Insulin sensitivity and diabetes -
A research team led by Drs. Barbara Kahn and Mark Herman of Harvard Medical School and Beth Israel Deaconess Medical Center set out to investigate. Their work was funded primarily by NIH's National Institute of Diabetes and Digestive and Kidney Diseases NIDDK. It appeared in the advance online edition of Nature on April 1, The team began with 2 types of transgenic mice in which insulin resistance and obesity don't correlate.
The mice have alterations in GLUT4, the protein primarily responsible for transporting glucose into muscle and fat cells in response to insulin.
AG4OX mice overexpress GLUT4 in adipose tissue. They become obese, yet they're able to control blood glucose levels. AG4KO mice, in contrast, don't produce GLUT4 in adipose tissue. They have a normal body weight but develop insulin resistance and type 2 diabetes.
The researchers compared gene expression in adipose tissue from the 2 types of mice. Genes involved in making lipids were expressed at high levels in AG4OX mice but low levels in AG4KO mice.
These genes are known to be controlled by certain master regulator genes, so the team examined expression of these genes. This suggests that adipose tissue GLUT4 affects fatty acid synthesis and insulin sensitivity by regulating ChREBP.
But analysis of ChREBP expression in numerous mouse strains and people showed a more complicated releationship.
While ChREBP expression usually correlates with GLUT4 levels, it doesn't always. Even if it is, they may want to supervise your weight loss journey. There are certain changes you can make to your diet that can help you increase your insulin sensitivity.
This includes both adding and limiting various foods and supplements to your diet. Fiber can be divided into two broad categories — soluble and insoluble.
Soluble fiber helps feed the friendly bacteria in your gut, which have been linked to increased insulin sensitivity 14 , Discover the top 20 foods high in soluble fiber.
Many studies have found that eating a diet rich in plant compounds is linked to higher insulin sensitivity. This is because colorful fruits and vegetables are rich in antioxidants. Antioxidants bind to and neutralize molecules called free radicals that can cause harmful inflammation throughout the body 16 , 17 , Learn how much fruit you should eat per day and what to know about fruit as part of a diabetes eating plan.
Reducing your carb intake could help increase insulin sensitivity because high carb eating patterns tend to lead to spikes in blood sugar Eating regularly benefits insulin sensitivity, and eating low glycemic index GI carbs, in particular, is better because they slow the release of sugar into the blood, giving insulin more time to work efficiently 20 , Learn more about the types of carbs.
Added sugars , which are found mostly in highly processed foods, include primarily high fructose corn syrup and table sugar sucrose.
Many studies have found that higher intakes of fructose can increase insulin resistance among people with diabetes 22 , The effects of fructose on insulin resistance also appear to affect people who do not have diabetes, as reported in a review of literature showing that consuming a lot of fructose over less than 60 days increased liver insulin resistance, independent of total calorie intake Learn which foods contain lots of added sugar.
Herbs and spices, including fenugreek , turmeric , ginger , cinnamon , and garlic , have shown promising results in increasing insulin sensitivity 25 , Other herbs that may have this effect include basil, dill, fennel, parsley, cumin, nutmeg, oregano, and rosemary.
Research has identified at least compounds contained in a variety of herbs and spices that may contribute to reducing insulin resistance Several studies have found that drinking green tea can help increase insulin sensitivity and reduce blood sugar 27 , These beneficial effects of green tea could be due to its powerful antioxidant epigallocatechin gallate EGCG , which helps increase insulin sensitivity Vinegar could help increase insulin sensitivity by reducing blood sugar and improving the effectiveness of insulin It also appears to delay the stomach from releasing food into the intestines, giving the body more time to absorb sugar into the bloodstream Unlike other fats, trans fats provide no health benefits and increase the risk of many diseases Evidence on the effects of high trans-fat intake on insulin resistance appears to be mixed.
Some human studies have found it harmful, while others have not 33 , Many different supplements can help increase insulin sensitivity, including vitamin C , probiotics , and magnesium. That said, many other supplements, such as zinc, folate, and vitamin D, do not appear to have this effect, according to research As with all supplements, there is a risk they may interact with any current medication you may be taking.
Insulin is an important hormone that has many roles in the body. When your insulin sensitivity is low, it puts pressure on your pancreas to increase insulin production to clear sugar from your blood.
Low insulin sensitivity is also called insulin resistance. Insulin sensitivity describes how your cells respond to insulin. Symptoms develop when your cells are resistant to insulin.
Insulin resistance can result in chronically high blood sugar levels, which are thought to increase your risk of many diseases, including diabetes and heart disease.

A study in mice suggests a potential mechanism that could explain why only some individuals with obesity develop type 2 diabetes.

Diet, weight loss, and exercise can improve insulin resistance. However, most people need medicine as well. Your doctor may prescribe a medicine that works best for your health and lifestyle needs. If your insulin resistance leads to uncontrolled type 2 diabetes, you may need insulin given through a pump or daily injection. Living with insulin resistance requires lifestyle changes as well as regular use of prescription medicine. You will have to be more careful in making meal and snack choices, reading labels, and maintaining a lower weight.

How can I prevent or reverse insulin resistance and prediabetes? What is insulin? Being overweight or having obesity are risk factors for developing insulin resistance or prediabetes. Excess weight Experts believe obesity , especially too much fat in the abdomen and around the organs, called visceral fat, is a main cause of insulin resistance.
Physical inactivity Not getting enough physical activity is linked to insulin resistance and prediabetes. Doctors use blood tests to find out if someone has prediabetes. The following test results show Prediabetes 2 A1C—5. Insulin resistance happens when the body doesn't respond to the hormone insulin as it should, making it hard for glucose to get into cells.
Glucose comes from food and is the body's main source of energy. Normally, insulin helps glucose enter the cells. Insulin resistance can raise a child's risk for type 2 diabetes and other health problems.
To help improve the body's response to insulin, doctors recommend that kids and teens:. Insulin resistance is most common in people who are overweight and have too much belly fat.
Insulin resistance is also linked to some genetic syndromes, conditions that affect hormone levels and stress levels, and some medicines. Obesity and insulin resistance tends to run in families. Other things that put someone at risk for insulin resistance include:.
Doctors might think it's insulin resistance if an overweight or obese person has acanthosis nigricans, a family history of diabetes , or heart disease. They may:.

People with Antioxidant-rich foods for recovery resistance, Antioxidant-rich foods for recovery known as impaired insulin sensitivity, have built up a tolerance to insulin, making the hormone less effective. As a result, more insulin is needed to persuade fat and muscle cells to take up glucose and the liver to continue to store it. Just why a person fails to respond properly to insulin is still a mystery. But there are ways to make the body more receptive to insulin, which can help prevent or delay type 2 diabetes—or help someone with type 1 diabetes manage their blood glucose blood sugar.
