Cardiologist Details Evidence-Based Fasting Strategies to Reduce Harmful Visceral Fat

Post by : Saif Nasser

Many people find abdominal fat stubborn to shift despite calorie control and exercise. Importantly, visceral fat sits deep around organs and carries a greater risk of serious conditions such as heart disease, type 2 diabetes and high blood pressure.

Dr. Pradip Jamnadas, an Orlando-based cardiologist with over 31 years of clinical experience, discussed practical fasting approaches during a podcast with Steven Bartlett. He described fasting as a controlled, physiological method to reduce deep abdominal fat and improve metabolic health.

Dr. Jamnadas explains that structured fasting allows the body time to recover and mobilise stored fat for fuel. Unlike extreme crash diets, properly applied fasting preserves metabolic function and limits rapid weight regain, providing a steadier path to fat loss.

Recommended entry-level fasting schedule

For those new to time-restricted eating, Dr. Jamnadas recommends the 12-12 routine: twelve hours without food followed by a twelve-hour eating window. For instance, finishing dinner at 7pm and delaying the next meal until 7am. During fasting hours, calorie-free beverages such as water, plain tea or black coffee are acceptable.

He advises sustaining this pattern for two to three weeks so the body can adapt before progressing to a more intensive regimen like 18-6.

In the 18-6 model, calorie intake is confined to a six-hour period while fasting continues for the remaining 18 hours. Maintaining hydration with non-caloric drinks during the fast is important. Dr. Jamnadas notes this approach can accelerate fat loss and improve insulin handling, which helps reduce diabetes risk and limit weight gain.

Approach for obese patients and those with diabetes

Patients with marked obesity or established diabetes require a tailored plan. Dr. Jamnadas may recommend intermittent extended fasts, such as a supervised 48-hour fast once weekly, to drive reductions in stored fat and lower blood glucose.

He also described a protocol that combines a three-day water-only fast every nine days with OMAD (one meal a day) as a more aggressive option for select patients, emphasising that such strategies demand clinical oversight.

Fasting versus starvation

Dr. Jamnadas stressed that fasting should not be conflated with starvation. It is a deliberate pattern of eating designed to give the body intermittent respite from digestion so repair mechanisms engage and stored fat is used for energy.

During fasting periods insulin levels fall, which promotes fat mobilisation. Patients often report steadier energy, less inflammation and improved cardiac function. However, he warns that adequate hydration is essential and that sugary drinks or snacks must be avoided while fasting.

Potential long-term health gains

Lower blood sugar levels

Reduced risk of heart disease

Improved insulin sensitivity

Decrease in abdominal fat and systemic inflammation

Better digestion and sleep quality

He recommends prioritising whole foods during eating windows—vegetables, fruits, lean proteins and healthy fats—and steering clear of processed foods, added sugar and refined carbohydrates.

A natural, measured approach

Dr. Jamnadas' guidance has attracted attention because it frames fasting as a natural, evidence-aligned strategy rather than a quick-fix fad. His emphasis is on discipline, balanced nutrition and an understanding of metabolic physiology.

Consistency matters more than rapid results. He cautioned that meaningful change takes time and patience, but with adherence fasting can reduce visceral fat and strengthen overall health.

At the same time, he reiterated that fasting is not appropriate for everyone: people with certain medical conditions, pregnant women, and those on ongoing medications should seek medical advice before adopting any fasting protocol.

Key takeaway

Dr. Pradip Jamnadas highlights that strategic fasting—properly supervised and combined with sensible nutrition—can be an effective, safe method to lower harmful belly fat, improve metabolic markers and protect cardiovascular health.

Visceral fat can be managed through informed lifestyle changes. With medical guidance, adequate hydration and steady commitment, patients can pursue better metabolic and cardiac outcomes.
