave syrup is on the good end of the glycemic index, so I use that for my tea & coffee. When I make oatmeal raisin cookies, I use the exact same amount of Polaner Allfruit instead of sugar as it counts as a fruit serving.

I am a 72 year old diabetic. My life and disease have been altered by reading three books: Gary Taubes Good Calories, Bad Calories, Bernsteins Diabetic Souution and Taubes Why We Are Fat"¦.

Following the advice of these two authors I have lost 30 lbs and lowered my fast acting insulin dosage from 190 units to less than 5 units per day. For a diabetic ALL carbohydrates are bad! Some people argue that Taubes is not a medical professional, but Bernstein is both a diabetic and a doctor, who runs a diabetic clinic. Coming from different perspectives, they agree.

When I read the recipes recommended for diabetics and how much carb is in them I laugh. This article recommends one kind of carbohydrate over another. Any carbohydrate is bad for a diabetic!

Wow, I'm really learning a lot here! Keep up the good work. One thing I'd like to know more of are natural remedies for diabetes. Do any of them really work or am I stuck taking insulin for the rest of my life? Any help would be greatly appreciated. Thanks and best of luck.

Diabetes can be reversed by natural home remedies, despite what some people might say. As a 30-year diabetes sufferer, I know how frustrating it can be to find answers. Fortunately, my diabetes is nowhere near what it once was. Just wanted to share a something that helped me out a lot when I was struggling to get better:

Best of luck to everyone!

When I was diagnosed with diabetes on Feb 26, 2016, my blood sugar was 385 and my A1C was 10.8%! My dad had been diagnosed a year prior and in doing his own research he realized that what is typically "prescribed" the medical community, is just about the opposite of what really works. Whether it's intentional or not (and I really want to believe it's not), it would appear to be designed to insure that the pharmaceutical companies are well kept. Please understand, I am NOT making accusations, I merely state what things look like. And we all know that looking one way and being that same way, can often be two different things.

All that said, while doing his research, he ran across a "book" (more like a booklet) that roused his curiosity. It was called 'Smart Blood Sugar' written by Marlene Merritt of Austin, Texas. She has a masters in nutrition and is licensed by the state of Texas as a doctor in Chinese Medicine. She promotes a diet of LOW carbs (60g/day or less), high fat and high protein. Now before you have a cow about the high fat and protein, I don't have the book right in front of me to be able to tell you what the "qualifiers" were/are for this diet. And understand, when I say diet, I don't mean a diet as in you're trying to lose weight. I mean diet as in a LIFESTYLE CHANGE IN YOUR DIET! BIG difference! One thing she points out in the book is how most people think that diabetes is genetic. Apparently not... there might be a propensity for the development of diabetes (my thought), but she points out that genes aren't the only thing that we inherit from our family. We also "inherit" our eating habits . . .

By following her VERY simple instructions, in ONE AND A HALF MONTHS .... my blood sugar was down to NORMAL, as in, normal for someone who doesn't have diabetes. In THREE months, my A1C was down to 6.2%. And it would have been slightly lower had it not been for the fact that I ended up taking steroids for my breathing due to a chronic lung disease. Steroids elevate your blood sugar. My doctor was stunned. In almost 30 yrs of practicing, he couldn't remember another patient having diabetic numbers as high as mine be able to reduce them in such a short time frame WITHOUT the use of medication! My dad had the same result after using her suggestions. The book was about $30, kind of high, but WELL WORTH the information contained inside! I hope the following links will go through... I'm putting 3 links below, if they fail to go through, the most important one is for the book. You can Google the book and find the home page for Merritt Wellness Center that way. The other two links are for two articles that she has written and have been published. I'm guessing that you can also Google their titles and find them on her website that way. Good luck to all of you!
