I’m a fan of periodic experiments for finding new ways to improve your mind and body.  My latest experiment is shedding ten years of age-related damage in ten weeks based on the book, Shed 10 Years in 10 Weeks, by Dr. Julian Whitaker and Carol Colman.  Given how much heart disease, cancer, … etc there is in today’s world, it won’t hurt me to put more techniques under my belt.  I told some friends and colleagues about my experiment and they wanted me to share my notes, so here it goes …

Benefits of the Age-Loss Program
The book outlines the following potential benefits:

• Lose a decade’s worth of fat and regain ten year’s worth of muscle.
• Erase fine lines, diminish wrinkles, and restore youthful glow.
• Boost your brain power and sharpen your memory.
• Revitalize and enjoy your sex life.
• Strengthen your immune system and prevent disease.
• Recharge your spirit and regain your energy of yesteryear.

The Key to the Age-Loss Program
What I like about the book is that it’s not magic.  It’s based on results from research and experience with more than 15,000 patients.  It boils down to the following formula — eat the right foods, take the right supplements, exercise regularly, and control the negative impact of stress in your life.  Dr. Whitaker does mention that the combination of supplements is especially important.

Wellness and Reversing Diseases
I really like the fact that Dr. Whitaker is focused on wellness over illness.  He specializes in modeling from the best and sharing what works.  I also like the fact that he focuses on “reversing” issues.  For example, he has books on reversing diabetes, reversing heart disease, and reversing health risks.

10 Steps of the Age-Loss Program
Here’s a summary of the objectives of the ten steps, according to Dr. Whitaker and Colman.

Supplement Routine
Here’s an example of the supplement routine, based on Dr. Whitaker’s and Colman:

Results So far
I’m only three weeks in so I don’t expect miracles.  So far though I’ve dropped more than 10 pounds and I’m closer to my “fighting weight.”  I have a lot more power hours throughout the day.  I have a spring in my step and I feel a lot more powerful.  I would expect that from any combination of the right foods, the right workout, and the right sleep.  I guess the part that’s different is how quickly my nails and hair are growing and how fresh my skin is.  I think that’s where the supplements are showing.

Lessons Learned
I’ve learned a few lessons so far that really help me:

• Reduce friction.  Rather than depend on sheer will power, I find ways to make it easier to fall into success.  trade complexity for simplicity.  Anything I can do to simplify or reduce friction, I do.  For example, rather than run outdoors, I got a NordicTrack Elliptical so that rainy days didn’t get in the way.
• Find the fun.  I think anything long-term has to be fun.  In general, we move towards pleasure and away from pain.  For example, I originally was going to get a treadmill, but realized that I liked the idea of bounding on an Elliptical better.  I also found that I need to play my favorite songs to associate fun to the pain of the workout.
• Take weekends off.  I doubt Dr. Whitaker would agree, but for me, it’s easier for me to push during the week, if the weekend is playtime.
•  Make it a routine.  I found that I really have to make it a routine so the less I have to think about it, the easier it is to just do it.  For example, even just scheduling time for the workout was important.  I tested in the morning and tested at night, and while the morning is easier to make a routine, I find I like it more at night.
• Find your personal success patterns.  I experimented with a few different sleep patterns and found that if I wake up too early, I’m just no my most for the day.  I really do measure my day in power hours.  What good is having more time if you can’t use it?  I finally realized that just by flipping through my past experiences, I could find success patterns that worked to draw from.
• Turn your routines into checklists.  I find that having a simple, scannable checklists go a long way (for example, the supplement routine, skin routine, and workout routine above helped me quickly visualize what I need to do.)
• Find what works for you.  I found the diet part of the routine a little tough to follow.  I think the principles were sound, but it’s easier for me to just follow The Zone.  (see A Zone Primer.)

Do you feel smarter after you workout?  It’s because you have more oxygen available to your brain.  Working out also increases your sense of well-being.  In Shed 10 Years in 10 Weeks, Dr. Julian Whitaker and Colman write about how exercising makes you smarter and feel better.

Think Better and Feel Better
Dr. Whitaker and Colman write the following:

Did you ever wonder why you feel so recharged after a good workout?  Nowhere is the body mind connection more apparent than when it comes to the effect of exercise on the brain.  Exercise increases the amount of oxygen available to the brain by making the heart stronger and able to pump more oxygenated blood.  In addition to increasing oxygen stores, exercise creates a natural high.  It stimulates the release of endorphins, neurochemicals that actually have an opiatelike effect on the brain.  People who exercise think more clearly, feel more alert and energetic, and have a markedly increased sense of well-being.

Key Take Aways
Here’s my key take aways:

• Exercising makes you think and feel better and act better.
• You feel smarter after you workout because you have more oxygen available to your brain.
• Endorphins released during exercise make you feel better.

I originally thought the Zone was a fad diet, but a colleague told me that it’s actually based on science and results.  In fact, some Olympic athletes have used the Zone.  I then started researching the Zone to find patterns and practices for more effective eating strategies.  In this post, I summarize fundamentals of the Zone.  This post is based on the book,  The Top 100 Zone Foods: The Zone Food Science Ranking System, by Dr. Barry Sears.

You’re Only as Good or Bad as Your Last Meal
According to Dr. Sears, your hormones are adjusted at every meal:

To enter the Zone, you need to learn how to maintain the hormones produced by the foods you eat within a Zone (not too high, not too low).  These hormones are readjusted every time you eat a meal or snack, so you’re only as good or as bad as your last meal.  This means that if you splurge and eat too many carbohydrates in one sitting, you can get back into the Zone the next time you eat.  Thus you don’t need to feel guilty about cheating.  Just make your next meal Zone-friendly.

The Zone is a Precise Medical Definition
Dr. Sears writes that the Zone is a precise medical definition:

The Zone is not some clever marketing phrase.  The Zone has a very precise medical definition that can be measured with a simple blood test.  The next time you have a blood test, ask your doctor to measure your fasting insulin levels.  If your insulin levels are too high (greater than 10 uU/ml), you know that you’re not in the Zone.  The sluggishness, hunger, and moodiness you feel in between meals are all signs that you’re out of the Zone.

Food is Your Key Drug
According to Dr. Sears, food is your key drug for controlling your insulin:

You can lower your insulin levels to get into the Zone.  The only “drug” that can take you there is food.  In the process, you’ll radically improve your quality of life.  You’ll feel less tired, more mentally charged, and happier throughout the day.  Your new hormonal balance will be giving your body the continuous fuel it needs to keep all your systems operating at their peak performance.  You will feel your body tell you that “all systems are go” and that the possibilities of what you can do are limitless.

Wipe Away the Myths
Dr. Sears writes that you have to reexamine what you know about nutrition:

How can you gain control of your unruly hormones?  You need to wipe away many of the nutrition myths that you’ve probably come to believe — for example, that fat is bad and pasta is good.  You need to stop fooling yourself into thinking that you can lose weight while eating fat-free cookies or fat-free ice cream.

Balance and Quality
Dr. Sears writes that the key to the Zone is balancing protein, carbs, and fats and choosing higher quality foods:

You need to embrace the notion that you must have a balance of the three major categories of food (protein, carbohydrates, and fat) at every meal to get the right response from your body.  You also need to be selective about the quality of the foods you choose within each category to get the most hormonal cluck for your buck. …  Get the right balance and quality of foods, and your body will produce the appropriate hormonal signals for the next four to six hours.  During this time, you will be in the Zone.  You can keep yourself there by eating the same balance of foods at your next meal or snack.  But you still need to be selective about the quality of foods you choose within each category.

Seven Rules of the Zone
Dr. Sears provides seven rules for the Zone:

• Rule 1.  Always eat a Zone meal within one hour of waking.
• Rule 2.  Every time you eat, go for a Zone balance of protein, carbohydrates, and fat.
• Rule 3.  Try to eat five times a day: three Zone meals and two Zone snacks.  Afternoon and late evening snacks (which are really Zone mini-meals) are important to keep you in the zone throughout the day.
• Rule 4.  Never let more than five hours go by without eating a Zone meal or snack — regardless of whether you are hungry or not.  In fact, the best time to eat is when you aren’t hungry because that means you have stabilized your insuline levels.
• Rule 5.  Eat more fruits and vegetables (yest, these are carbohydrates) and ease off the bread, pasta, grains, and other starches.  Treat these low-quality carbohydrates like condiments.
• Rule 6.  Drink at least eight 8-ounce glasses of water every day.
• Rule 7.  If you make a mistake at a meal, don’t worry about it.  There’s no guilt in the Zone.  Just make your next meal a Zone meal to get you where you (and your hormones) belong.

Divide Your Plate in Three (The Hand-Eye Method)
Dr. Sears provides a simple way to divide your plate to create a Zone friendly meal:

Divide your plate into three portions.  On one-third of your plate, choose a low-fat protein portion.  It should be no bigger than the size and thickness of your palm.  Then fill the other two-thirds of your plate with high-quality carbohydrates (vegetables and fruits).  Add a dash (that’s a small amount) of “good” fat to complete your Zone plate.

Zone Food Block method
For those that want a more precise way of measuring your meal, Dr. Sears provides the Zone Food Block method:

You may find that creating Zone meals using the hand-eye method described earlier works well to get you into the Zone.  Some people don’t like to estimate portion sizes, however, and would prefer a more scientific way of measuring out carbohydrates, protein, and fat.  If you are one of these people, you should consider using the Zone Food Block method.  … Instead of using your plate as a guide, you’ll be counting out blocks of protein, carbohydrates and fat. 

Protein Block, Carbohydrate Block, and Fat Block
According to Dr. Sears, the Zone Food Blocks are as follows:

• Protein Block.  One Protein Block contains 7 grams of protein.  The average male needs four Protein Blocks and the average woman needs three Protein blocks.  
• Carbohydrate Block.  One Carbohydrate Block contains 9 grams of carbohydrates.  3 Carbohydrate Blocks would contain 27 carbohydrates.  4 Carbohydrate Blocks would contain 36 carbohydrates.
• Fat Block.  One Fat Block contains 3 grams of fat.  3 Fat Blocks would contain 9 grams of fat.  4 Fat Blocks would contain 12 grams of fat.

Key notes about the Zone Food Blocks:

• The number of Protein Blocks you need depends on whether you are a man or a woman.
• Eat the same number of Carbohydrate Blocks at every meal as Protein Blocks.
• Eat the same number of Fat Blocks at every meal as Protein Blocks.

The “1-2-3″ Method
Dr. Sears writes that you can think of the Fat Block as the “1-2-3″ Method:

Each fat block contains 3 grams of fat, so you’ll get 9 grams of fat in three blocks and 12 grams in four blocks.  Another way to think of this is to use the “1-2-3″ method.  Plan to have 1 gram of fat for every 2 grams of protein and 3 grams of carbohydrate.  A typical Zone meal for a woman would contain 10 grams of fat, 20 grams of protein, and 30 grams of carbohydrate.

The Average Woman Zone Food Blocks
According to Dr. Sears, a typical Zone meal for a woman would contain about 9 grams of fat, 21 grams of protein, and 27 grams of carbohydrates.

• 3 Protein Blocks.  The average woman will need three Protein Blocks for each meal (21 grams of protein.)  That translates into about 3 ounces of high-quality protein.
• 3 Carbohydrate Blocks.  The average woman will need three Carbohydrate blocks for each meal (27 grams of carbohydrates.)
• 3 Fat Blocks.  The average woman will need three Fat Blocks (9 grams of fat.)

The Average Male Zone Food Blocks
According to Dr. Sears, the typical Zone meal for a man would contain about 12 grams of fat, 28 grams of protein, and 36 grams of carbohydrates.

• 4 Protein Blocks.  The average man will need four Protein Blocks for each meal (28 grams of protein.)  That translates into about 4 ounces of high-quality protein.
• 4 Carbohydrate Blocks.  The average man will need four Carbohydrate Blocks for each meal (36 grams of carbohydrates.)
• 4 Fat Blocks.  The average man will need four Fat Blocks for each meal (12 grams of fat.)

Three Steps to a Zone Meal
Dr. Sears outlines the three steps to a Zone meal:

• Step #1. Start with Protein
• Step #2. Balance with Carbohydrates
• Step #3. Add Fat

Step #1.  Start with Protein
Dr. Sears writes:

The first step of Zone meal preparation is never to consume any more low-fat protein than you can fit in the palm of your hand or that is any thicker than your hand.  For the average American female, this amount is 3 ounces of low-fat protein, and for the average American male it is about 4 ounces.  Unless you are active, your body can’t utilize any more protein that that at a single sitting, and any excess protein will be converted to fat.

Your body needs a constant supply of dietary protein to replace the protein that is lost from your body on a daily basis.  What’s more, eating protein stimulates the release of the hormone glucagon, which has a hormonal effect opposite to that of insulin.  Glucagon tells your body to release stored carbohydrates from the liver to replenish blood sugar levels in the brain.  Without adequate levels of glucagon, you’ll always feel hungry and mentally fatigued because your brain is short on its primary fuel — blood sugar.

Step #2. Balance with Carbohydrates
Dr. Sears writes:

Once you have the protein portion of your meal, you need to balance it with carbohydrates.  Remember: fruits and vegetables are carbohydrates.  In fact, they are the highest-quality carbohydrates you can eat, which is why (with one or two exceptions) they are the only carbohydrates you’ll find on my Top 100 list.  The reason you won’t find pasta, rice, or mashed potatoes on my list is that they wreak havoc on your body without providing much nutrition.  First of all, these carbohydrates  in cause dangerous spikes in your insulin levels, which cause your blood sugar levels to rise and then quickly fall, leaving you famished just two hours after eating.  Second, these carbohydrates contain very few vitamins and minerals (unless they’re artificially fortified) and only sparse amounts of phytochemicals, the tiny plant chemicals that can ward off cancer, heart disease, and other illnesses by acting as powerful anti-oxidants.

On the other hand, fruits and vegetables meet both of my criteria for high-quality foods.  They are packed with natural vitamins, minerals, and phytochemicals.  They also contain fiber, which slows the release of insulin so you won’t get quick spikes in your blood sugar.  This is why an apple leaves you feeling satisfied longer than a cookie.  not all carbohydrates are equal in their ability to stimulate the production of insulin.  The high-quality carbohydrates are favorable in that they have the capacity to stimulate insulin: others are unfavorable in that they have a high capacity to stimulate insulin.

Step #3: Add Fat
Dr. Sears writes:

Now your plate is completely covered.  Protein takes up one-third of the space, and carbohydrates take up the other two-thirds.  Where does fat fit in?  Fat is the sprinkling that seasons your foods — whether it’s the teaspoon of olive oil that you cook your vegetables in or the avocado slices or handful of slivered almonds that you add to your salad.  Without fat, you can’t have a complete Zone meal.

Fat has no direct effect on insulin, nor does it have any effect on glucagon.  Fat, though, acts like a control rod in a nuclear reactor, slowing the rate at which carbohydrates enter your bloodstream.  In addition, it also causes the release of another hormone that tells your brain to stop eating.  Finally, fat gives you a feeling of satiety and helps blend the flavors that give great meals their exquisite taste.

The high-quality fats that make my Top 100 list are those that are good for your heat and your health in general.  These are the monounsaturated fats and long-chain Omega 3 fats.  You get monounsaturated fats from olive oil, select nuts, and avocados.  Long-chain Omega-3 fats come from fish and fish oils (like the cod liver oil your grandmother told you to take).  These are exceptionally powerful allies in your quest for a longer life.

The fats that are absent from my Top 100 are the saturated fats, trans fats, and Omega-6 fats.  You find saturated fats in margarine and other partially hydrogenated oils found in many processed snack foods.  Polyunsaturated fats like corn and safflower oil are rich in Omega-6 fats, which in excess are far worse for you hormonally than saturated fats.  I consider these Omega-6 fats to be really “bad” fats because they can lead to increased inflammation, which is an underlying cause of heart disease and arthritis.

Zone Meal Timing
Dr. Sears provides an example of meal timing to stay in the Zone throughout your day:

A Day in the Zone
Dr. Sears provides an example day in the Zone:

You’ll Lose Weight and Live a Longer Life
Dr. Sears writes:

Just glancing through this, you should notice that it’s a lot of food.  That’s because you’re eating low-density carbohydrates in the form of fruits and vegetables.  On a volume basis, fruits and vegetables contain much fewer carbohydrates than high-density bread and pasta.  This means you get more food in fewer calories.  For this reason, women typically eat only about 1,200 calories a day on the zone and mean only about 1,500 calories per day.  This is what I call the Zone paradox.  You can consume a lot of food without getting a lot of calories or feeling hungry or deprived.  You will also lose weight, which is an added plus.  Most importantly, if you eat only Zone meals and snacks, you are greatly increasing your chance for a longer life by keeping your overall calorie count at a level that has been shown by 60 years of research to be the only way to reach your maximum longevity.

Key Take Aways
Here’s my key take aways:

• You’re only as good or bad as your last meal.  I really like this idea of eating thinking one meal at a time.  Your hormones readjust every time you eat, so each meal is a new chance for you to get in the Zone.
• Your insulin levels influence your quality of life.  Your hormones influence your thinking and feeling.  They also influence your ability to have a long and healthy life.
• Food is the key drug that controls your insulin levels.  Your food choices impact your insulin.
• The key to the Zone is balancing carbohydrates, proteins and fats.  To be in the Zone, you need to balance your carbohydrates, protein and fats. 
• Choose higher-quality foods over lower-quality foods.  You need to choose higher-quality foods over lower-quality.  For example, choose fibrous carbohydrates over starchy carbohydrates.  Avoid foods that have a high glycemic impact.
• For a Zone meal, divide your plate in three.  For 1/3rd of your plate, choose a low-fat protein (chicken or fish.)  For 2/3rds of your plate, choose fibrous carbohydrates (fruits and vegetables.)
• Think in protein, carbohydrate, and fat blocks.  A Protein Block is 7 grams of protein, a Carbohydrate Block is 9 grams of carbohydrates, and a Fat Block is 3 grams of fat.
• Men need 4 blocks of protein, carbohydrates, and fat.   This translates to 12 grams of fat, 28 grams of protein, and 36 grams of carbohydrates.
• Women need 3 blocks of protein, carbohydrates, and fat.  This translates to 9 grams of fat, 21 grams of protein, and 27 grams of carbohydrates.
• Choose “good” fats over ‘bad” fats.  Choose monosaturated fats and long-chain Omega 3 fats over saturated fats, trans fats, and Omega-6 fats.

The Story of the Zone
Dr. Sears writes about his inspiration for creating the Zone:

You probably assume you’re a product of your genes.  You have your father’s eyes, your mother’s freckles, and your grandmother’s diabetes.  I, too, am a product of my genes.  Every male on my father’s side has died at an early death after suffering a premature heart attack.  My father died in 1972 at the age of 54, and I was sure that I was genetically destined for this same fate.

 Although I knew I couldn’t change my genes, I didn’t want to be a slave to them either.  I was determined to alter my genetic destiny and live a normal, healthy lifespan.  I didn’t buy into the notion that some new medication would come along to save me.  I had to take charge of my own health directly by changing my eating habits.  So I decided to devote my work as a researcher to discovering what, if any, dietary habits could reverse my impending collision course with my genetic fate.  Through 20 years of research, I’ve learned that foods can indirectly turn certain genes on and off by altering the levels of hormones, the chemical messengers that control our lives.  These hormones can alter our genetic fate by increasing or decreasing our natural lifespan.

 

Keep Your Insulin Levels in the Zone
Dr. Sears writes that the key to a longer, healthier life is controlling your insulin levels:

One of the most powerful hormones controlled by foods we eat is insulin.  My research found that if you could keep insulin levels within a certain zone — not too high and not too low — you could, in fact, bypass your genetic glitches and avoid certain chronic diseases.  The result?  A longer and healthier life.

A Life-Long Dietary Strategy
Dr. Sears writes that the Zone is not a short-term diet, but a life-long dietary strategy:

I called my program the Zone Diet.  Although it was developed for treating cardiovascular disease and Type 2 diabetes, it is also the most effective way to lose excess body fat without feeling deprived or hungry.  It is not a short-term diet, but a life-long dietary strategy that can keep you at a healthy weight for the rest of your life.

Carbohydrates, Protein and Fat 
Dr. Sears writes that the key to the Zone is balancing carbohydrates, protein and fat:

All you need to do is eat the right combination of foods at every meal.  This means eating a balanced amount of carbohydrates, protein and fat at every meal and snack — and eating all these foods in moderation.  Follow this simple rule at every meal, and you will achieve the hormonal responses that will get you into the Zone.

The Longest Living Population in the World
According to Dr. Sears, the Okinawans have a diet similar to the Zone:

The Zone Diet has continued to evolve into increasingly healthier versions, such as replacing low-fat animal protein with increasing amounts of soy protein. I wrote The Soy zone based on the diet eaten by the longest-living population in the world, the Okinawans.  Their basic diet is the Zone Diet, containing primarily vegetables, some fish and animal protein, but with most of their protein from soy.

Short Term Benefits in the Zone
According to Dr. Sears, within one week of the Zone, you’ll enjoy the following benefits:

• Get mentally focused.
• Experience a surge of energy.
• Lose a few pounds of fat.
• Feel happier.
• Gain control over your insulin levels.

Long Term Benefits in the Zone
According to Dr. Sears, in the longer term, the benefits of the Zone include:

• You will achieve permanent fat loss.
• You will reduce your risk of heart disease.
• You will protect yourself against adult-onset (Type 2) diabetes.
• You will lower your risk of arthritis and osteoporosis.
• You may reduce your risk of developing breast cancer.
• You’ll get fewer infections.
• Your skin will look younger.

Key Take Aways
Here’s my key take aways:

• The Zone was originally created for cardiovascular disease and Type 2 diabetes.
• The longest-living population follows  diet similar to the Zone.
• You can successfully influence your genetic tendencies by your food choices.
• Treat food like a “drug” that influences your hormone levels.
• Control your insulin levels to stay in the Zone.
• The Zone is a life-long dietary strategy.

You Can Have It Both Ways
Dr. Sears writes that food should be enjoyed:

I’m always drumming in your head that food is a drug, but I also want food t be the ultimate pleasure.  You should be salivating over your Zone meals and treating yourself to a nice dinner at your favorite restaurant.  The sheer enjoyment of food is an integral part of the zone plan, and I don’t want to deny you any of the eating pleasures you’ve experienced in the past.  All you need to do is follow some simple guidelines, and you can eat the way you’d like and stay in the Zone.  You can have it both ways.

Six Guidelines for Eating Out
Dr. Sears provides six guidelines for staying in the Zone while eating out:

• 1. Eat ahead of time.  Have a Zone snack less than two hours before you go to the restaurant.  It’s much easier to dine in the zone and make the right food choices if your blood sugar is stable.
• 2. Skip the bread.  When you are seated, simply ask your server not to bring any bread or rolls to the table.  If you need something before your main course, have a glass of wine and a protein appetizer (like smoked salmon or shrimp cocktail).  Sipping your win, determine the protein entree you plan to eat (such as grilled chicken or fish.)
• 3. Substitute for low-quality side dishes.  Ask your waiter if you can replace any side dishes that are low-quality carbohydrates (pasta, rice, grains or other starches) with high-quality carbohydrates like steamed vegetables.
• 4. Create a Zone-size meal.  When the meal arrives, but a serving out of your protein entree that’s as big as the size and thickness of your palm.  Ask your waiter to wrap the rest of your entree up so you can take it home.  Of course you still eat all of your high-quality carbohydrates that came with the entree.
• 5. Divvy up dessert.  If you want a rich desert, eat only half and give the other half to your dining partner.  Of course, if you opt for fresh fruit, you can eat the whole thing.
• 6. Give yourself a little leeway.  Finally, if you consume too many carbohydrates or too many calories at a meal, don’t worry that you’ve done irreperable damage.  You can reset your hormonal system if you make sure your next meal is a Zone meal.

Chinese
Dr. Sears provides tips for when you dine Chinese:

Forget the rice, and you have all the makings of a great Zone meal.  Grilled fish or chicken, stir-fried chicken, or tofu dishes are great sources of protein.  Choose a protein dish that’s piled high with abundant levels of high-quality carbohydrates, such as vegetables, to accompany your high-protein choice.

Italian
Dr. Sears provides tips for when you dine Italian:

This is always a potential Zone disaster because of the heaping amounts of pasta and bread piled on your plate.  Try the chicken or fish entrees served with extra vegetables instead of pasta.  Drizzle on some olive oil to enhance the flavor of your salads and cooked vegetables.  If you want pasta, have it as a small side dish.  I wouldn’t recommend pasta though, if you’re planning on drinking wine, since you’ll eat far too many carbohydrates for a Zone meal.

Japanese
Dr. Sears provides tips for when you dine Japanese:

Japanese cuisine is more Zone balanced thatn what you typically find in a Chinese restaurant, but you still should avoid the rice.  Fish and tofu entrees with abundant amounts of steamed vegetables are great.  Even sushi is not a bad balance of protein and carbohydrate.  (Helpful hint — A breaded protein dish like tempura is not a high-quality Zone protein choice.)

Mexican
Dr. Sears provides tips for when you dine Mexican:

This is another potential Zone disaster area because of the large amounts of low-quality carbohydrates, especially chips, refried beans, rice, and tortillas.  You can stay in the zone though, if you choose the chicken fajitas.  Always ask for corn instead of flour tortillas to decrease your carbohydrate intake, and for extra vegetables in place of the rice and beans.  Don’t forget to dab on a little guacamole, which is a great source of monounsaturated fat.

French
Dr. Sears provides tips for when you dine French:

If you’re eating in a gourmet French restaurant, you’ll probably be in Zone heaven.  You’ll be served a small serving of protein piled with plenty of crisp colorful vegetables lightly dressed in olive oil.  enjoy the wine and the meal.

Pizza Parlors
Dr. Sears provides tips for when you eat at pizzerias:

Yes, you can still eat pizza in the Zone.  It’s not the highest-quality meal you can find, but it’s OK on occasion.  Order the thin crust pizza instead of the thick crust and make sure that you have a protein-rich topping like cheese, chicken or even anchovies.  Then eat the topping of every slice, but only eat every other crust.  To make your pizza more satisfying, order extra vegetables as a topping.

Dining Out for Business Travelers
Dr. Sears provides an example of breakfast, lunch, dinner and snacks when you’re on the road:

• Breakfast – Egg-white omelet with a side order of oatmeal.  This is the ultimate power breakfast.  Just don’t eat the toast and the hash brown potatoes.
• Lunch – Chicken Ceasar salad with fresh fruit for desert.
• Dinner – Grilled fish with extra vegetables in place of the starch.  Have fresh fruit for dessert.  Consider having a glass of wine with the dinner, and always pass on the rolls. 
• Road Snacks – Have 1 ounce of sliced turkey or of low-fat cheese with half a piece of fruit.

Things to Avoid When Eating Out
Dr. Sears suggests avoiding the following:

• Fatty meats (steaks, pork, lamb)
• Fried foods (including appetizers)
• French fries
• Chips
• Excessive amounts of starches (rice, pasta, and bread)
• Rich desserts (unless it is a very small portion size)

Key Take Aways
Here’s my key take aways:

• Get in the Zone before you go.  Have a Zone meal before you eat out.  This will help you make better food choices.
• Trade high-quality carbs for low.  Substitute your sides.  Choose starchy carbohydrates for fibrous carbohydrates.
• Cut your portions.  Eat your palm sized portion of protein, then take the rest home.
• For Chinese, choose a protein dish with vegetables.  Avoid breaded dishes when possible.
• For Italian, choose fish or chicken and a salad.  Avoid the pasta and breads. 
• For Japanese, avoid rice.  Sushi is not a bad choice.
• For Mexican, choose chicken Chicken fajitas.  Avoid the breads and starchy carbs.  Choose corn tortillas over flour tortillas.
• For French, enjoy the meal!
  
• For pizzerias, order thin crust, and top with chicken and vegetables.  Eat the topping of ever slice, but only eat the crust of every other slice.
• On the road, stay in the Zone.  For breakfast have an omelet, for lunch a chicken salad, for dinner fish with vegetables, and snack on cheese and fruit.

Five Steps to Supermarket Shopping
Dr. Sears provides the following tips for food shopping while staying in the Zone:

• Step #1. Always go with a list.
• Step #2. Stay mainly on the periphery.
• Step #3. Make the produce section your foray into new adventures.
• Step #4. Go for fresh meat and poultry rather than the deli counter.
• Step #5. Consider buying organic produce.

Step #1. Always go with a list.
Dr. Sears writes:

Go prepared with a list of high-quality Zone foods, and stick with that list.  To help you stick with the list, make sure you don’t shop when you’re hungry.  Eat a Zone meal or snack before you hit the supermarket.

Step #2. Stay mainly on the periphery.
Dr. Sears writes:

Ever notice that the fruits, vegetables, meat, fish, and dairy products are all found in the outer aisles?  This is where you want to spend most of your time.  Avoid the center aisles, which contain the processed foods like cereals, pasta and snack foods.  And of course, avoid the bakery at all costs.

Step #3. Make the produce section your foray into new adventures.
Dr. Sears writes:

OK, you may find it hard to pass up the new brand of chocolates that screams to you from its bright pink bag.  But don’t the bright red tomatoes also beckon?  or the deep purple blackberries?  Go to a supermarket that displays appealing produce, free of bruises mold, and brown spots.  You’ll be more tempted to dive into the colorful delights.

Step #4. Go for fresh meat and poultry rather than the deli counter.
Dr. Sears writes:

With the exception of cooked turkey breast, you probably can’t find much higher-quality protein at the deli.  Head instead for the fish counter and the fresh meat choices.  Just make sure that any beef or pork you buy is well trimmed, preferably a “select” grade that is low in saturated fat.  You will probably still have to do some extra trimming of any separable fat to make it a good Zone protein choice.  Realize that the deli turkey breast and chicken breast are of lower protein quality than fresh poultry.

Step #5. Consider buying organic produce.
Dr. Sears writes:

Organically grown fruits and vegetables are higher-quality Zone foods than nonorganically grown produce.  This is because they are pesticide and herbicide free, and some research suggests that these chemicals can have negative effects on your hormonal systems.  I realize that organically grown produce is more expensive, but I think the added cost is well worth the health benefit.  Also, consider buying your produce from a farm stand or one of the farmer’s markets growing increasingly common in major cities.  Although this produce isn’t necessarily organically grown, it’s fresher than the produce you find in the supermarket and thus probably has a higher nutrient content.

Frozen vs. Fresh
Dr. Sears makes the case for frozen foods:

If you are like most people, you probably shop with the best intentions to buy fresh vegetables and fruits.  Unfortunately, you’ve probably also come to realize that the shelf life of such fresh produce doesn’t always conform to your daily schedule, and you may be sick of throwing away spoiled vegetables that you never got a chance to cook or fruit that has turned to mush.  If this is the case, you have two options: (1) Consider purchasing fresh produce two or three times each week. (2) Use frozen fruits and vegetables.

The quality of frozen produce has dramatically increased over the years, and the shelf life will always be greater (usually about two months before freezer burn begins to set in).  Furthermore frozen fruits and vegetables usually contain higher amounts of vitamins than fresh produce.  This is because they are quick-frozen within hours after harvest to reach your local food distributor.  From there you can expect a few more days before it gets to the supermarket and is bought and eaten by you.  During this time the vitamin content of the food is constantly decreasing.  By using frozen fruits and vegetables, you get maximum nutrition and convenience for the least cost.

Getting Out of Meal Ruts
Dr. Sears suggests varying your foods:

Most people find it’s easy to get stuck in a meal rut, preparing the same meals over and over again, week after week.  It’s easy, mindless, and less trouble than pouring through new recipes.  Still, I urge you to try a new food or two every week — or even every day if you cans swing it.  Just as you can make minor adjustments to your favorite meals to make them Zone-friendly, you can also make a few changes to your Zone meals to get the highest-quality foods.  Within a few weeks, you’ll have a formidable pharmacy of “drugs” to pick and choose from that will dramatically improve the quality of your life.

Key Take Aways
Here’s my key take aways:

• Make a list.
• Spend more time on the periphery than the aisles.
• Make exploring fresh produce an adventure.
• Choose fresh meat and fish over the deli department.
• Consider organic.
• Consider frozen foods.

High-Quality Carbohydrates (Think Anti-Oxidants)
Dr. Sears writes that the key to high-quality carbohydrates is to think anti-oxidants:

My definition of high-quality carbohydrates is one that does two things: (1) provides anti-oxidants and (2) keeps your blood sugar and insulin levels as stable as possible.  Anti-oxidants are essential because they quench free radicals, those unstable molecules in your body that wreak havoc on healthy cells and tissues.  Excess free-radical production remains the biggest impediments to your quality of life.  Although you need some free radicals to transform food into energy, any excess production of them (caused by eating too much food in general) triggers a breakdown in all areas of your body.  Free radicals degrade your cellular DNA, which can turn a healthy cell into a cancerous one.  They can also cause inflammation leading to heart disease, arthritis, and even wrinkles.

Three Factors to High-Quality Carbs
Dr. Sears considered three factors to determine the top-quality carbohydrates for his Top 100 Zone Foods list:

• Factor #1: anti-oxidative capacity.
• Factor #2: Glycemic index.
• Factor #3: Soluble fiber content.

Factor #1: Anti-Oxidant Capacity
Dr. Sears looks for carbohydrates with high anti-oxidant capacity:

When calculating the highest-quality carbohydrates for my Top 100 list, I looked first at fruit’s or vegetable’s total anti-oxidative capacity per gram of carbohydrate.  This includes not only the essential anti-oxidants such as vitamin A (often in the form of beta-carotene) and vitamin C, but also the braod array of nonessential anti-oxidants (like lycopene and other phytochemicals) that are packed into each gram of carbohydrate.  Anti-oxidant capacity is based on the strength that a certain food has to neutralize a given number of free radicals.  I ranked fruits and vegetables based on their anti-oxidant capacity per gram of carbohydrate.

Factor #2: Glycemic Index
Dr. Sears looks for carbohydrates with a lower glycemic index and lower glycemic load:

This is a measure of how rapidly your body breaks down carbohydrates in a particular food into the simple sugar glucose and how quickly this glucose gets into your bloodstream.  The faster a carbohydrate gets into your bloodstream, the faster the rise in your blood sugar and the faster the insulin is secreted to drive this excess glucose into storage in the muscle and liver.  The concept of the glycemic index only became well known during the past decade as nutritionists began to realize that many politically correct complex carbohydrates, like potatoes, actually caused faster rises in blood sugar than, well, table sugar.  The more rapidly the blood sugar increases, the more insulin is released.

Factor #3: Soluble Fiber
Dr. Sears looks for high soluble fiber in his carbohydrates:

This is the last factor I use to determine whether or not a carbohydrate is top Zone food.  Soluble fiber slows down the rate of entry of carbohydrates into the bloodstream, and this reduces insulin stimulation.  This factor can move some of the relative losers on the anti-oxidative index into winners.  This is the saving grace for apples, oatmeal, barley, and beans, which are relatively low in anti-oxidative capacity,but high in soluble fiber.  To qualify for the Top 100 Zone Foods list, a carbohydrate should have at least 0.3 grams of soluble fiber per Zone Block of carbohydrate.

According to Dr. Sears, the following have virtually no anti-oxidative capacity:

• Bagels
• Pasta
• Rice

High-Quality Protein (Think Low Fat)
According to Dr. Sears, the key to high-quality protein is to think low fat:

I define the quality of a protein source by its fat content.  Realize that all protein (even tofu) contains fat.  To quality for my Top 100 Zone Foods list, a protein choice must contain at least twice as much protein as fat.  This eliminates most cuts of beef, pork, and lamb, with a few exceptions like well-trimmed beef tenderloin.  Switching from high-fat protein choices to lower-fat ones will reduce your intake of saturated fat.  This will not only decrease cholesterol levels but also make the insulin receptors in your cells more responsive to insulin so that your body needs to make less of this hormone.  At the same time, you’ll also splash your intake of health-damaging Omega-6 fatty acids, a type of polyunsaturated fat found in all sources of protein.  This type of fat serves as the building block for certain types of eicosanoids that can accelerate the development of heart disease, cancer, Type 2 diabetes, and arthritis.

Excellent Protein
According to Dr. Sears, the following are excellent Zone protein sources.  The number in parentheses is the Zone protein quality.  The higher the number the better.

• (44) Mackeral
• (40) Turkey breast
• (30) Haddock
• (30) Cod
• (30) Salmon
• (25) Soybean hamburger crumbles
• (22) Tuna steak
• (22) Turkey breast, deli
• (21) Lobster
• (20) Sea bass
• (20) Snapper

Very Good Protein
According to Dr. Sears, the following are very good Zone protein sources.  The number in parentheses is the Zone protein quality.  The higher the number the better. 

• (18) Chicken breast
• (16) Freshwater bass
• (15) Trout
• (12) Cottage cheese (1%)
• (9) Chicken breast, deli
• (9) Tuna, canned in water
• (7) Soy imitation meat products
• (6) Emu

Good Protein
According to Dr. Sears, the following are good Zone protein sources.  The number in parentheses is the Zone protein quality.  The higher the number the better. 

• (4) Pork tenderloin, well-trimmed
• (4) Tofu, extra-firm
• (3) Beef tenderloin, well-trimmed
• (3) Tofu, firm
• (2) Tempeh
• (2) Tofu, soft

Low-Quality Protein
According to Dr. Sears, these are low-quality protein foods.  They are fatty beef and pork products that contain relatively high amounts of fat and therefore high amounts of saturated and Omega-6 fats.

• (0.6) Ground beef (27% fat)
• (0.3) Sausage
• (0.2) Bacon

High-quality Fat: Think Monounsaturated Fat
According to Dr. Sears, the key to high-quality fat is to think monounsaturated fat:

Although I expend many more words discussing carbohydrates and protein, fat is not just a footnote.  It’s just as critical a part of the Zone.  This is because high-quality fat will definitely fuel you better than low-quality fat.  I define as high quality food that’s high in monounsaturated fats and low in saturated and Omega-6 fats.  Saturated fat (found in whole milk dairy products and fatty red meat) can raise cholesterol levels, which leads to heart disease.  Omega-6 fats, as mentioned above, can have adverse effects on the overproduction of “bad” eicosanoids associated with chronic disease.  Monounsaturated fats, on the other hand, have no effect on insulin, cholesterol, or eicosanoids.  Some research suggests that they may even raise “good” (high-density lipoprotein, or HDL)) cholesterol levels.  As a result, populations that consume high levels of monounsaturated fat have very low levels of cardiovascular disease and improved longevity.

Excellent Quality Fats
According to Dr. Sears, the following are excellent quality fats.  The number in parentheses is the Zone fat quality.  The higher the number the better.

• (4.5) Macadamia nuts
• (3.6) Olive oil
• (3.5) Olives

Very Good Quality Fats
According to Dr. Sears, the following are very good quality fats.  The number in parentheses is the Zone fat quality.  The higher the number the better.

• (2.3) Avocado
• (2.2) Canola oil
• (2.2) Almond butter
• (2.0) Almonds

Good Quality Fats
According to Dr. Sears, the following are good quality fats.  The number in parentheses is the Zone fat quality.  The higher the number the better.

• (1.6) Cashews
• (1.1) Peanuts

Poor-Quality Fats
According to Dr. Sears, the following are poor-quality fats:

• (0.9) Lard
• (0.4) Butter
• (0.2) Safflower oil
• (0.2) Soybean oil

You Can Choose How You Feel
According to Dr. Sears, you can choose to hold the reigns and control your hormones by choosing Zone meals:

Consume one Zone meal after another, and you will achieve consistent hormonal control for your lifetime.  Use low-quality foods on the other hand, and you will simply lose the reigns and allow your hormones to run wild.  The choice should be easy to make.

Key Take Aways
While I’m not surprised by the data, I do like the precision and clarity that the food ranking creates.  Here’s my key take aways:

• For high-quality carbs, think anti-oxidants.  High-quality carbohydrate sources have high anti-oxidative capacity, low glycemic impact, or high soluble fiber content.
• For high-quality protein, think low fat.   This is probably the first time I’ve actually seen a crisp breakdown of why to choose low-fat over high-fat protein.  Choosing proteins that have twice as much protein as fat has the compound effect of lowering your intake of saturated fat, cutting your intake of Omega-6  fatty acids, decrease your cholesterol levels, and  make the insulin receptors in your cells more responsive to insulin so that your body needs to make less of this hormone.  Impressive.
• For high-quality fat, think monounsaturated.   Saturated fat can raise cholesterol levels.  Monounsaturated fats have no effect on insulin, cholesterol, or eicosanoids, and potentially raise “good” cholesterol levels.   
• Choose your foods based on quality.  I really like knowing the caliber and impact of my food choices.  I only had a vague idea of food quality based on simple rules like choosing fibrous carbs over starchy carbs, and choose deeper, darker colored vegetables over lighter ones.

Zone Food Blocks
According to Dr. Sears, each Zone meal consists of Protein Blocks, Carbohydrate Blocks, and Fat Blocks:

• Protein Block.  One Protein Block contains 7 grams of protein.  The average male needs four Protein Blocks and the average woman needs three Protein blocks.  
• Carbohydrate Block.  One Carbohydrate Block contains 9 grams of carbohydrates.  3 Carbohydrate Blocks would contain 27 carbohydrates.  4 Carbohydrate Blocks would contain 36 carbohydrates.
• Fat Block.  One Fat Block contains 3 grams of fat.  3 Fat Blocks would contain 9 grams of fat.  4 Fat Blocks would contain 12 grams of fat.

The keys to the Zone Blocks:

• The number of Protein Blocks you need depends on whether you are a man or a woman.
• Eat the same number of Carbohydrate Blocks at every meal as Protein Blocks.
• Eat the same number of Fat Blocks at every meal as Protein Blocks.

The Average Woman Zone Food Blocks
According to Dr. Sears, a typical woman needs the following blocks for a Zone meal:

• 3 Protein Blocks.  The average woman will need three Protein Blocks for each meal (21 grams of protein.)  That translates into about 3 ounces of high-quality protein.
• 3 Carbohydrate Blocks.  The average woman will need three Carbohydrate blocks for each meal (27 grams of carbohydrates.)
• 3 Fat Blocks.  The average woman will need three Fat Blocks (9 grams of fat.)

A typical Zone meal for a woman would contain about 9 grams of fat, 21 grams of protein, and 27 grams of carbohydrates.

The Average Male Zone Food Blocks
According to Dr. Sears, a typical man needs the following blocks for a Zone meal:

• 4 Protein Blocks.  The average man will need four Protein Blocks for each meal (28 grams of protein.)  That translates into about 4 ounces of high-quality protein.
• 4 Carbohydrate Blocks.  The average man will need four Carbohydrate Blocks for each meal (36 grams of carbohydrates.)
• 4 Fat Blocks.  The average man will need four Fat Blocks for each meal (12 grams of fat.)

The typical Zone meal for a man would contain about 12 grams of fat, 28 grams of protein, and 36 grams of carbohydrates.
