For many people, losing weight often feels like an endless battle   between demanding schedules, countless diet trends, and short-lived fitness plans. Yet, for Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford, the real turning point came not from extreme workouts or restrictive diets, but from focusing on one simple thing  gut health.

The Turning Point in Dr. Sethi’s Journey

After years of failed attempts through various diets and workout routines, Dr. Sethi finally discovered a sustainable approach to weight loss. In his October 9 Instagram post, he revealed how he lost 15 kilograms (around 30 pounds) and even reversed his fatty liver   all by making three gut-focused lifestyle changes.

Reflecting on his journey, he shared, “Most people don’t know this, but I’ve lost 30 lbs. For years, I tried everything  diets, long cardio sessions, and strict meal plans   but nothing lasted. It wasn’t until my GI and Hepatology fellowship that I realised I was missing the most important piece: the gut.”

By improving his gut health, Dr. Sethi not only achieved remarkable weight loss but also reversed pre-diabetes, improved his sleep, gained steady energy, and experienced sharper focus  all signs of a truly healthy system.

The 3 Gut Health Changes That Made the Difference

1. From Counting Calories to Counting Ingredients
   Instead of obsessing over calorie numbers, Dr. Sethi shifted his attention to what was actually in his food. He started avoiding hidden sugars, refined oils, and preservatives   focusing instead on whole, natural ingredients that promote gut balance.
   
   

2. From Cutting Carbs to Controlling Sugar Spikes
   Dr. Sethi stopped demonising carbs and began pairing them with fibre, protein, and healthy fats. This helped stabilise his blood sugar levels, reducing sugar cravings and maintaining consistent energy throughout the day.
   
   

3. From Low-Fat Processed Foods to Real, Fibre-Rich Foods
   Instead of relying on “low-fat” packaged foods, he chose real, nutrient-dense, fibre-rich meals   fruits, vegetables, whole grains, and fermented foods   all crucial for a thriving gut microbiome.
   
   

A Lesson for Patients and Practitioners Alike

This transformation didn’t just change Dr. Sethi’s body it changed his entire medical perspective. “I’ve seen the same truth with hundreds of patients: when you fix the gut, you fix the foundation   metabolism, immunity, even brain function,” he explains.

For him, the lesson is clear: lasting health comes from addressing the foundation, not chasing quick fixes.

“In medicine and in life,” Dr. Sethi concludes, “the best results never come from shortcuts; they come from fixing the root cause   and that’s the gut.”
