When 66-year-old dance teacher Will McKechnie walked into his routine NHS health check, he never imagined he’d walk out with a warning: he was prediabetic. With an active lifestyle that involved working out seven times a week, a trim 11st 13lb frame, and no obvious health issues, McKechnie seemed the embodiment of wellness but beneath his fit exterior was a metabolic red flag, a silent threat that could’ve easily been missed.His case disrupts a common misconception: that type 2 diabetes is a condition exclusive to the overweight or sedentary. In fact, McKechnie’s story proves how poor eating habits regardless of fitness level can quietly erode health.The term “prediabetes” refers to blood sugar levels that are higher than normal but not yet high enough for a diabetes diagnosis. It’s a condition that affects more than 6.3 million people in England alone, often without symptoms. During an “over-60s MOT” in May 2023, McKechnie’s blood sugar levels measured at 44 mmol/mol, placing him squarely in the prediabetic range (42–47 mmol/mol). Anything above 48 mmol/mol is considered full-blown type 2 diabetes.“When my doctor said if it hit 48 it would likely become irreversible, I was terrified,” McKechnie admitted. “I thought being active was enough. I never saw this coming.”For years, McKechnie believed his active lifestyle gave him immunity against dietary indulgences. Every night, he treated himself to a Yorkie chocolate bar and a packet of crisps—a habit he saw as harmless. But those calorie-dense, high-glycemic snacks quietly wreaked havoc on his metabolism.Experts warn that regular consumption of processed carbs and sugar, especially before bed, can contribute to insulin resistance, the very mechanism behind type 2 diabetes. While physical activity does play a major role in regulating blood glucose, dietary quality and timing are equally important—something McKechnie learned the hard way.How Lifestyle Tweaks Reversed the RiskAfter the diagnosis, McKechnie overhauled his diet. He didn’t just eliminate sugary snacks—he also changed how he ate. Adopting a slower, more mindful eating practice, he allowed himself to feel full sooner and consume fewer calories.“It now takes me 40 minutes to eat a simple chicken sandwich,” he shared. “That one change helped me eat less without feeling deprived.”A remarkable drop in blood sugar from 44 to 41 mmol/mol in just nine months—bringing him out of the prediabetic zone. He also lost nearly two stone and trimmed two inches off his waistline.Prediabetes often goes undiagnosed due to its subtle or nonexistent symptoms. But if left unchecked, it can lead to type 2 diabetes, a condition responsible for serious complications like heart attacks, strokes, kidney failure, blindness, and limb amputations.In the UK alone, diabetes costs the NHS £10 billion annually, and globally, the numbers are rising with alarming speed. The World Health Organization warns that type 2 diabetes is one of the world’s fastest-growing chronic diseases, with lifestyle-related factors as the primary drivers.Why Its Important To Rethink the Stereotypes?Many associate prediabetes with obesity or advanced age, but McKechnie’s case proves that even slim, physically active individuals aren’t immune. While excess weight is a major risk factor, so are genetics, poor diet, stress, poor sleep, and even eating habits like snacking late at night or eating too quickly. Symptoms, when present, may include:Frequent urinationExcessive thirstFatigueBlurred visionUnexplained weight lossSlow-healing cutsItchy genitalsBut most people with prediabetes will have no symptoms at all, making routine screening especially critical.Importance of Early Detection and Testing for Diabetes DiagnosisMcKechnie’s condition might have gone unnoticed had his GP not revisited old test results nearly a year later. That delay spotlights a growing issue: undetected or poorly communicated results that put patients at unnecessary risk.He now advocates for regular blood sugar testing, even for those who appear outwardly healthy. “It’s not just worth it—it’s life-changing,” he says. “Don’t wait for symptoms. Get tested.”Routine blood tests, especially for individuals over 40 or with a family history of diabetes, can identify prediabetes early—when it’s still reversible with lifestyle changes.Why the Term ‘Prediabetes’ Could Create Panic?The term prediabetes isn’t without controversy. Some experts argue that it medicalizes borderline results and creates unnecessary panic. However, advocates say the term serves as a wake-up call, offering a window of opportunity for intervention before permanent damage occurs.In McKechnie’s case, it was just that. “Had I waited, I could’ve crossed the threshold into something far more difficult to manage.”Will McKechnie’s story is a powerful reminder that fitness doesn’t grant immunity from metabolic disease. No matter how many workouts we log, what we put in our mouths and how and when we eat it matters deeply.His recovery shows that it’s never too late to course-correct. With small but consistent lifestyle changes, he reversed a dangerous diagnosis, lost weight, improved his energy levels, and possibly added years to his life.
