You think having tea without sugar is keeping you safe from diabetes? Here’s what a Mumbai-based doctor says

You know what you see everywhere these days? People sipping their morning chai without sugar, feeling virtuous, convinced they've cracked the code to diabetes prevention. It's become this comfortable myth, just ditch the sugar, stay safe. But here's what Dr. Shehla Shaikh, an endocrinologist at Saifee Hospital in Mumbai, wants you to understand: that belief is dangerously incomplete. You could be drinking tea without a single granule of sugar and still develop diabetes. In fact, plenty of young people are doing exactly that."Many individuals believe that simply avoiding sugar in their tea and coffee will keep them free from diabetes," Dr. Shaikh explains. "Of course, lowering one's sugar consumption is helpful; however, experts say that some other routines are more significant than this simple solution and affect blood sugar levels much more."Diabetes isn't about sugar alone. It's about what your whole life looks like, how you sit, how you sleep, how stressed you are, what you eat beyond just the sweet stuff.Walk into any corporate office and you'll see it immediately. Rows of people planted in chairs for eight hours straight, bodies barely moving, feet barely touching the floor. This sedentary existence has become so normal that we've stopped noticing how abnormal it really is. But it's wrecking our metabolisms. Research has shown that each additional hour of sitting time per day increased the risk of developing diabetes by 22%. Studies have shown that sedentary behaviour is inseparable from all-cause mortality, cardiovascular disease mortality and tumour mortality. This isn't just about blood sugar anymore. This is existential health territory. What happens when you sit that much is your insulin stops working properly. Your cells become resistant to it. The mechanism is real and documented. When muscles don't move, they don't take up glucose. Your pancreas keeps pumping out insulin, your body keeps getting more resistant, and slowly you slide toward diabetes without ever touching a piece of candy. Dr. Shaikh emphasizes that sedentary lifestyle leads to such illnesses as diabetes, high blood pressure, and high cholesterol and is just as bad as smoking. Sitting at your desk is equivalent to smoking. Except you're doing it at work, in front of your boss, feeling responsible and productive.But even if you manage to drag yourself away from your chair, there's another saboteur quietly destroying your blood sugar management: sleep. Or rather, the lack of it. Most of us are chronically tired, staying up late for work or scrolling, then waking up early. We've normalized this exhaustion, but our bodies haven't evolved to handle it.In laboratory studies of healthy young adults submitted to recurrent partial sleep restriction, marked alterations in glucose metabolism including decreased glucose tolerance and insulin sensitivity have been demonstrated. Even healthy people start acting like pre-diabetics when you take away their sleep. Lack of sleep prompts the body to produce less insulin, the hormone that regulates blood sugar, and more stress hormones like cortisol, which hinders insulin's effectiveness.And then there's stress. Chronic stress is like pouring cortisol into your bloodstream day after day. High cortisol levels cause your liver to release more glucose into your bloodstream. Over time, this can cause insulin resistance. The worst part? You're not even eating anything to deserve these blood sugar spikes. Your body is manufacturing a problem that your diet can't solve.Dr. Shaikh points out that chronic stress can also increase the risk of developing type 2 diabetes two to three times. That's not a minor risk factor. That's three times higher. And nobody's running ads about it. You don't see meditation apps positioned as diabetes prevention tools, even though they should be.Then there's the food deception. You see a package that says "sugar-free" and your brain checks a box marked "safe." But here's what's actually in there: refined flour, processed oils, additives designed to make you crave more. While the label may say "sugar free" or "no sugar added," there could still be ingredients that will impact your blood glucose levels. The irony is that claims like "sugar-free," "reduced sugar" or "no sugar added" do not necessarily mean carbohydrate-free or lower in carbs than the original version of the food nor do they automatically mean low-calorie. You're being lied to by marketing. Those "healthy" sugar-free biscuits are still refined, stripped of fiber, and designed to spike your blood sugar.What matters is fiber and whole foods. When you eat a salad before eating protein, when you eat whole grains instead of white bread, when you choose real food instead of processed alternatives, your body responds differently. The glucose enters your bloodstream slowly. Your insulin has time to work. Your cells actually respond to it.Dr. Shaikh says the solution isn't mysterious. Short or disrupted sleep can raise your risk by 40% to 80%, but seven to eight hours of quality sleep can reverse that. Regular exercise, standing and walking around every hour, consuming healthy diets with fiber and protein, limiting processed food, minimizing stress—these aren't revolutionary. But they require changing your entire life, not just your chai order.That's the conversation nobody wants to have. It's easier to blame sugar than to admit you need to sleep more, move more, and redesign your job. But Dr. Shaikh is right. Drinking unsweetened tea while sitting at your desk for ten hours, stressed and sleep-deprived, eating processed "sugar-free" snacks, isn't safety. It's just denial.
