You are not eating too much, you are eating too often: Cardiologist Dr. Pradip Jamnadas flags the silent insulin trouble few notice

Insulin resistance is increasingly being discussed as a silent driver behind modern lifestyle diseases, and a recent Instagram post by US-based cardiologist Dr Pradip Jamnadas has brought the issue back into public focus. His message is direct and provocative. The real problem, he suggests, is not just what people eat, but how often they eat.

A warning that goes beyond body weight

In his video, Dr Jamnadas explained that insulin resistance can develop even in people who do not appear overweight. According to him, constant eating keeps insulin levels elevated throughout the day, leaving the body little chance to reset. Over time, this persistent hormonal overload makes cells less responsive to insulin, pushing the body toward metabolic trouble.

He emphasised that chronically high insulin levels, not calories alone, are at the root of the issue. Frequent meals and snacks, he warned, prevent insulin from dropping to healthy levels, increasing the risk of high blood pressure and other complications.

Why fasting enters the conversation

Dr Jamnadas, who has more than 31 years of clinical experience and is the founder of Cardiovascular Interventions in Orlando, argues that restoring insulin sensitivity requires a break from constant eating. He advocates structured fasting, not calorie counting, as a way to allow insulin levels to fall naturally.

His approach focuses on limiting meals to once or twice a day rather than continuous grazing. By doing so, he believes the body can shift into a metabolic state that supports insulin sensitivity and long-term cardiovascular health.

What medical science says about insulin resistance

Clinical research supports the seriousness of insulin resistance, even if treatment approaches vary. According to a detailed report published by the Cleveland Clinic, insulin resistance occurs when cells in the muscles, fat and liver stop responding effectively to insulin. This forces the pancreas to produce more insulin to keep blood sugar levels stable, a condition known as hyperinsulinemia.

Over time, this imbalance can lead to elevated blood sugar levels, prediabetes and eventually Type 2 diabetes. The Cleveland Clinic notes that insulin resistance is also linked to obesity, cardiovascular disease, metabolic syndrome, fatty liver disease and polycystic ovary syndrome.

Who is at risk and why it often goes unnoticed

Insulin resistance does not always produce early symptoms. As long as the pancreas can compensate by making more insulin, blood sugar levels may remain normal. This makes the condition easy to overlook for years.

When it progresses, symptoms can include fatigue, increased thirst, frequent urination, blurred vision and unexplained weight changes. Some people may also develop skin changes such as darkened patches around the neck or underarms, a sign highlighted in the Cleveland Clinic report.

Lifestyle choices that shape insulin sensitivity

While genetics and age play a role, lifestyle factors are major contributors. The Cleveland Clinic identifies excess abdominal fat, physical inactivity and diets high in processed carbohydrates and saturated fats as key drivers of insulin resistance.

Regular physical activity improves how muscles use glucose, while balanced diets that limit refined sugars and high-glycaemic foods can ease the burden on insulin. Foods such as legumes, vegetables, nuts and lean proteins are generally better tolerated by the body’s insulin response.

A growing focus on prevention

There is currently no medication that directly treats insulin resistance itself. Instead, doctors focus on managing related conditions such as high blood pressure, elevated cholesterol or diabetes. Lifestyle changes remain the cornerstone of prevention and management.

Dr Jamnadas’s message fits into this broader preventive approach. His emphasis on fasting aims to address insulin resistance before it escalates into more serious disease.

What experts advise before making changes

While fasting has gained popularity, medical experts caution against extreme dietary shifts without guidance. The Cleveland Clinic advises people concerned about insulin resistance to consult healthcare providers, who can assess risk factors and recommend personalised strategies.

The growing attention around insulin resistance reflects a larger shift in healthcare conversations. Rather than reacting to disease after it develops, doctors are increasingly urging people to understand the hormonal patterns shaping their long-term health.
