Let Us Preserve Our Beta Cells…!!! Obesity, Beta Cells, and the Hidden Link to Diabetes

Obesity is one of the strongest risk factors for type 2 diabetes. Around 60–70% of people with diabetes are either obese or overweight. For Indians, even a BMI above 23 is considered overweight, above 25 obese, and above 30 morbidly obese. Excess body fat, especially inside the abdomen (visceral fat), increases insulin resistance, forcing the pancreas to work harder to maintain normal blood sugar. The pancreas does this through its beta cells, which normally keep glucose between 70–140 mg/dL. But repeated exposure to high-calorie, high-sugar, low-fiber diets puts these cells under constant strain. Over time, beta cells become fatigued and begin to fail. By the time fasting blood sugar reaches 126 mg/dL—the cut-off for diabetes—nearly half to two-thirds of beta cells are already lost. Preserving the remaining cells is therefore of utmost importance. Lifestyle changes are the most effective way to protect beta cells. Regular exercise, a healthy diet, and maintaining normal weight reduce the workload on the pancreas. Indians require at least 250 minutes of brisk walking per week, compared to 150 minutes for Caucasians. Avoiding sweets, fried foods, and excess fat, while ensuring adequate hydration (1.5–2 liters per day), is equally important. Medications that overstress beta cells should be used cautiously to avoid accelerating their decline. Protecting beta cells through lifestyle, diet, regular exercise, and the use of a few drugs (SGLT2i, GLP-1a, etc.), which help protect beta cells, delay their aging, and improve their secretory function, is essential for a healthy future for people with diabetes. Technology is the key to delaying complications and living healthier with diabetes. Expert- Dr Sunil Gupta Anchor- Mrs. Kalyani Gokhale Recorded on: 20/05/2025 Recorded at: Akashwani Nagpur
