4-Hour Body – Slow Carb Diet
The 4-Hour Body: An Uncommon Guide to Rapid Fat-Loss, Incredible Sex, and Becoming Superhuman is the latest book from Tim Ferriss, #1 New York Times bestselling author of The 4-Hour Work Week.
Tim Ferriss says that 4-Hour Body is the “result of an obsessive quest, spanning more than a decade, to hack the human body. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation.”
Subjects covered include everything from weight loss to sex and just some of the claims made by Tim Ferriss are that you can prevent weight gain while binging, increase fat loss by 300% with a few bags of ice, sleep for two hours a day and feel completely rested and achieve your genetic potential in six months.
4-Hour Body Diet Basics
Tim Ferriss says that by following the diet outlined in The 4-Hour Body you can lose up to 20 pounds in 30 days. The eating plan is described as the “Slow-Carb Diet” and basically involves the intake of lean proteins, legumes and green vegetables.
Five simple rules are presented for dieters who are looking to reduce their level of body fat.
- Avoid “white” carbohydrates. The following foods are to be avoided with the exception of up to 30 minutes after a strength workout: bread, rice (including brown), cereal, potatoes, pasta, tortillas, and fried food with breading.
- Eat the same meals over and over again. According to Tim Ferriss the most successful dieters, regardless of whether their goal is muscle gain or fat-loss, have limited variety in their meals. You can eat as much as you like but you should restrict yourself to three or four meals and repeat them.
- Don’t drink calories. Milk, soft drinks and fruit juice should be avoided. With the exception of red wine, alcohol consumption is not permitted.
- Don’t eat fruit. Says Ferriss, “Humans don’t need fruit six days a week, and they certainly don’t need it year-round. 4-Hour Body says if your ancestors were from Europe, for example, how much fruit did they eat in the winter 500 years ago?”
- Take one day off per week and go nuts. Dramatically increasing your calorie intake once a week increases fat loss by preventing the metabolic slowdown that often occurs with long-term calorie restricted diets.
In addition to dietary recommendations the 4-Hour Body includes information about a range of subjects related to the body. Tim Ferriss suggests that you don’t read the 4-Hour Body from start to finish but instead pick the chapters that interest you and select just one appearance goal and one performance goal to start.

Egg whites, chicken, grass-fed organic beef, pork, fish, lentils, black beans, pinto beans, red beans, soybeans, spinach, asparagus, peas, broccoli, green beans, cauliflower, sauerkraut, tomatoes, avocados, red wine.

Tim Ferriss says that you can lose weight without doing exercise simply by following the “Slow-Carb Diet” but the 4-Hour Body does provide exercise recommendations for both fat loss and muscle gain. Also included is an example of the exercise routine that Ferriss used to gain 34 pounds of muscle in 28 days.
