Your Lifesize Order


What do I get in the Lifesize kit?

 The Lifesize Basic Kit gives you all the tools you need to get your portions right every time.  It comes with:


8 Lifesize measuring devices and a sturdy countertop/wall mountable storage unit

Our patented measuring devices help you portion out all the foods you eat easily and quickly.  No weighing or guessing.  And no memorizing anything because…

The Lifesize Wall Chart

Lists the Lifesize portions for all the foods you eat.  And to keep Lifesizing fast and easy, your measuring devices are color-coded to match a box on the wall chart. The chart is intuitive, colorful and easy to read. You’ll be able to start Lifesizing at your very next meal.

The Lifesize Quickstart

The Quickstart shows you the basics of using the Lifesize tools, and gives you a quick outline of the complete 5 Step Lifesize Program. Our Quickstart gets you up and running as soon as you open the box.

Two Lifesize DVD’s

DVD 1 is “Ready Set Go!”  Watch this first.

Narrated by Myles and Elisabeth Berkowitz and Steven Kates, the DVD’s show you how to use Lifesize tools, show you the portion sizes for most of the foods you eat, and guides you step by step through the entire Lifesize program.  Also includes a quick start for those who want to get up and Lifesizing in 15 minutes. Filled with animation and graphics.

DVD 2 is “Keep Going”

Myles walks you through the Lifesize Wall Chart and all the Lifesize food categories.  He shows you the portion sizes of all the foods on the wall chart and teaches you how to portion special portions like sandwiches and pizza.  He also teaches you how to portion all the foods that aren’t on the chart too. This is a great reference tool to watch when you have a question about a portion.

The Lifesize CD which has The Lifesize User’s Manual and Reference Guide

For those who prefer to learn by reading, we include a CD that has all the material on the DVD’s in a manual and a reference guide in PDF files.


Can I use Lifesize if I’m a diabetic?

The best answer I or anyone can give you is that you must consult your physician about Lifesize or any eating program or diet you want to go on.


Show your doctor our website.  If he wants to contact me or Steven and ask some questions please let us know and we will contact him or her.

I am not a physician, but Steven and I consulted many physicians and physiologists and nutritionists as we created the Lifesize tools and program.  Every physician we spoke to was very supportive of Lifesize.

Many many doctors believe that eating in moderation and portion control is the best way for people to lose weight and keep it off.  And the most important thing you can do for your health is to get to your proper, healthy weight.

Specifically to the point about diabetes – many doctors use Lifesize with their diabetic patients. They find it very helpful to use our portioning devices to show their patients what portion sizes of foods they should be eating.

And even if they don’t allow their patients to follow our 5 step program exactly, the tools we provide are so easy to use and helpful that doctors easily modify our program for their diabetic patients.

For example, doctors use our Carbs device to help their diabetic patients separate out carbs in their diet, and to portion out their Carbs.  Some change our directions to specifically require their patients to possibly eat 1 Carbs device of carbs a day.

We don’t tell people what to eat.  We insist that they eat whatever they want, but in the Lifesize portions.  This obviously wouldn’t work for a diabetic and we warn people about this in our written material and in our video.

Your doctor knows you best and might have other ideas for you.  So show your doctor our product, or have him call us to talk to us, he or she should decide whether or not he could use these tools in controlling your diabetes.

Hope this helps!



Are the Lifesize measuring devices dishwasher safe?

Yes. You can put them in your dishwasher.  They are dishwasher and food safe.

I’ve had my Lifesize measuring devices for over 4 years and they have held up perfectly.



The Lifesize measuring devices are not microwave safe.



Are the Lifesize measuring devices microwave safe?


The Lifesize measuring devices are not microwave safe.

However, you do not want to cook your food in our measuring devices anyway.  You want to cook your food the way you love it, and the way you always have cooked them.  Then you use the measuring devices to portion out your food from your pots and pans and dishes on to your plate.



Hey – I didn’t get the Lifesize Manual and Lifesize Reference Guide!

You probably did and you don’t realize it.  The manual and reference guide are books.  But don’t look for books in your kit!

The manual and reference guide are both on the CD that came in your kit.  The CD has all the printed material we sent you.

We tried to be “green” and of course hold down the costs for shipping and printing.

Just put the CD in your computer and see if the written material is there.

But also, remember, the written material on the CD covers pretty much the exact same material that’s on the DVD.  I thought it would be better to learn how to Lifesize by watching; and a little more entertaining too.

Plus, I wanted you to see the portion sizes of food too.

So try to watch the DVD’s.

We included the CD’s for people who prefer to learn from written material, or want to have all the information written out as a back-up or easy reference.

And of course, if you in fact did not get the CD, just contact me and I’ll send one to you.



My DVD doesn’t work

We will send you replacements right away.  However…

Before I send you the replacements, can you just double check that you weren’t putting the CD in your DVD player…Like I always do!

Remember, you get 2 DVD’s and 1 CD in the kit.

And of course, if it is our mistake, we’ll send you a working DVD ASAP.



What is your return policy?

If you get our kit and want to return it, we will refund you the cost of the kit.

My fulfillment house (our warehouse and shipper) is moving. So for now, just send it back to me, and I’ll refund your credit card for the kit.

The Lifesize Program

What Science and Research Backs Up The Lifesize system and your claims?

We’ve done extensive research, including having an independent study commissioned by Colorado State University, which you can read HERE or download the PDF HERE

We’ve also created this special Lifesize Science section that explains all the claims we make, and what research backs up those claims.  It’s important to us that you don’t just Lifesize, but that you understand why and how it works!

What if the amount of food I’m allowed on Lifesize is too much for me to eat?

The Lifesize portions are the most you should eat. If you find that you don’t need quite that much food…great. Don’t eat it.

Eat until you’re truly full, and satisfied. But not more than that.

The purpose of eating is to satisfy a biological need…and hopefully for enjoyment. It goes against our biology and isn’t enjoyable to overeat…but we don’t realize that until about 15 minutes after we overate!

So, if you don’t need as much food as a Lifesize portion, don’t eat it. But there will be days that you are going to be hungrier, or meals that you want to eat more food, so you will benefit from knowing the largest amount of food you should eat.

Can I drink alcohol on the Lifesize program?

The point of Lifesize is that you must eat and drink everything you love…or you will inevitably fail the diet in the long run.

We teach you the right portions to eat of all the food you love, how to add water and fruits and vegetables and low fat dairy around that so you stay full and satisfied.

We also came up with portion sizes that not only factor the calories, but also the way we eat and drink the foods.

For wine, the Lifesize portion is 2 glasses because we usually have wine with dinner and that will be enough to have with dinner. Not too little…and not too much. And the glasses are reasonable, bartender pours.

Beer – 2 glasses or bottles.
Martini – That’s a cocktail we usually drink before dinner. So 1 is what we should shoot for and is the Lifesize portion.


P.S. I drink wine with dinner often, so I can verify that this works and is enough for a dinner!

Does Lifesize work for vegetarians?

Lifesize does work for vegetarians. We portion everyone’s carbs, dairy, saucy dishes, snacks, etc.

There are things we teach you about drinking water and seconds and snacking and exercise that will also help you lose weight.

The only thing different for you is that you won’t be portioning out meats. Ironically, we have you portion out Tofu and vegetarian substitute dinners (which are higher in calories than people realize) with our Meats device.

And for the record, I apologize to vegetarians about that in our manual!



Losing Weight on Lifesize

Question: Are the Lifesize portions the same for men and women, and for people of different sizes?

The Lifesize portions are the same for men and women and for a majority of people of different sizes. These are the portion sizes that thin people eat.

There was an 80 pound difference between me and my wife when we started Lifesizing. And we both ate Lifesize portions to lose all our weight.

This works.

But remember, we are talking about portion sizes not caloric intake.

On the Lifesize Program, the fact that men and women and different size people have different caloric intake is covered by the free choice people have in the foods they eat and by adding different amounts of FREE FOODS to their daily diet and on their plate at each meal.

In other words, my wife and I are different sizes.  However, the portion sizes that I eat at dinner with my wife are the same that she eats. Lifesize portions.

But…don’t confuse calories with portion sizes.

I will actually eat more calories at dinner and during the day than my wife.

Remember, on the Lifesize Program, we are allowed to eat Free Foods. All fruits, all vegetable and most low fat dairy are totally free. You do not have to portion these foods out. And by cutting down on the portion sizes of more caloric foods and adding these FREE FOODS, people on Lifesize can make sure that they are never hungry.

So at dinner, I might have the same portion of meat or pasta as my wife, the same amount of wine (we’re in California!) but I might have more vegetables or some fruit after dinner that she doesn’t have. And while those may be FREE FOODS, they still have calories…and they are still filling.

Likewise, I will eat more calories during the day by my choice in foods. For example, even though we might eat the same food at dinner, for breakfast my wife might have a bowl of cereal and I will have a peanut butter and banana sandwich. I ate more calories than she did, but this is allowed and it sustains me during the day.

Also, I will probably eat more FREE FOODS during the day than my wife does, which again means more calories. I might grab a banana in the morning and a low fat yogurt during the afternoon. Those are FREE FOODS, but they also have calories.

Of course, there are couples who want to Lifesize together but who are bordering on extreme differences on the bell curve.  For example, the above discussion might not hold for a woman who is 4’8” and her basketball husband who is 6’8″.  This couple might experience slightly more difference in weight loss speed and in the amount of food they eat.

But Lifesize portions will work for most couple and the great majority of Americans of both sexes and in all shapes and sizes and body frames.

Also note – men do tend to lose weight faster than women, on any diet.  And if you one person in the couple has to lose 80 pounds and the other has to lose 20, the person who has to lose 80 pounds will probably lose weight faster.

But again, most people will lose weight on these portions and on the 5 step Lifesize Program. And you will keep it off too..because Lifesize is a great maintenance program for life.


The Lifesize portions are the most you can eat. If you find that you don’t need quite that much food…great. Don’t eat it. Eat until you’re truly full, and satisfied. But not more than that. The purpose of eating is to satisfy a biological need…and hopefully for enjoyment. It goes against our biology and isn’t enjoyable to overeat…but we don’t realize that until about 15 minutes after we overate!

So, if you don’t need as much food as a Lifesize portion, don’t eat it. But there will be days that you are going to be hungrier, or meals that you want to eat more food, so at Lifesize we teach you the largest amount of food you should eat.

What if I want to lose weight faster on Lifesize?

On the Lifesize Program, you are allowed to eat 6 Lifesize Portions over 3 meals…plus a snack and/or dessert.

Dr. Chris Melby did a study on Lifesize at Colorado State University. He’s head of the fitness and nutrition department over there.  He concluded that Lifesize creates steady weight loss, real weight loss, and the Lifesize Program teaches portion sizes and eating habits that will allow you to keep that weight off for life. That’s why we know this works.

But here’s what we realized from the study. And it’s such a simple, brilliant idea I would love to say that I came up with it…but I didn’t! Melby did.

If you want to lose weight faster, especially when you first go on Lifesize, then cut back from 6 Lifesize portions to 5. By also eating FREE FOODS, this might be all the food that you will need.

But, and this is a huge “but,” if you feel hungrier during any particular day, just go back up to 6 Lifesize portions.

Also, as everybody does, you might gain a few pounds over the course of a couple of months. Not too bad, but to lose that weight…cut back down to 5 Lifesize portions. Then go back to 6 when you hit the right weight – as a maintenance mode.



Specific foods and Portions


How to portion a Lifesize sandwich

There are a few dishes that we eat all the time – like sandwiches and pizza – that you will need a little more guidance to get the right amount of food. You are building these dishes, so they aren’t in a box on the Wall Chart.

There are two things to consider when you make a Lifesize sandwich –

How to make the right size sandwich

How to count that sandwich in your 6 Daily Lifesize Portions

This FAQ will address making the right size sandwich, or the right portion size of a sandwich.

When you make a sandwich, you know the Lifesize portions of turkey and ham and Swiss cheese and American cheese you should use; and the right portion of mayo to spread in your sandwich also. But what’s to stop you from building a sandwich that has all the right portion sizes of foods, but way too many portions of foods in it…and way too many calories?

So here are a few additional simple tips to make your life easy and your sandwich portions perfect.

A Lifesize sandwich:

A Lifesize sandwich is two Lifesize portions of food in between your bread.

Let’s break that down even further.

You start with the Lifesize portion of bread. Check the Carbs Natural Portions box on the Lifesize Wall Chart. You’ll see that the Lifesize portion of bread is either:

2 slices
1 roll
6″ baguette
1 hamburger bun
2 hotdog rolls

It can be any kind of bread – white, wheat, rye, etc. Just eat the kind of bread that you like.

And you can put two Lifesize portions of any food you want in between the bread. You can choose a combination of two out of…

1 Lifesize portion of meat
1 Lifesize portion of cheese
1 Lifesize portion of a spread

Don’t think about what you put in between your bread, focus on how much you put in between your bread. You can use whatever combination of two foods you want to fill your sandwich as long as you use the Lifesize portion of these two foods.

Common sandwich fillings that are 2 things would be:

Turkey and Swiss cheese
Cheeseburger (burger and cheese)
Peanut butter and Jelly
Grilled Chicken with some mayo
Leftovers from dinner and Russian dressing

Every food in the filling should be the Lifesize portion of that food. So for a ham and cheese sandwich you would use…

A LifeSize portion of ham and
A LifeSize portion of cheese

Remember, the Lifesize portions for ham are –

1 LifeSize Meats Device of ham or
4 deli slices of ham

For cheese –

Either 1 Dairy Device of cheese or
2 regular deli slices of cheese or
1 large deli slice of cheese (usually how Swiss is cut)

For a peanut butter and jelly sandwich you would use…

2 Toppings Devices of peanut butter and
2 Toppings Devices of jelly
Of course FREE FOODS are FREE. So you don’t have to count FREE FOODS as one of the two foods you can use for a sandwich filling.

So you can add lettuce and tomato to a turkey and Swiss sandwich because all vegetables are FREE. If you add a FREE spread like mustard to your sandwich, you don’t have to portion it or count it either.

And now your turkey and Swiss sandwich would actually have five different foods as part of the filling –

A LifeSize portion of turkey and
A LifeSize portion of cheese and
Lettuce (FREE)
Tomato (FREE)
Mustard (FREE)

But if you add a spread like regular mayonnaise to your sandwich, that’s not FREE. And now you would have three portions of food inside your bread.

A LifeSize portion of turkey and
A LifeSize portion of cheese and
A LifeSize portion of mayo and
Lettuce (FREE)
Tomato (FREE)

You can have your mayonnaise but you just have to end up with two Lifesize portions of food in between your bread. So if you have three portions of food, just change one of your portions to a FREE FOOD. So you could have…

A LifeSize portion of turkey and
A LifeSize portion of cheese and
Low-fat mayo (FREE)
Lettuce (FREE)
Tomato (FREE)


A LifeSize portion of turkey and
A LifeSize portion of mayo and
Low-fat cheese (FREE)
Lettuce (FREE)
Tomato (FREE)

It’s that simple.

FREE FOODS come in handy when you start to deal with spreads and other things you want to throw on your sandwich. Most of the time, the substitution choices you can make will be the low-fat versions of the cheeses or the spreads you put on your sandwiches.

Fast food sandwiches
Too much stuff

When you eat at a fast food restaurant, many times they put regular mayo or a “special sauce” on your sandwich. So if you have a cheeseburger, you now realize that it’s a little too much food – the filling in this sandwich is made up of three things not two.

Special Sauce

You probably won’t be able to order a low-fat alternative to the cheese or special sauce. But you can do a couple of things…

You can take one food out of the cheeseburger when you get it (take out the cheese or wipe off the sauce). Or you can order a burger with special sauce or a cheeseburger with no special sauce.

And don’t purposely order a sandwich that you know has too much food in it. A bacon cheeseburger has…

Special Sauce or Mayo

That’s four things! You don’t need all that food to enjoy a sandwich for lunch or dinner.

Too big

The other problem you will run into at fast food restaurants is that many times they serve sandwiches that are way too big.

An over-stuffed deli sandwich has a lot more meat in it than the LifeSize portion of meat. A double cheeseburger has two patties instead of the LifeSize portion size, which is one patty.

The best way to avoid eating a sandwich that is way too big is not to order a super-size sandwich. When you go to a fast food restaurant order the smallest sandwich on the menu. Order:

A regular burger, or
A regular cheeseburger

Don’t order:

A double burger or
¼ pounder or
anything with the word “big” or “super” in it!

When you are at a Subway, order the 6” smaller sandwich choice instead of the 12” larger sandwich choice.

But if you can’t avoid getting a super size sandwich – for example, you’re in a deli and they make their sandwiches a certain way – then just eat half of the sandwich and save the rest for later.

An over-stuffed deli sandwich has a lot more meat in it than the LifeSize portion of meat. Eat half of it for your lunch, and the rest later for a snack or dinner, or lunch tomorrow.

How do I count a sandwich on the Lifesize program? It seems like it should be 3 of our 6 daily portions, but you count it as only 1. Why?

There are two things to consider when you make a Lifesize sandwich –

How to make the right size sandwich

How to count that sandwich in your 6 Daily Lifesize Portions

This FAQ will address counting your sandwich in your 6 Daily Lifesize Portions.


Here’s the short answer:

1 Lifesize sandwich is 1 Lifesize portion

We know there’s more food in a Lifesize sandwich than in most Lifesize portions of other foods, but we don’t care. You’re not counting calories, you’re counting Lifesize portions.

And we don’t want you to torture yourself when you eat a sandwhich. You don’t want your sandwich to be 3 or a half of your daily Lifesize Portions.

Keep the sandwich as 1 Lifesize portion. No stress and no guilt. And believe us, when you eat a sandwich, it’s usually more filling, and you end up eating less in between meals or at your next meal.



Mexican Food - Lifesize portions

A lot of people eat Mexican food in restaurants.  Here’s what we believe are the proper portions of Mexican food in restaurants, starting with a general rule:

Anything that says “Grande” or “Big”…don’t order!  If that’s all there is on the menu, have half.

Now here’s a handy guide for you when you eat Mexican food in a restaurant or buy it to go:

Tacos –

2 tacos (small, hard shell)

1 taco (large or soft shell)

Tacos in hard shells are usually smaller at fast food restaurants like Taco Bell.  The portion is 2.

Large tacos, tacos in Mexican restaurants, or soft shell tacos are usually bigger.  The portion is 1.

Burritos –

1 Convenience store burrito, frozen burrito and supermarket burrito

½ Gourmet or Mexican restaurant burrito

Burritos from 7/11 or frozen burritos are very common.  The size is 1.  Burritos in restaurants are usually larger.  The portion size is ½.  And save the rest for a snack later in the day or lunch the following day.

Enchiladas –

1 Enchilada

Although it looks like there is a lot of sauce and cheese on top, the enchilada themselves are usually small so the total calorie count is less than a burrito.

Quesadillas -

½ Quesadilla

This is a very cheesy and rich food.  And very filling too, so half a quesadilla should be tasty and filling.

Food Lifesize portion
Tacos 2 tacos (small, hard shell)1 taco (large or soft shell)
Burritos 1 Convenience store burrito, frozen burrito and supermarket burrito½ Gourmet or Mexican restaurant burrito
Enchiladas 1 Enchilada
Quesadillas ½ Quesadilla

If you’re making the burrito or tacos at home, you use Lifesize portions and measuring devices of course.

Here’s how you would make Lifesize tacos -

1. Portion out the meat in 1 Meats Device.

2. If you are using cheese, either sprinkle just a little bit of cheese on it for flavoring, and don’t worry about portioning it.

But if cheese is a major ingredient of your taco, then use 1 Dairy Device.

3. The vegetables are FREE.

4.  The shell

If you are using hard shells to make your tacos at home you will probably use 2 to put all that food in.  Hard shell tacos are usually smaller than soft shell tacos.

Plus, if you are using a hard shell for the taco, 1 hard shell taco is probably going to be too small an amount for you to psychologically be satisfied at a meal.

And this is important.  You need to walk away from the table being satisfied.  In this case, it’s not that 1 taco isn’t enough food. It’s just that we look at tacos and think we need at least 2 for a satisfying lunch or dinner.  It’s psychological, but don’t fight it.

Of course, don’t have 2 tacos if 1 is going to satisfy you!  That’s your call.  But don’t eat 3 tacos either.  That’s too much food.
