It’s been fascinating to see how The 4 Hour Body has provoked arguments and disparaging comments in virtually every online fitness community. Typically it looks something like this:
- Original poster: Hey, I am trying Tim Ferriss’s fat loss program in The 4 Hour Body, and I am losing a lot of weight. It’s great. What has been other people’s experiences?
- Response #1: weight loss is a simple matter of calories-in, calories-out. If you want to lose weight, you take in less calories, or put out more calories. I don’t need to spend $14 to learn that.
- Response #2: Who are you to be posting in our community? I’ve never seen you post here before.
- Response #3: What is it with all these people posting about The 4 Hour Body? I think Tim Ferriss must be paying people to go around posting.
- The 4 Hour Body fat loss program doesn’t require restricting food intake. In fact, Tim says, “If you’re hungry, eat more.”
- The 4 Hour Body fat loss program doesn’t require people to spend time exercising, although you can do 2 to 3 minutes of exercises before each meal for more rapid results. But 2 to 3 minutes of exercises does not equal 60 minutes on a stationary bike, or 30 minutes running.
- The 4HB fat loss section emphasizes eating more protein, and no grains, sugars, or fruits. Protein itself has less available calories (3.2/gram) than is normally listed as (4.0/gram), and so it’s already a win over carbohydrates.
- On top of that, the body directly excretes up to 1/3 of excess protein that can’t be used, whereas the equivalent in carbs would be more efficiently converted to fat.
- By ensuring that people eat higher quality foods (protein, legumes, vegetables), they have more energy, and can more easily cut the snacking cycle. This may indeed reduce calories-in greatly, but it’s vastly different than just telling people to “eat less”.
- The use of a high protein diet stimulates metabolism, increasing calories-out without the use of exercise.
- Similarly, cold therapy stimulates metabolism and increases calories-out without the use of exercise.
- GLUT-4 exercises (2-3 minutes of fast paced exercises) redirects incoming calories to muscle development rather than being stored away as fat, a term that Tim calls body recomposition. It is far easier to do and to sustain 2-3 minutes of exercise before a meal compared to taking 60-90 minutes out of your day to “go exercise”, and so most people wouldn’t consider this as exercise per say.
Effectiveness of 4-Hour Body: 28 Days and counting
I started reading the 4-Hour Body by Tim Ferris on Christmas day, and by Monday the 27th, I had started the fat loss program.
If you haven’t read the book, then I’ll try to sum up Tim’s main themes. Calories in and calories out is not the whole equation, he would claim. The kinds of food you eat make a big difference, and there are various hacks you can used to enhance the amount of fat you lose. (Check out my one page cheat sheet if you want to get an idea of what a day looks like.)
Tim says you can lose 20 pounds of fat in 28 days, while gaining 5 pounds of muscle for a net loss of 15 pounds of weight. So 28 days has passed. How did I do?
I lost 13.6 pounds in 28 days, going from 205 to 191.4. I lost 5.5 total inches (sum of circumference of biceps, thighs, hips, and navel). I’m using a bioimpedence scale to measure bodyfat, which is not the most accurate tool, but I did follow Tim’s suggestion of having two glasses of cold water on waking, and measuring 20 minutes later. I only obtained the scale two weeks in. I saw my bodyfat drop 0.8% in two weeks. In sum, I would consider this a good success.
For 4 straight days in week three, due to work stress and other events, I cheated on the diet, and saw myself gain back 2.5 pounds. Had I stuck with it through those days, I believe I would have easily hit the 15-pounds that Tim said would be possible.
Those are the numbers. Now let me give you the experiential perspective:
Week 1:
- I start the fat loss program. The key elements are that I’m not allowed to have any grains or sugars, except on one cheat day per week. (There are other restrictions, such as no dairy, that don’t affect me because I didn’t eat dairy.) Meals consist of a protein source, a legume, and vegetables. I enjoy the food very much (I love beans), but I’m shocked by how much protein I have to eat. It takes about 3 days before I’m eating enough protein for breakfast (target: 30 grams of net protein.) Meals can be as big as I want, and I eat enough to make sure I won’t be hungry before the next meal.
- I find that I really miss my snacks. I find myself in the kitchen at least once every 30 minutes looking for a snack even though I don’t feel hungry.
- It’s hard to stick it out. I concede and allow myself 4 nuts in the afternoon and 4 nuts in the evening as a pure “snack” food. I continue this practice for all 28 days.
- I also continue my practice of having a drink every evening, even though this is not strictly part of the diet.
- I notice that sinus congestion, a chronic condition I am used to dealing with, goes away almost completely, probably due to removing grains from my diet.
- Favorite meal of the week: salmon salad on whole romaine lettuce leaves.
- I go from 205 to a low of 197, then enjoy my cheat day. I pig out, eating an entire tray of honey cookies that could normally feed about 8 people, 2 bowls of ice cream, 4 bowls of potato chips, 3 bowls of pretzels, 2 bowls of nuts, and a large number of chocolate candies.
- I am actually relieved to get back to the diet after making myself slightly sick on cheat day.
- Cravings for snacks continue, although the number of times per day I find myself in the kitchen goes down slightly.
- I am back at work in my office, and find it’s very boring to go through a whole day of work without snacks. I relish in the fact that coffee is still allowed, and even encouraged as it helps fat loss.
- I start GLUT-4 exercises, and enjoy using the Thera-band Latex Exercise Bands.It feels good to be doing something other than just sitting in front of the computer.
- I start using the supplements that Tim recommends.
- I start cold showers this week, another tactic that Tim encourages to help the body burn fat, and start noticing a correlation between high weight loss days and the cold showers.
- I start this week at 200 (I make it a policy not to weigh myself on the day after cheat day), and hit a low of 195.6, a loss of 1.4 pounds over my previous week low.
- Cravings for snacks diminishes this week, and yet strangely this is my hardest week yet. I end up cheating on the diet on 4 consecutive days. All of these behaviors I would attribute to stress. Only one of these is my official cheat day, and the other days I only have “small” snacks: a chocolate candy or a cookie. Yet I see my weight loss completely stall on these days.
- I start the week at 196.2 and hit a low of 193.8, a loss of 1.8 pounds over my previous week low.
- Cravings for snacks is at it’s lowest. I stick to the diet for the whole week. When I have any intense stress related cravings, I get myself a cup of no-calorie chocolate tea, which smells great and is oddly satisfying.
- I start kettlebell exercises.
- I start the week at 196.8 and hit a low of 191.4, a loss of 2.4 pounds of my previous week low. I’ve gone from 205 to 191.4 in 25 days.
10 Tips for Amazon to get the best quality, lowest prices, and free shipping.

Amazon.com is an amazing online retailer that sells far more than just the books and CDs it was once famous for. Now you can shop for anything you could imagine, from computers to food, clothing to furniture.
But there are certain tricks that experienced Amazon shoppers use to find the highest quality items, the best prices, and get free shipping. Without further ado, here they are.
- Sign up for Amazon Prime. Amazon Prime is Amazon’s free shipping program that gives you unlimited free two-day shipping. If you order from Amazon more than six times in a year, this can pay for itself in avoided shipping fees. And once you’re a Prime member, you’ll realize it’s cheaper and more convenient to order from Amazon than make a trip to the corner drugstore, even for routine items like band-aids and shampoo. You’ll save even more money on these every day items, and save the time and gas associated with trips to the store. Not everything sold on Amazon qualifies, because some stuff is sold by third parties. But in general, if it ships from an Amazon warehouse, it’ll ship for free. Prime costs $79/year.
- If you are a parent, check out Amazon Mom. This program gives you the same benefits as Amazon Prime, plus gives you 30% off diapers, all for no up-front charge.
- Choose quality products. With many thousands of products in each department, you want to find the best products within your price range. Thanks to product reviews by other shoppers, you can do this better on Amazon than in a store (are you going to believe a salesperson? or what it says on the box?). Here’s the process to use to find the highest quality items on Amazon.
- Do a search or choose a shopping category to get started. For example, I recently was looking for a “CD radio”
If you did a search, choose a department from the left hand column to enable sorting.
- Usually you want the department with the highest volume of matches, or the ones most relevant to your search. The search results themselves show you how many matches exist in a given department. Note the “Electronics: See all 5,442 items” in the photo below.
- Once you’re in the right department, choose “Eligible for Amazon Prime” in the left hand column, or eligible for free super-saver shipping, if not a Prime member.
Also in the left hand column, choose Avg Customer Review of 4 Stars or more, the top line. With thousands of matching products, there’s no reason to look at items with less than a 4-star rating. Many products will have dozens or hundreds of reviews. To achieve a 3 star or lower rating, a product has to be pretty bad.
- Now begin looking at the search results. You should have limited those results to high quality, free shipping items. It’s time to find the product that best matches the features you’re looking for. You shouldn’t pay for more product than you need. For example, I was looking for a CD player for my kid’s bedroom. I didn’t want to spent $75 or even $200 for a five year old’s radio. You can use the price limiters to set the price range you are willing to consider.
- Then look at the individual products, keeping three things in mind:
- A five star rating is meaningless if it is based on 1 or 2 reviews. Look at other products, and get an idea of how many reviews products in that category seem to have. If they have 50 or more reviews, then a product with only 1 or 2 reviews is suspect, even if those reviews are glowing. (Perhaps they are from the manufacturer themselves?)
- Look at the individual reviews to see what customers are saying, both positive and negative about the product. For example, I ended up a choosing a NAXA CD Radio. It was rated 4 stars, but virtually all of the negative reviews complained that the radio didn’t get loud enough. And that was pretty much the only complaint. Well, since I was choosing this for my kids room, and since I didn’t want them blasting their radio, that “negative” was actually a positive for me. It took a 4 star product and made it a 5 star product for me.
- If you can find something with 50 or more reviews and a 4.5 star or higher rating, you can be pretty confident that it is a great quality product you’ll be happy with.
- Buy groceries in bulk online: Amazon’s grocery store is like an online Costco, where you can get foods for about 10-20% less than you’d find them in the grocery store. This is great for items you eat on a regular basis, like cereal, bread, canned goods, and more. They have over 5,000 gluten-free items, more than 22,000 organic items.
- Use the Subscribe and Save
program to save an additional 15% on items you use all the time, like coffee, toilet paper, diapers, and so on. Plus, because the delivery of the items can be scheduled, you won’t run short and need to make a last minute run to the grocery store. Between the discounted prices and the Subscribe and Save program, you could be saving 25% or more on the items you use most often.
- Use the Amazon Credit Card
, and get 3% back on anything you buy from Amazon, 2% back at gas stations, restaurants, and drug stores, and 1% back on anything from any other retailer.
- If you don’t have Amazon Prime, and you need to spend just a little more money to qualify for free super-saver shipping, use filleritem to find inexpensive items to add to your shopping cart.
- Use the mobile apps, Amazon iPhone app
or Amazon iPhone app
to check out products when shopping at local retailers. You can use Amazon’s product reviews to see what other customers thought, and check to see if the price is cheaper online. And if you’re undecided on whether to buy it, you can put it in your Amazon shopping cart, and do more research later. Too often I’ve made impulse buys at local stores only to regret it later, thinking “if only I had researched it on Amazon first.” Now you can research products on the fly.
- Learn to Return
: It’s very easy to return products to Amazon. If an item doesn’t work, isn’t compatible, or isn’t what you ordered, Amazon will pay for return shipping. For anything else, you pay for shipping, but Amazon makes it easy by printing the shipping label for you, and just deducting the shipping costs from your credit. And “compatible” can be broadly interpreted. For example, I received a pan that didn’t fit in my dishwasher. To me, that meant it wasn’t compatible with my kitchen. So Amazon picked up the return shipping charge. I think it’s much easier to return something with Amazon than with a typical store. There’s no need to confront a manager, or wait in line at a return counter. Just go online, and 5 minutes later you’re done. Then drop off the package at any shipment location.

That’s it for the basic tips. You should be:
- Saving 3% across the board from the credit card.
- Saving 5-10% in free and reduced shipping charges.
- Saving 10-25% on groceries.
- Getting better quality products that last longer and give you more satisfaction.
- Saving time and money on items that become more convenient to purchase from Amazon than making a trip to chain drugstores and malls.
Advanced Tips:
Ready to go beyond the basic tips?
- Search for discounted products: You can search a given department to find only discount products. For example, if you wanted to look up discounted LCD TVs, you would go first to the LCD TV department
. Then go to the url bar in your browser, and add the text &pct-off=50- Hit return, and the page will refresh to show you only the TVs that are 50% off. You can replace 50 with whatever percent off you’d like to look for.
- Amazon Movers and Shakers
is an Amazon page that lists those products that are rapidly rising in sales rank. Frequently these are new products that are just starting to be sold on Amazon, but sometimes they can be products that have a deeply discounted price.

How to Take a Cold Shower
- 4-Hour Body Shopping List (including supplements)
- 4-Hour Body Cheat Sheet
- Slow Carb Meal Plan
- How To Do Kettlebell Swing (demo by Tim Ferris)
If you’ve been reading the 4-Hour Body, then you probably know that one of the techniques that can help you lose fat faster is to take cold showers. Cold showers burn fat in several ways:
- They stimulate your brown fat cells, helping the ones you have reproduce, work harder
- They cause your body to compensate for the loss of body heat through shivering and a higher metabolic rate.
- They can help reduce or avoid depression.
- Improves circulation, which is good for overall cardiac health.
- Strengthens your immune system
- Increases testosterone and fertility.
- Start with a normal, hot shower.
- Shampoo your hair and rinse normally.
- Soap up in the hot water.
- Then, turn the temperature to a low luke-warm. Nothing that you’d identify as cold, just neither cold nor warm.
- Rinse off in this low luke-warm water. This gives your body time to adjust to the temperature.
- Now, turn your back to the water.
- Turn the temperature down slightly, just a few degrees cooler.
- Wait about 30-40 seconds. You can count off one-one thousand, two-one thousand, or you can sing the ABCs.
- Repeat 7 and 8, as many times as you can. I can now go about 6 cycles of gradually reducing the temperature.
- I usually stop the cycle after my teeth start chattering while singing the ABCs.
- You still get to enjoy a hot shower to start.
- You gradually reduce the temperature so that it is never an unpleasant shock.
- By the time the water temperature is getting really cold, your upper back and neck are already somewhat numb, so you hardly notice the temperature change.
- Using this method, you should easily be able to spend 5-6 minutes in an increasingly cold shower.

When getting started with the The 4-Hour Body fat loss program, which uses the slow-carb diet, you may be wondering what exactly to cook. Tim Ferris gives some great examples of single meals in the book, but they still may leave you wondering what a week of cooking would look like.
Here’s an example meal plan, based on what I ate for a week while doing the fat loss section of the 4 Hour Body. It’s just an example, based on what I like, but I think it holds true to the principles that Tim describes:

4 Hour Body Slow Carb Example Meal Plan |
- Keep it simple, repeat meals over and over.
- Protein, legumes, and vegetables with every meal.
- At least 30 grams of protein at breakfast, and 20 grams at lunch and dinner.

If you’ve been wondering how to do the kettlebell swing that Tim Ferris describes in the 4 Hour Body, in the section entitled “Perfect Posterior”, here is a video of Tim Ferris explaining exactly how to do it.
Tim recommends a 20kb/44lb or 24kg/53lb kettlebell for men to start, and a 16kg/35lb or 20kb/44lb kettlebell for women to start. I was pretty out of shape, and I started with a mere 20lb kettlebell. (You can find kettlebells on Amazon.)

If you’re reading the The 4-Hour Body by Tim Ferriss, you’re probably making a list of all the things you want to buy. I went through that over the last two weeks, so I put together a consolidated shopping list.
I’m partial to shopping at Amazon for pretty much everything, so links are to the products or closest equivalents that Tim recommends in Four Hour Body on Amazon. Prices were accurate at the time posted.
- Measurements:
- MyoTape Body Tape Measure
($6.45, equivalent to OrbiTape one handed tape measure.)
- Escali Bio Impendence Scale
($44.95, exact scale recommended by Tim.)
- Slim Guide Skinfold Caliper
($15.65, exact caliper recommended by Tim. Not required to buy both caliper and scale.)
- MyoTape Body Tape Measure
- Supplements
- Supercissus Rx Capsules
($26.99, cissus quadrangularis, for use on binge days and periodic supplementation, but not indefinite daily use.)
- Policosanol 23mg, 60 tablets
($24.99, free shipping, part of PAGG)
- Vitamin Shoppe – Alpha-Lipoic Acid, 300 mg

($13.50, 99 cent shipping, part of PAGG. Aged garlic.)
- Exercise Equipment
- Thera-band Latex Exercise Bands
($~4.22, free shipping. These are the elastic bands that Tim uses for chest-pulls, the GLUT-4 releasing exercise. Strength varies by color. Small enough to carry in pants pocket.)
- First Place Kettlebells ($60-150. There are many, many kettlebell manufacturers and sellers. This is one 5-star rated kettlebell that is available in a variety of weights. Tim recommends a 20kb/44lb or 24kg/53lb kettlebell for men to start, and a 16kg/35lb or 20kb/44lb kettlebell for women to start. Here’s a second link if you need a wide range of weights: First Place Vinyl Kettlebells
.
- Update 1/23/2011: I like these no-frills 4.5 star rated Kettlebells that ship free from Amazon: Body-Solid Kettlebells
Also, check out my post on the fat loss cheat sheet, if you’d like to have a simple daily schedule. If you like the cheat sheet, you may also enjoy Slow Carb Fat Loss, a companion book that puts together the cheat sheet, a meal plan, and helpful tips to the Slow Carb diet.
A reminder: none of this stuff makes sense unless you are buying and following the 4-Hour Body. It’s a great book, well researched and entertaining.
P.S. One other item people have been having a hard time finding is the vitamin rich butter, fermented cod liver oil combination recommended by Tim Ferriss. It’s not in the fat loss section, but I thought I’d list it here since so many people are looking for it. Blue Ice Royal Butter Oil / Fermented Cod Liver Oil Blend – Capsules is rich in Vitamin K and Vitamin D. Green Pastures is the only supplier of it. They are a family owned farm.

If you have been reading The 4-Hour Body by Tim Ferris, you’re probably pretty excited to get started. Although the basic eating plan is simple enough, if you add in the GLUT-4 exercises, supplements, and other activities, it can get confusing to plan your day.
I did my best to capture the eating plan, GLUT-4 exercises, supplements, and cold therapy in one cheat sheet for my own use, which provides a daily schedule for the 4-Hour Body fat loss plan.
It is not a replacement for the book itself. The 4-Hour Body is an excellent resource, well researched and carefully documented. The cheat sheet is just a helpful way to capture the most important information on a single page for people who have read the book.

Process for Pitching an Idea to a Publisher
I was recently asked “What is the process for pitching an idea to a publisher?”
Although I am far from an expert, I am going through the process now of submitting my manuscript to publishers and agents, and so this was my reply:
Chrome OS Cr-48 Week 2 Review
I’ve had my Google CR-48, the reference implementation notebook for Chrome OS, for a week and a half now. You can read my earlier reviews here and here.
