Written by Dr. Avinash Tank — MCh Surgical Gastroenterology, SGPGIMS
Obesity is not a failure of willpower. It is biology — and biology can be understood.
Most people who struggle with weight have already tried. They have counted, fasted, walked, restarted on a Monday and blamed themselves when it came back. What almost nobody explains is why it came back — that hunger, storage and metabolism are run by hormones, and that those hormones fight to restore the weight you lost.
This book starts there. It explains what is actually happening inside your body, why the standard advice fails so reliably, and what genuinely works — nutrition, sleep, stress and habit change first, then medication, endoscopic options and surgery when they are the right answer. No shame, no miracle claims, and no product to sell you at the end of a chapter.
It is written by the surgeon who performs these operations, in the language he uses in consultation.

On the author
What patients say about Dr. Tank
These are patient testimonials about treatment, not book reviews. Reader reviews appear here once the book sells online.
Dr. Tank explained everything clearly and never rushed. My gallbladder surgery was smooth and I was home the next day. Truly patient-first care.
After years of acidity, the laparoscopic surgery finally fixed it. Honest advice, no pressure, excellent result.A colonoscopy caught a polyp early. Calm, reassuring and thorough — I am grateful for the careful approach.

Yes — request one when you order directly from the clinic and Dr. Tank will sign it before it is sent or collected.
No. It is written for patients and families in plain language. Medical terms are explained the first time they appear, and no chapter assumes clinical training.
No. Surgery is one part of the final section. Most of the book is about understanding obesity and the non-surgical routes — nutrition, habits, sleep, stress and medication.
Yes, a digital edition is part of the release. Message the clinic if you would like to be told the moment the listing is live.
No. It helps you have a far better-informed conversation with your surgeon, but it is educational and is not a substitute for a personal medical assessment.
