Lowering your risk of developing type 2 diabetes usually involves tackling a combination of changes to your diet and exercising regularly. But new research suggests that the key to meaningfully lowering your type 2 diabetes risk may be in small bursts of exercise you can do throughout the day.<\/p>\n
The study, which was published in the journal Diabetes Care<\/a>, found that doing up to four minutes a day of short bursts of moderate-intensity activity could lower the risk of developing type 2 diabetes by more than a third.<\/p>\n For the study, researchers analyzed health and activity data from 22,706 people in the U.K. who didn\u2019t have a regular exercise routine. During the nearly eight-year follow-up period, 665 participants were diagnosed with type 2 diabetes.<\/p>\n The researchers specifically looked at two different types of activity: bouts of vigorous intermittent lifestyle physical activity (VILPA) that lasted a minute or less, and bouts of moderate- to vigorous-intensity equivalent (MV-ILPA) that lasted for up to three minutes.<\/p>\n The researchers found that doing about 3.9 minutes per day of VILPA lowered the risk of developing type 2 diabetes by 36%. People who did 25 minutes a day of MV-ILPA saw their risk of developing the disease drop by 46%.<\/p>\n Meet the experts: Richard Siegel, M.D<\/a>., co-director of the Diabetes and Lipid Center at Tufts Medical Center and Endocrinologist at Tufts Medicine Weight & Wellness Center\u2013Stoneham; Kathleen Dungan, M.D., M.P.H.,<\/a> an endocrinologist and professor in the Division of Endocrinology, Diabetes & Metabolism at The Ohio State University; Emmanuel Stamatakis, Ph.D.<\/a>, study co-author and professor of physical activity, lifestyle, and population health at Monash University.<\/p>\n \u201cType 2 diabetes is one of the fastest-growing chronic diseases on the planet, projected to affect more than 1.3 billion people by 2050\u2014around 15-20% of the world’s projected population by then\u2014and structured exercise is still a first line lifestyle recommendation to prevent it,\u201d says Emmanuel Stamatakis, Ph.D.<\/a>, study co-author and professor of physical activity, lifestyle, and population health at Monash University. \u201cThe problem is that around four in five adults don’t do regular exercise in leisure time, and most never will.\u201d<\/p>\n The findings make a case for being active in small amounts in everyday life to lower the risk of type 2 diabetes, even if you don\u2019t have a formal exercise routine in place. Here\u2019s why.<\/p>\n Why might small activity bursts lower the risk of type 2 diabetes?<\/p>\n It\u2019s important to note a few things first. One is that the study focused on people who didn\u2019t have a set exercise routine in place, so it\u2019s unclear how this may impact people who exercise regularly. Another is that the study found a link between doing short bursts of activity and a lowered risk of developing type 2 diabetes\u2014it didn\u2019t prove that these activity bursts lowered the risk.<\/p>\n Still, doctors say there are a few reasons why this can be helpful for lowering the risk of type 2 diabetes. Small bursts of activity may help the body take in glucose (i.e. blood sugar) more easily, says Richard Siegel, M.D<\/a>., co-director of the Diabetes and Lipid Center at Tufts Medical Center and Endocrinologist at Tufts Medicine Weight & Wellness Center\u2013Stoneham.<\/p>\n It could also improve insulin sensitivity, Dr. Siegel says. (Insulin<\/a> is a hormone secreted by the pancreas that helps to escort glucose into cells to be used for energy.) When insulin sensitivity is high, the cells can more efficiently use glucose\u2014that\u2019s already linked to a lower risk of type 2 diabetes. (However, insulin resistance, which is when the body doesn\u2019t effectively use insulin, is linked<\/a> to a higher risk of type 2 diabetes.)<\/p>\n \u201cThe biology is essentially the same machinery that makes structured exercise protective, just delivered in smaller, more frequent doses,\u201d Stamatakis says. \u201cWhen you push up a flight of stairs or carry heavy shopping bags for a minute or two, your muscles suddenly need fuel, and they pull glucose straight out of your bloodstream to power those contractions.\u201d Your muscles can do this even when insulin isn\u2019t working perfectly in your body, he says.<\/p>\n \u201cDo this several times a day, day after day, and you’re keeping the body’s sugar-clearing system in good working order,\u201d Stamatakis says. \u201cOver time, even short vigorous moments nudge your fitness upward, and fitness is one of the strongest known protectors against type 2 diabetes.\u201d<\/p>\n The high-intensity bursts of brief activity could even produce more mitochondria\u2014the powerhouse of the cells\u2014and help people to burn more calories, even after they\u2019re done with the activity, says Kathleen Dungan, M.D., M.P.H.,<\/a> an endocrinologist and professor in the Division of Endocrinology, Diabetes & Metabolism at The Ohio State University.<\/p>\n But these small bursts of exercise may simply be more approachable for some people, raising the odds they\u2019ll consistently be more active than if they were trying to follow a structured exercise plan, Dr. Siegel says. \u201cExercise \u2018snacks\u2019 like this are easy to do and can break up sedentary activity, which is also useful,\u201d he says. \u201cThey do not require extra cost or equipment.\u201d<\/p>\n Dr. Dungan agrees. \u201cThe traditional recommendations to incorporate 30 minutes of moderate physical activity per day are actually more flexible than that,\u201d she says. \u201cPeople can break it up in short, unplanned bursts throughout the day and achieve the same benefits.\u201d<\/p>\n What daily activity can help lower the risk of type 2 diabetes?<\/p>\n The researchers broke daily activity into two categories: vigorous intermittent lifestyle physical activity, or VILPA, and the moderate-intensity equivalent (M-VILPA). With vigorous activity, people may feel an increase in their heart rate and may only be able to speak a few words. When they\u2019re doing moderate activity, people will usually notice their breathing is faster. They can talk, but not sing.<\/p>\n Here are a few examples of VILPA, per the researchers:<\/p>\n Running for the bus or trainPower walking while doing errandsClimbing stairsCarrying shopping bags or a backpack that weighs at least 10% of your own bodyweightWalking uphillPlaying high-energy games with kids or petsDoing heavy household chores or gardening<\/p>\n These are a few examples of M-VILPA, according to the researchers:<\/p>\n Brisk walkingDoing household chores at a moderate intensityWalking while carrying shopping bags or a backpack that weighs around 5% of your bodyweightOther ways to lower the risk of type 2 diabetes<\/p>\n While short bursts of activity throughout the day can help to lower the risk of developing type 2 diabetes, there are other things you can do to reduce the odds of developing the disease, per the National Institute of Diabetes and Digestive and Kidney Diseases<\/a> (NIDDK):<\/p>\n
