Where fat accumulates in the body can be far more important than simply shedding pounds when it comes to lowering diabetes risk, a new study published in Nature suggests. For people with prediabetes, which is when blood sugar is higher than normal but not yet at diabetes levels, targeting belly fat specifically may have a greater impact than losing weight overall through lifestyle changes.Halting prediabetes is critical, as nearly 70 percent of individuals in this category eventually develop diabetes. Reversing prediabetes also protects against complications like heart disease, kidney problems, and nerve damage.What About Study Findings?In the study, two groups of participants had similar overall fat levels but differed in how fat was stored. Those who lost more belly fat, or visceral fat, over a year were able to reverse prediabetes, while those who didn’t reduce abdominal fat did not reach healthy blood sugar levels.Researchers from the University Hospital Tübingen in Germany found that focused lifestyle changes could bring prediabetic individuals into remission even without major weight loss. This remission was associated with a roughly 70 percent reduction in the risk of developing Type 2 diabetes over the following decade.Among 1,105 participants with prediabetes, the study examined 234 individuals who did not lose overall weight. Of these, 51 achieved prediabetes remission after a year of targeted lifestyle interventions, while the remaining 183 did not reach healthy glucose levels.Does This Study Hold Lessons for Indians?“Weight loss remains the primary goal for people who are obese. However, reversing prediabetes can also happen without major weight loss, especially when lifestyle interventions focus on improving diet quality, increasing physical activity, and building muscle while reducing fat,” says Dr. Anoop Misra, chairman at Fortis C-Doc Hospital for Diabetes and Allied Sciences.He adds that for Indians, reducing both subcutaneous abdominal fat and visceral fat is key for better metabolism. These changes, paired with increased muscle mass and improved functional capacity, enhance insulin sensitivity and help maintain long-term blood sugar control.Why Abdominal Obesity Is a PriorityBelly fat, or visceral fat, releases inflammatory substances that interfere with insulin, the hormone that moves sugar from the blood into cells. To compensate, the body produces more insulin, which can overwhelm the pancreas and raise blood sugar. Excess sugar is often stored as fat around the abdomen, which is why even individuals of normal weight with a protruding stomach are at higher risk of diabetes.What Lifestyle Interventions Help Reduce Belly Fat?“Diet composition matters most lower carbs, higher protein, and healthy fats, all within a controlled calorie range, can help reverse prediabetes even without significant weight loss,” says Dr. Misra. Good carbohydrate sources include whole grains, fruits, legumes, and non-starchy vegetables, while healthy fats come from nuts, seeds, olive oil, and fatty fish.Physical activity also plays a crucial role. Combining resistance training, such as weightlifting at least twice a week, with aerobic exercises like walking, running, or swimming, is effective at reducing visceral fat. Adequate sleep around seven hours per night is also essential to keep blood sugar levels under control.
