Why We Get Fat and what to Do about it

Readers widely praise this book as a transformative and enlightening read that fundamentally alters their understanding of food, nutrition, and weight loss. Many reviewers reported significant personal success, including substantial weight loss, improved energy levels, mental clarity, and resolution of various health issues like thyroid conditions, low iron, and Type 2 diabetes, often with minimal exercise. The book is lauded for challenging the conventional "calories in, calories out" model, offering a compelling, scientifically-backed alternative centered on the role of carbohydrates and insulin in fat storage. Many found the author's arguments convincing, logical, and thoroughly researched, providing answers to long-standing questions about weight struggles and offering a sense of vindication for those who felt blamed for their weight. It is described as a fascinating and enthralling work of science journalism that provides hope for long-term health and weight management.

However, a notable number of critics expressed strong reservations about the book's tone and methodology. Several reviewers found the author condescending, arrogant, or overly didactic, accusing him of presenting a one-sided argument that functions as an advertisement for low-carb diets. They argue that the book fails to adequately address compelling counterarguments, recent scientific studies, or the proven efficacy of combined diet and exercise approaches. Concerns were also raised about the long-term sustainability and potential health implications of a strict low-carb, high-fat, high-protein regimen, citing issues like boredom, expense, social limitations, and possible strain on organs like the liver and kidneys. Some reviewers, including medical professionals, accused the author of cherry-picking studies to support his conclusions, oversimplifying complex physiology, or even getting the science fundamentally wrong, while others found the book repetitive or overly dense in parts.

Overall, the book presents a provocative and often counterintuitive argument that carbohydrates and insulin are the primary drivers of fat accumulation, rather than simple overeating or lack of exercise, advocating for a low-carb dietary approach. Despite criticisms regarding its tone and potential bias, a significant portion of readers found its insights invaluable and effective for achieving personal health and weight goals. This book is particularly suited for readers who have struggled with conventional weight loss methods, are open to challenging established dietary wisdom, and are interested in a detailed scientific and historical exploration of metabolism and obesity. It appeals to those seeking a long-term, hormone-focused strategy for weight management and the prevention of chronic diseases.
