How often do you come across advice that claims walking 10,000 steps or breaking a sweat at the gym is the secret to losing weight? The truth, say experts, is far more complicated. Physical activity is undoubtedly important for good health, but for many, the body’s own biology can make losing weight an uphill task.
Managing obesity is not just a matter of willpower, says Dr Rajiv Kovil, Medical Director at Dr Kovil’s Diabetes Care Centre in Mumbai. “Genetics, metabolism, and hormonal imbalances play a massive role. Relying solely on diet and exercise often leads to frustration and weight regain.”
Understanding BMI and heart risk:
Body Mass Index, or BMI, is a basic measure that helps assess whether your weight is appropriate for your height. While it’s a simple number, its implications can be serious. “A high BMI usually signals excess body fat, which puts pressure on the heart and blood vessels,” explains Dr Kovil. “This strain increases the risk of high blood pressure, cholesterol build-up, and blocked arteries, all of which can lead to heart attacks or strokes.” He adds that nearly two-thirds of deaths related to high BMI are linked to heart disease. “Maintaining a healthy BMI through balanced eating, regular exercise, and, when necessary, medical intervention, is key to protecting long-term heart health,” he says.
Exercise and healthy eating are vital, they improve mood, strengthen the body, and support health. However, when it comes to obesity, they’re not always enough. The body can adapt to increased activity by conserving energy elsewhere, a process known as constrained energy expenditure.
“Some people’s bodies are simply resistant to weight loss,” notes Dr Kovil. Factors like genetics, hormones, or certain medications can make shedding weight difficult, even with consistent effort. In fact, the body often reacts to weight loss by slowing metabolism and increasing hunger, a biological mechanism that can cause regained weight over time.
This is where medical support can make a difference. Treatments such as semaglutide, which replicates a natural hormone (GLP-1) that helps regulate appetite and blood sugar, are being used to complement lifestyle changes. “It’s not a magic pill,” says Dr Kovil, “but when used under medical supervision, it can help people achieve more sustainable results.”

In the STEER study, those with obesity and heart disease who continued semaglutide treatment showed a lower risk of heart attack, stroke, or death. These findings suggest that such medications can support long-term health when paired with responsible lifestyle habits.
Dr Kovil outlines a few vital steps for anyone struggling with weight loss:
Keep track of your BMI: Aim to stay below 25 to reduce the risk of heart disease and diabetes. If lifestyle changes aren’t enough, speak to a doctor about medical options.
Understand your body: Sometimes biology resists change, and that’s not a personal failure. Medication can help your body respond better to healthy habits.
Seek medical advice early: Early guidance can prevent complications and support long-term wellbeing.
Get professional input: Rely on your doctor rather than fitness apps or social media advice for a clear picture of your health.
Focus on health, not just weight loss: combining exercise with pharmacotherapy preserves muscle and boosts cardiovascular and mental well-being.
