Perfect for you if...

You've hit a weight loss plateau with calorie counting and want to understand the metabolic mechanisms that actually unlock fat loss.
You're curious about fasting but unsure where to start, and need a practical roadmap for intermittent, alternate-day, or longer fasts.
You're drawn to ancestral health practices and want evidence-based explanations for why your ancestors fasted and what that means for your body today.

Maybe not for you if...

You have a history of disordered eating or struggle with food restriction, as this book focuses on extended periods without eating.
You're looking for a quick-fix diet hack rather than understanding the deeper physiology of how fasting reshapes your metabolism.
You prefer nutrition advice backed by only the latest trendy studies rather than established medical science and case studies.

About this book

While numerous books address weight loss and health through various diets, a fundamental component of successful nutritional health programs is often overlooked: fasting. This ancient practice forms the focus of The Complete Guide to Fasting, where Jason Fung and health podcaster Jimmy Moore explain what fasting is, why it matters, and how to practice it effectively for health improvement. The book covers intermittent, alternate-day, and extended fasting approaches, providing guidance on implementing these methods as part of a health program.
