Think 10,000 Steps Are Enough? Top Doctor Warns of Hidden Diabetes and BP Risks

Hitting 10,000 steps daily has always been seen as the gold standard of good health. But what if that belief is giving you a false sense of security? According to Dr. Sudhir Kumar, a neurologist trained at Christian Medical College Vellore, many people may be unknowingly putting themselves at risk of diabetes, obesity, and hypertension – despite staying active. Drawing from real OPD experiences, Dr. Kumar highlights a growing disconnect between perceived healthy habits and actual metabolic health. Patients often report daily walks, reduced sugar intake, and regular household activity. Yet, their medical reports frequently reveal worsening blood sugar levels, rising blood pressure, and increasing fat accumulation. “Every day, I see patients with

obesity, type 2 diabetes, or hypertension who tell me: 'I walk every morning, Doctor." "I do all the household work." "I have stopped adding sugar to my tea." They feel they have done their part. But their blood work and body composition tell a different story,” Dr. Kumar wrote on X.

From the OPD: The Most Dangerous Health Misconception I See Every DayThe most frustrating part of my OPD practice is not the complex neurological cases; it is watching patients lose a battle they think they are winning.Every day, I see patients with obesity, Type 2 Diabetes,…

What is the exercise trap?

Walking is undeniably beneficial, but it is not enough on its own. According to Dr. Kumar, it is a misconception, as the exercise trap. While walking helps burn calories, it does little to prevent muscle loss, especially after you turn 30 years old. This gradual decline in muscle mass, known as sarcopenia, can reduce metabolic efficiency. Muscle plays a crucial role as the body’s primary glucose sink, meaning it helps regulate blood sugar levels. Without enough muscle, even active individuals may develop insulin resistance, a key driver of type 2 diabetes. Dr Kumar recommends strength training at least twice a week, using weights, resistance bands, or bodyweight exercises. Unlike walking, resistance training builds muscle that continues to burn glucose even at rest, significantly improving metabolic health. “Walking burns a few calories while you do it. Strength training builds the "engine" that burns glucose even while you sleep. If you are not lifting weights or doing resistance training at least twice a week, your insulin resistance will likely persist, regardless of your step count,” he added.

The diet trap

Another common mistake lies in diet. Many believe cutting sugar alone is sufficient. However, Dr Kumar warns this is a partial fix at best. Typical Indian diets remain high in carbohydrates, which include rice or rotis, while being low in protein. Even without added sugar, such meals can cause repeated insulin spikes, contributing to fat gain and poor glucose control. “Refined carbohydrates (even without added sugar) spike insulin similarly to sugar. Furthermore, a protein-deficient diet leads to muscle loss and increased hunger,” wrote Dr. Kumar. Protein, on the other hand, plays a vital role in preserving muscle mass, regulating hunger hormones, and improving metabolic efficiency. Dr. Kumar suggests aiming for 1.2–1.5 grams of protein per kilogram of body weight daily. Increasing protein intake often naturally reduces cravings for excess carbohydrates, creating a more balanced and sustainable diet.

Muscle is more than strength

From a neurological perspective, muscle health impacts more than just metabolism. Dr. Kumar explains that muscles act as an endocrine organ, releasing myokines during strength training. These compounds can:

• Reduce inflammation
• Improve brain function
• Potentially lowers the risk of neurodegenerative diseases like Alzheimer’s disease

This makes strength training not just a fitness tool, but a long-term brain health strategy. He advises the following for real change in health and fitness:

Stop "just walking"

Add two days of resistance training, which includes bodyweight, bands, or weights.

Flip the plate

Start your meal with protein – including paneer, eggs, sprouts, lean meat. Eat your carbs last, and in smaller portions.

Recognize household work as "activity," not "exercise"

Exercise requires progressive overload. Sweeping the floor doesn't challenge your muscles the way a squat does.
