What most people miss about weight loss: How an AIIMS gastroenterologist lost 15 kg, reversed fatty liver, and boosted energy naturally

Weight loss and metabolic health remain daily challenges for millions worldwide. While fad diets and grueling workouts often dominate mainstream advice, Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford, highlights gut health as the foundation for lasting transformation. Drawing from his personal journey, Dr. Sethi demonstrates how simple, gut-focused lifestyle adjustments can yield profound results: significant weight reduction, enhanced energy levels, and even reversal of conditions such as fatty liver. By prioritising the gut’s role in metabolism, digestion, and overall wellbeing, he shows that sustainable health isn’t about extreme restrictions but strategic, science-backed habits that nurture the body from within. Gut health, he asserts, is the true key to lasting vitality.


Why diets often fail: Dr. Sethi’s personal struggle revealed

For many, weight loss is a frustrating cycle of short-lived success and long-term disappointment. Dr. Sethi spent years attempting every conventional method: from calorie-counting diets to high-intensity workouts and restrictive meal plans. Despite these efforts, the results never lasted.

He explains, “I tried multiple diets and workout routines, but the weight always returned. It was exhausting and demotivating.” This experience mirrors what millions encounter worldwide: a lack of sustainable strategies that address the root cause of metabolic imbalance. The turning point for Dr. Sethi came during his GI and Hepatology fellowship, where he realized that gut health is the foundation of overall wellness. The gut is not just a digestive organ—it plays a crucial role in immunity, metabolism, mental clarity, and energy balance.

By shifting his focus from calories and workouts to improving gut function, Dr. Sethi discovered a more effective and sustainable approach to weight loss. “Once I prioritised my gut health, everything changed—from my energy levels to my metabolic markers,” he shares.

This insight challenges the conventional diet-centric mindset and emphasizes the importance of nourishing the gut for holistic health outcomes.


15 kgs lost and fatty liver reversed: 3 Simple lifestyle changes that revolutionised his gut health

Through gut-focused lifestyle adjustments, Dr. Sethi achieved remarkable results. Over several months, he lost 15 kilograms (approximately 30 lbs), reversed fatty liver, improved sleep quality, and stabilized energy levels throughout the day. Moreover, he transitioned out of pre-diabetes and enhanced cognitive focus. This transformation was not just physical; it was a complete metabolic and mental reset. His personal journey validates that targeting gut health can have ripple effects across multiple aspects of well-being.

Dr. Sethi’s approach stands out because it targets foundational habits rather than superficial fixes. Here are the three critical changes that made the biggest difference:

• From counting calories to counting ingredients

Rather than obsessing over the number of calories consumed, Dr. Sethi shifted his attention to what was in his food. Hidden sugars, processed oils, and inflammatory additives often sabotage weight loss and gut health, even when calorie intake seems controlled. By focusing on ingredient quality, he allowed his gut microbiome to thrive, which improved digestion, nutrient absorption, and overall metabolism. This method encourages mindful eating, where the focus is on nourishing the body rather than restricting it.

• From cutting carbs to controlling sugar spikes

Instead of eliminating carbohydrates completely, Dr. Sethi learned to pair carbs with fiber, protein, and healthy fats. This combination prevented blood sugar spikes, a major contributor to fat accumulation, insulin resistance, and energy crashes. Balancing glucose levels through strategic food combinations proved far more effective and sustainable than restrictive low-carb diets. This approach also highlights how gut health influences metabolic control and weight management.

• From low-fat processed foods to real, fiber-rich foods

Dr. Sethi emphasised the importance of real, whole foods over processed low-fat options. Fiber-rich foods such as vegetables, whole grains, and legumes nourish the gut microbiome, supporting digestion, immunity, and long-term metabolic health. By eating foods that naturally support gut bacteria, he created a self-reinforcing cycle: improved gut function led to better energy, weight control, and reduced fatty liver risk.


How a strong gut supports weight loss and overall wellness

Dr. Sethi’s journey underscores a critical principle: lasting health improvements do not come from quick fixes but from addressing the root causes. The gut is the body’s foundation. When it functions optimally, metabolism, immunity, cognitive function, and energy levels all improve naturally.

“Through my experience and with my patients, I’ve realized that fixing the gut sets the stage for all other health transformations,” he explains.
