The book is engaging and fun to read, especially in the first two-thirds. The reviewer appreciates Tim Ferriss's storytelling but finds the latter part less compelling.

Despite this, the reviewer acknowledges the book's entertaining and informative aspects, making it a worthwhile read for those interested in self-improvement and fitness.

skeptical 2.50

The reviewer is skeptical of the book's claims, particularly the rapid fat-loss promises. They find the advice practical but not groundbreaking.

The Harvard Business Review criticizes The 4-Hour Body for its ambitious claims, especially the promise of rapid fat-loss. They argue that while some of the advice is practical and based on scientific principles, it is not revolutionary. The reviewer suggests that the book's approach is more about marketing than providing unique insights, making it less impressive than it claims to be. Overall, they find the book to be more hype than substance.

    Ferriss claims a possible 3% body-fat reduction in a single month by combining the slow-carb diet with just 15 minutes a week of pre-breakfast exercise.

    The book's advice is practical but not groundbreaking.

    The 4-Hour Body is more about marketing than providing unique insights.
