Anyone read the book? WebMD did a review: http://www.webmd.com/fitness-exercise/features/expert-reviews-timothy-ferriss-4-hour-body
To be honest, it looks like a load of rubbish. What you want is sustained weight loss; losing so much in a short space of time almost always results in piling it back on again not long after. And thus starts the yoyo effect. Regular exercise and a realistic low-fat diet that you can stick to should be the foundation of any good weight loss plan.
Four hours the body is an exciting moment for himself and many other fitness professionals.It provides a hopeful spark to completely change and break many fitness practices, waste of time, and damage our health.
To lose weight are not enough 4 hours of exercise, on the contrary have to be constant for a long time, even to depreciate those 4 hours of spoken, it is best half hour every day of cardio work ... than 4 hours burning and depleting your muscles
2-3 hours day 7 days a week of cardio will do the trick, you just need to cancel the extra food you take, if you intend to eat as usual which could be too much, I think 4 hours might end up being just enough to keep you from gaining weight, nothing more, don't read too much books, just go out
Tim Ferriss is all about the minimum effective dose. I've listened to most of his podcasts, and read the 4 Hour Workweek. These have proved to be an indispensable wealth of of knowledge, when recently starting two businesses. I have not read the 4 Hour Body, but from listening to the podcast you get a basic grasp of some of the concepts contained within it. http://fourhourworkweek.com/podcast/
For me interval kettlebell training has proved best for wait loss, not extended Cardio workouts. Check out this amazing interview. Ways of Training Smart not just Training Hard. Pavel Tsatsouline is interviewed by Tim Ferriss, (the author of the 4Hr Body) Pavel has a few tips that helped me lift more weight in my workouts. http://fourhourworkweek.com/2015/01/15/pavel-tsatsouline/
Just like the 4 hour work week, I don't believe it. You have to work hard for good results - not saying that you can't take away the fact that working smart is important too.
