4G Code to Good Health: Knowing What to Eat and What Not To—The Power Lies with You

The book moves beyond conventional dieting and focuses on understanding how the body responds to food. Ishi Khosla combines scientific knowledge with traditional wisdom to explain how nutrition can influence appetite, cravings, mood, sleep, weight and immunity.

The book encourages readers to understand their individual nutritional needs rather than blindly following restrictive diets.

Ishi Khosla is a practising clinical nutritionist, consultant, columnist, researcher, writer and entrepreneur. She began her career at the All India Institute of Medical Sciences and later headed the Nutrition Department of Preventive Cardiology at Escorts Heart Institute and Research Centre. She also founded Whole Foods India and the Celiac Society for Delhi.

4G Code to Good Health presents a simple framework for understanding better health through four interconnected areas: Gut, Girth, Gluten and Glucose. The author explains how what we eat, digest and avoid can influence our physical and emotional well-being.

Rather than promoting short-term dieting, the book encourages sustainable changes in eating and lifestyle. It aims to help readers understand their bodies, manage food choices more effectively and develop habits that can support long-term health.
