Eating for insulin resistance, and the other things that move it If you've just been told you have insulin resistance, food is usually the first thing you want to change. The CDC and the NIH agree it matters, and both list other changes right next to it. By **GlucoseBench editorial team**Updated September 27, 2026 ![Eating for insulin resistance, and the other things that move it](https://glucosebench.com/img/guia-insulin-resistance-diet-640.webp) Short answer Neither the CDC nor the NIH's diabetes institute (NIDDK) prescribes a named "insulin resistance diet." The CDC's advice is a balanced diet "with non-starchy vegetables, fruits, whole grains and lean proteins," which lowers blood sugar and, with it, how much insulin your pancreas has to release. Food sits next to three other changes the two agencies name: physical activity, weight loss if you have overweight, and medicine such as metformin when a doctor prescribes it. In the NIH-funded Diabetes Prevention Program, losing 5% to 7% of starting weight helped people at high risk lower their chance of type 2 diabetes. ## What the CDC puts on the plate The CDC's page on insulin resistance keeps the food advice to a single sentence: "Eating a balanced diet with non-starchy vegetables, fruits, whole grains and lean proteins helps to reduce your blood sugar." The logic follows from how the problem works. Less sugar coming in means less insulin needed, and the CDC says that drop in insulin helps turn the resistance around. The NIDDK's version is shorter still: "consuming healthy foods and drinks." No carb count, no banned list, no fasting schedule. That's less exciting than a branded diet, and it's the honest version. For the details, the CDC's carb-counting advice for people with diabetes suggests working with your doctor or a registered dietitian, and our prediabetes diet guide covers the CDC's plate, which comes from its advice for people with diabetes. ## What changes insulin resistance, one by one Change What the source says Source Physical activity "Physical activity makes you more sensitive to insulin." The CDC says not to wait for a diagnosis to start moving more. CDC Weight loss, if you have overweight or obesity A way to "relieve strain on your body and increase your insulin sensitivity." In the Diabetes Prevention Program, losing 5% to 7% of starting weight helped people at high risk. CDC; NIDDK Food A balanced diet with non-starchy vegetables, fruits, whole grains and lean proteins. CDC Sleep and stress The CDC adds "managing stress, and getting enough sleep"; the NIDDK counts enough sleep as part of healthy living. CDC; NIDDK Medicine Metformin may be prescribed to help manage blood glucose and prevent type 2 diabetes. In some cases, weight-loss medicines or metabolic and bariatric surgery can help. NIDDK Sources: CDC, "About Insulin Resistance and Type 2 Diabetes" (May 15, 2024), and NIDDK, "Insulin Resistance & Prediabetes" (last reviewed March 2025), both read on September 27, 2026. ## Where medication comes in Diet and exercise get the attention, but the NIDDK is plain that a doctor may add a prescription: "health care professionals may also prescribe medicines such as metformin to help you manage your blood glucose levels and to prevent type 2 diabetes." In the Diabetes Prevention Program, metformin also delayed type 2 diabetes, and it "worked best for women with a history of gestational diabetes, younger adults, and people with obesity." The long view is what we find most convincing. The NIDDK reports that the follow-up study "has shown that people can prevent or delay type 2 diabetes for at least 15 years with lifestyle changes or metformin." Keep that in mind when you read the supplement table below, because NCCIH itself calls the supplement evidence weak. Whether metformin fits you is your doctor's call, and the NIDDK suggests asking directly. ## Supplements sold for "insulin sensitivity": what NCCIH found Several labels on this site pitch insulin sensitivity. These are the ingredients behind that pitch, with what the NIH's complementary health center (NCCIH) reports and who was actually studied. Its overall verdict: "For a few dietary supplements, there is weak evidence of a possible benefit." Ingredient On labels here What NCCIH reports Who was studied Caveat NCCIH gives Chromium 9 products; from 0.7 mcg to 1 mg per serving where an amount is given A 2022 review of 16 studies: supplements "may help improve" HbA1c, fasting blood glucose and insulin resistance People with type 2 diabetes "There have been a few reports of kidney damage, liver damage, muscular problems, and skin reactions following large doses." Insufend holds 1 mg per capsule. Berberine 3 products (Glyco Pulse, Gluco Extend, BloodArmor), none with an amount A 2021 review of 46 studies: may help lower blood glucose and reduce insulin resistance People with type 2 diabetes, mostly Chinese patients "Some of the studies were of poor quality," and berberine "may interact with some medicines." Cinnamon 7 products, none with an amount A 2019 review of 16 studies: helped reduce fasting blood glucose and insulin resistance People with prediabetes and type 2 diabetes On herbal supplements as a group: "We don't have reliable evidence that any herbal supplements can help to control diabetes or its complications." Magnesium 2 products (125 mg and 20 mg per daily serving) A 2021 review of 13 studies: "may improve insulin sensitivity" People at high risk of diabetes For people with diabetes, a 2022 review's authors said "the research so far is insufficient for providing any clinical guidelines." Source: NCCIH, "Diabetes and Dietary Supplements: What You Need To Know" (last updated November 2023), read on September 27, 2026. NCCIH describes the ingredient, not any product sold here. Label counts come from our reviews and ingredient guides. ## Before you add a capsule ### Who the research is about Mostly people who already have type 2 diabetes. If your diagnosis is insulin resistance or prediabetes, most of that research wasn't done on someone in your position. ### Diabetes medicine On metformin, insulin or another diabetes drug? Talk to your doctor before adding anything sold for blood sugar. NCCIH warns that herbal supplements used with conventional diabetes drugs "can cause unwanted side effects." ### Kidneys NCCIH says kidney disease has been linked to some dietary supplements, a particular concern because diabetes is the leading cause of kidney disease. ### The short list Food, movement, weight and, if your doctor thinks it's time, a prescription. That's the list both agencies give, and a supplement isn't on it. ## Frequently asked questions **What is the best diet for insulin resistance?** The CDC doesn't name one. It recommends a balanced diet built on non-starchy vegetables, fruits, whole grains and lean proteins, which lowers blood sugar and the insulin needed to handle it. **How do you improve insulin sensitivity?** The CDC names physical activity first, then weight loss if you have overweight or obesity, a balanced diet, managing stress and getting enough sleep. **Can you lose weight with insulin resistance?** The CDC and NIDDK both count weight loss as part of the answer. In the Diabetes Prevention Program, losing 5% to 7% of starting weight helped people at high risk; your health care team can tell you what a healthy weight is for you. **What medication is used for insulin resistance?** The NIDDK names metformin, which a doctor may prescribe alongside healthy living and weight management. In some cases, weight-loss medicines or metabolic and bariatric surgery are options. Each of those is your doctor's decision. **Do supplements help insulin resistance?** NCCIH says some studies suggest chromium, cinnamon or berberine "might help with blood sugar control," calls that weak evidence with no clear conclusions, and the studies were mostly in people with type 2 diabetes. It also says "It's very important not to replace medical treatment for diabetes with an unproven health product or practice." **Can insulin resistance go away?** The CDC's answer is encouraging: it can be turned around by making your cells more sensitive to insulin, mainly through activity, weight loss and food. Ask your doctor how you'll track progress, since the NIDDK says a direct insulin resistance test is mostly a research tool. ## Related pages Blood sugar basics ### [Insulin resistance: the condition a symptom checklist can't find](https://glucosebench.com/insulin-resistance) Insulin resistance is "a condition in which your body doesn't respond to insulin the way it should," according to the NIH's diabetes institute (NIDDK).
