The diet plan is effective for weight loss, but the author's lack of scientific background should be considered. The book is practical and worth trying, but results may vary.

This reviewer found the diet plan in 'The 4-Hour Body' to be quite effective, losing about 20 pounds in two months. They appreciated the practical advice and found the book useful overall. However, they noted that Tim Ferriss is not a scientist, so some of the methods might not be backed by traditional scientific research. They also mentioned that adherence to the diet was crucial for seeing results. This review suggests that while the book can be helpful, readers should approach it with an open mind and be willing to experiment with the techniques.
