Weight gain is often blamed on overeating or lack of exercise. However, medical experts say this perception oversimplifies a far more complex biological process.

According to Dr Archana Pate, Consultant,

\n\n

Internal Medicine Fortis Hospital, Kalyan, obesity is not merely a lifestyle issue but a multifactorial metabolic disorder influenced by several internal and external factors.

“Obesity is often misunderstood as simply the result of overeating or lack of exercise. In reality, it is a multifactorial metabolic disorder influenced by a complex interaction of genetic, hormonal, environmental and lifestyle factors,” she explains.

\n\n

While unhealthy diets and sedentary behaviour certainly contribute to weight gain, Dr Pate notes that many individuals struggling with obesity may have underlying metabolic or medical conditions that make weight gain easier and weight loss significantly more difficult.

\n\n

These include endocrine disorders such as hypothyroidism, Cushing’s syndrome, polycystic ovarian syndrome (PCOS), insulin resistance and certain genetic predispositions. Additionally, some medications—including steroids, antidepressants and antipsychotics—can also contribute to weight gain.

Sleep disturbances, chronic stress and hormonal imbalances further complicate how the body regulates metabolism.

Highlighting a similar concern, Dr Manoj Bharucha, Gastroenterologist & Bariatric Surgeon, P.D. Hinduja Hospital & Medical Research Center, Khar says one of the biggest misconceptions he encounters is the belief that weight gain is simply a matter of calorie balance.

\n\n

“One of the most common misconceptions I encounter even among highly educated, health-conscious individuals is the assumption that weight gain is simply a matter of calories consumed versus calories expended. This reductive view not only fails patients; it actively prevents them from accessing the correct intervention,” he says.

According to Dr Bharucha, the human metabolic system cannot be reduced to a simple calorie calculator. Instead, it is a complex hormone-regulated system influenced by genetics, gut microbiome composition, sleep patterns, stress physiology and even early-life exposures.

\n\n

“When I see a patient who is gaining weight despite eating carefully and exercising regularly, my first question is never ‘What are you eating?’ but rather ‘What is your body doing with what you eat?’” he explains.

One key biological driver is insulin resistance, a condition that is becoming increasingly common even among people who may appear lean. As cells become less responsive to insulin, the body compensates by producing higher amounts of the hormone to maintain blood sugar control.

Persistently high insulin levels can encourage fat storage, particularly around the abdomen.

\n\n

“This is a biological signal, not a behavioural mistake,” Dr Bharucha emphasises.

Other medical factors can also influence weight gain. Subclinical hypothyroidism, elevated cortisol levels caused by chronic psychological stress, disrupted circadian rhythms and an imbalanced gut microbiome can all independently contribute to metabolic changes.

Dr Bharucha notes that in some cases, identifying and correcting an underlying hormonal imbalance can significantly alter a patient’s metabolic profile, even without major dietary changes.

\n\n

Dr Pate stresses that recognising obesity as a medical condition rather than simply a lifestyle issue is crucial for effective treatment.

Because obesity is associated with several serious health risks, timely diagnosis and management become essential. These complications can include type 2 diabetes, hypertension, heart disease, fatty liver disease, obstructive sleep apnea, osteoarthritis, infertility and certain cancers. Beyond physical health, obesity can also affect mental wellbeing and quality of life.

\n\n

“Proper evaluation helps identify secondary causes or metabolic triggers, allowing doctors to design more targeted treatment strategies rather than relying only on calorie restriction,” she says.

Today, treatment approaches for obesity have become increasingly comprehensive. According to Dr Pate, effective management may involve structured lifestyle modification, medical nutrition therapy, behavioural counselling, pharmacotherapy and, in selected cases, bariatric surgery.

Experts emphasise that a personalised treatment plan tailored to an individual’s metabolic profile offers the best chance of achieving sustainable weight management.

\n\n

Ultimately, both doctors agree that understanding the biological drivers behind weight gain is key to reducing stigma around obesity.

As Dr Bharucha puts it, “Weight is a symptom. Effective treatment requires understanding the cause.”
